Detection unit  200  may include motion sensor  216 , sensor suite  240  (including particle sensor  220 , chemical sensor  224 , temperature sensor (not shown for clarity), humidity sensor (not shown for clarity), or any combination thereof), alarm  232 , battery  228 , electronics stack  236 , tampering sensor (not shown for clarity), similar or the same as components hereinbefore described with reference to  FIG. 1 . 
     In embodiments, and still referring to  FIG. 2 , device housing  204 , similar or the same as detection unit housing  168 , may be configured to enclose at least a portion of motion sensor  216 , sensor suite  240  (including particle sensor  220 , chemical sensor  224 , temperature sensor (not shown for clarity), humidity sensor (not shown for clarity), or any combination thereof), alarm  232 , battery  228 , electronics stack  236 , tampering sensor, and has a shape with at least one set of opposite, opposing surfaces. The shape of housing  204  may include any three-dimensional shape having one or more faces. In embodiments, the shape of housing  204  may be hollow, allowing housing  204  to enclose at least a portion of motion sensor  216 , sensor suite  240  (including particle sensor  220 , chemical sensor  224 , temperature sensor, humidity sensor, or any combination thereof), alarm  232 , battery  228 , electronics stack  236 , and/or tampering sensor. For example, in the illustrated embodiment of  FIGS. 2A and 2B , housing  204  may have a shape of a rectangular prism or a hollow box. According to embodiments, each face of the shape of housing  204  forms a respective wall of housing  204 . A wall may include a piece of material having opposite, opposing surfaces (e.g. an inner surface and an outer surface) with a thickness between them. 
     According to embodiments, and further referring to  FIG. 2 , a wall of housing  204  may include venting  208  which may allow for air to travel within housing  204 . Venting  208  may be accomplished by any number or combination of methods including, but not limited to slotting, screens, perforations, cutouts, pass throughs, milled holes, or injection-molded openings, to name a few. By allowing air to travel within housing  204 , vaporized aerosol containing chemical particles may be provided to the sensors enclosed with housing  204  for sampling. Venting  208  may be disposed on any or all walls of housing  204  to allow for directed airflow. 
     In embodiments, and still referring to  FIG. 2 , housing may be configured to enclose or encase one or more fans. Each fan may be disposed within housing such that the fan is configured to draw air into venting  208  and/or push air out of venting  208 . In embodiments, fans enclosed within housing may be configured to create a positive or negative pressure within housing such that air is pulled into and/or forced out of venting  208 . According to embodiments, creating a negative or positive pressure within device housing may allow for air to travel within housing so that it may be sampled by the sensors enclosed within housing  204 . In embodiments, power may be provided to the fans from battery  132 . 
     According to embodiments, and continuing to refer to  FIG. 2 , housing  204  may comprise a flapper that allows air to pass through venting  208  such as during sampling but does not allow high pressure bursts of air to enter the system. In other words, flapper may be configured to allow a low flow sampling (such as, for example &lt;1 m/s airflow) while preventing higher flow rates or bursts (such as, for example, &gt;1 m/s airflow). A flapper may be disposed near venting  208  and configured so that a sudden burst of air may force the flapper closed over at least a portion of venting  208  in order to protect the components enclosed within housing  204  from damage. A flapper may be made of mylar, aluminum, various plastics, or another undisclosed combination of lightweight materials. A closure of a flapper may be communicated wirelessly or through a wired connection to a respective electronics stack and/or servers  112   a - c  for the purpose of notifying a user that sampling is taking place or the possibility that tampering was detected, for example. A flapper, in embodiments may have an electrical connection-type sensor that can determine if the flapper is closed by the presence of a completed circuit within the sensor, this is merely an example as any contact sensor or grouping of sensors may accomplish this task. 
     For example, and with continued reference to  FIG. 2 , air may enter housing  204  and travel over an enclosed particle sensor  216  and chemical sensor  220  laminarly so that particle sensor  216  and chemical sensor  220  may sample the air. Laminar flow may be defined as non-turbulent flow with smooth streamlines and little to no mixing of layers of flowing particles. According to embodiments, an arrangement of particle sensor  220 , chemical sensor  224 , and/or any other sensors that may be present alone or in combination fully and/or partially enclosed within housing  204  may be sequential such that airflow is sampled by sensors in the order in which the sensors are reached by the airflow. 
     According to embodiments, and further referring to  FIG. 2 , housing  204  may include mounting hardware  212  for mounting detection unit  144  in a plurality of orientations and/or in a plurality of locations. Mounting hardware  212  may include threaded holes, clearance holes, hooks, slots, or other hardware interfaces that may accept or interact with standard hardware for mounting in a plurality of arrangements and orientations. In the exemplary embodiment  FIG. 2A  mounting hardware  212  may be arranged for mounting on a wall of a room. This is only an example and one of ordinary skill in the art would understand mounting hardware  212  may take another form for mounting the device on a ceiling or in a vehicle. Configuration of housing of entry unit  116 , communication hub  172 , repeater, and/or other elements of system  100  may be affected similarly. 
     According to embodiments, and with further reference to  FIG. 2 , housing  204  and enclosed components may also be configured in line with an air filtration system, a vehicle air system, an HVAC system, an air conditioning system, or any system which passes air and/or gaseous fluid through it. In embodiments, detection unit  200  may be configured to be only a subcomponent or process in a larger system such that it may detect information about a detection event and convey that to a larger system. These systems, both system  200  and the larger HVAC-type system, may be disposed in or on residential or commercial buildings, vehicles like airplanes, cars, and/or trucks, or any combination thereof, to name a few. Housing  204  may also comprise a screen configured to provide general information about the system, warnings or alerts, and/or health-related information configurable by a user or as reflected by sensor data from system  100 . 
     With reference to  FIG. 2B  an isometric cutaway view of detection unit  144  from  FIG. 2A  is shown. The disposition of previously shown sensors  216 ,  220 ,  224 , may alternatively be found within or on the device as well. In  FIG. 2B  electronics stack  236  is shown along with battery  228  and alarm  232 . One of ordinary skill in the art would understand that the arrangement of components within housing  204  are example embodiments and in other embodiments may take different forms allowing for different shaped housings, airflow directions, mounting arrangements, and environment  108  locations. 
     Referring again to  FIG. 1 , aerosolized substance detection system  100  and/or any unit thereof, including without limitation entry unit  116 , detection unit  144 , communication hub  172 , repeater node  176 , or the like may include a display such as, for example, a light-emitting diode (LED) display, liquid crystal display (LCD), electronic ink display, cathode ray tube (CRT) display, organic LED display, or any combination thereof. According to embodiments, display may be configured to display one or more alerts, measures and/or levels detected by sensor suit, battery  132  level (especially low battery  132 ), a temperature of environment  108 , a humidity of environment  108 , general health information, or any combination thereof. 
     In operation, entry unit  116 , detection unit  144 , repeater node  176 , and the communication hub  172 , may be configured to enable communication between any of entry unit  116 , detection unit  144 , repeater node  176 , and the communication hub  172 . This configuration may form a network of sensors that may be distributed in a variety of configurations best suited to the detection application. Communication hub  172  may act as a gateway for transmitting data to and from the cloud to nodes. Data transmitted to the cloud may be delivered to electronic device applications used to provide alerts, view data, system status including battery power, system maintenance messages, user access, or thresholding. Repeater node  176 , where present, may receive and re-transmit data to other nodes. Alternatively, some node configuration files, such as firmware, may be transmitted directly to the devices from the cloud as required. 
     Still referring to  FIG. 1 , entry unit  116  may act as a primary trigger for system  100 . When a triggering event such as movement is detected, entry unit  116  may send a signal to detection unit  144   s  and/or units directly or via communication hub  172  and/or repeater node  176  to wake up sensors; detection unit  144  may then power on for some time and transmit data to another element, such as without limitation communication hub  172 , server, and/or the cloud. Signal may then be transmitted from the cloud to an electronic device for processing. Signal from sensors may be compared to thresholds set in any unit of system  100 , a server, and/or an application operating on a mobile device in communication with system  100 , and if the signal exceeds the threshold an alert may be generated as a result. Thresholding algorithm may be stored, in a non-limiting example, at nodes and/or units of system  100  on firmware; in this case data processing may be done locally. In the above-described version only alerts may be transmitted to the cloud then to servers  112   a - c , electronic device application, such as mobile device applications, or the like. Algorithms to determine alert states may also be more advanced to include smoothing, peak picking, and/or second derivative calculations or machine learning to train the sensors to an environment  108 . Any unit of system  100 , node of system  100 , server, and/or mobile device in communication therewith may also receive warnings when a battery  132  in system  100  requires charging or if systems  100  is tampered with or disabled for any reason. 
     With further reference to  FIG. 1 , baselines and/or thresholds may be calculated and/or dynamically set as at any unit of system  100  as follows. A timer such as a watchdog timer, as described above, may turn on entry unit  116 , detection unit  144 , and/or other elements of system  100  at a configurable time to collect baseline data from sensors of sensor suite  148  at a regular interval, such as each day; any such element or combination thereof may be powered on for a configurable period of time, which may as a non-limiting example fall between 10 minutes and 60 minutes. A mean from data of each sensor, excluding zeros, and a standard deviation from the data of each sensor may then be calculated. A threshold may be established by adding a calculated mean value from each sensor to a calculated standard deviation of that sensor. A confidence factor may be applied by multiplying a standard deviation by a factor as well. Alternatively, a calculated mean value may be multiplied by a configurable variable then added to a calculated standard deviation to reduce influence of environment  108  noise. A confidence factor may be applied by multiplying standard deviation by a factor as well. In a non-limiting example, confidence factor may be calculated according to the following equation:
 
Baseline Threshold=Particle Count Mean +(Variable×σ)
 
Alternative Baseline Threshold=(Variable×Particle Count Mean )+(Variable×σ)
 
A resulting value may be stored in the system until the next watchdog timer event. In this embodiment for 24 hours, and/or until the next configurable wakeup for baseline collection.

     With reference to  FIG. 5  a flow chart illustrating a method for vaporized aerosol detection  500  is presented. At step  505 , a trigger sensor, such as a motion sensor, particle sensor, chemical sensor, and/or real time clock similar or the same as motion sensor  120 , particle sensor  152 , or chemical sensor  156 , respectively, may be active, for instance and without limitation in entry unit  116 , detection unit  144 , or the like. According to an embodiment, at  510 , the trigger sensor may be configured to detect a triggering event. For example, a motion sensor  120  of entry unit  116  may be configured to determine whether motion has been detected by detecting motion, proximity, and/or presence of one or more objects  124   a - b  within a first area or location of an environment  108 . In embodiments, detecting whether a triggering event has been detected in an environment  108  may include comparing captured measurements (such as motion, proximity, presence, size, speed, or any combination thereof) to a threshold value. In this way, certain types of measurements (such as motion from small animals) may be filtered out while other types of measurements (such as movement from a person walking) will be detected. In another embodiment, a similar methodology may be followed with a chemical sensor similar to or the same as chemical sensor  156 , for instance and without limitation as incorporated in detection unit  144 . A Chemical sensor may additionally or alternatively be powered on and upon detection of a substance of interest, may provide similar signals as motion sensor  120  configured to power the system as described below. In yet another example embodiment, a similar methodology may be followed with a particle sensor similar to or the same as particle sensor  152 , such as without limitation, a particle sensor incorporated in detection unit  144 . A particle sensor may additionally or alternatively be powered on, and upon detection of a substance of interest, may provide similar signals as motion sensor  120  or chemical sensor  156  configured to power the system as described below. Additionally, or alternatively, a real time clock and/or watchdog timer, which keeps track of time, may be used as a timer to power system and/or one or more units therein and/or components thereof on and off at predetermined times or intervals to perform a polling cycle, as discussed above with reference to  FIG. 1 . 
     Further referring to  FIG. 5 , at step  510 , if a triggering event has been detected such as when motion has been detected, particles have been detected, chemicals have been detected, and/or a predetermined time has elapsed or arrived then the system moves on to step  515 , otherwise step  505  is repeated. At  515 , a portion of the system at a second location of environment  108 , which may correspond to at least a portion of a sensor suite  148  similar or the same as sensor suite  148  is activated; for instance, and without limitation, at least a detection unit  144  may be activated upon receipt of a signal from entry unit  116 . Step  515  may include powering a portion of sensor suite  148  and arming constituent sensors. Arming of sensors at step  515  may also command those sensors to begin taking measurements. Arming of sensors may be irrespective of readings of any sensors, in other words, if a triggering event is detected at step  510 , a sensor suite  148  may start taking measurements with or without the presence of vaporized aerosols. 
     At step  520 , and still referring to  FIG. 5 , a particle count of environment  108  is measured by sensor suite  148  of detection unit  144 . Sensor suite  148  may be configured to detect a quantity, size, density, composition, structure, dispersion, or any combination thereof, of aerosolized particles in vaporized aerosol in a certain area similar or the same as environment  108 . In embodiments, sensor suite  148  may be configured to generate one or more signals including data representing quantity, size, density, composition, structure, dispersion, or any combination thereof of aerosolized particles. According to embodiments, these signals may be sent to another device and/or component such as communication hub  172 , one or more servers  112   a - c , a mobile device, or the like. 
     At step  525 , and with continued reference to  FIG. 5 , system  100  may be configured to determine whether a detection event has occurred. Determining whether a detection event has occurred may include determining a presence of substances  104  of interest in an area. Substances  104  of interest may include any substances  104  that may be a cause of concern for an area. For example, substances  104  of interest may include substances  104  that are disallowed in an area (such as nicotine, cannabinoids, tetrahydrocannabinoids, tobacco smoke, etc.), particles that are hazardous (carbon monoxide, arsine, hydrogen azide, hydrogen cyanide, nitrogen dioxide, viruses, bacteria, pathogens, etc.), undesirable particles for the area (tobacco smoke, nicotine, cannabinoids, tetrahydrocannabinoids, ammonia from pet excrement, etc.), or any combination thereof, to name a few. According to embodiments, determining presence of substances  104  of interest may include comparing, respectively by a unit and/or component of system  100 , such as without limitation an electronics stack  128 , entry unit  116 , detection unit  144 , communication hub  172 , and/or at least a server, a detected size, structure, composition, density, and/or dispersion to a threshold value. For example, a detected size exceeding a threshold value may indicate that substances  104  of interest are present in an area. 
     Further referring to  FIG. 5 , at  525 , system  100  may be configured to compare a quantity, particle density, and/or dispersion of detected substances  104  of interest to one or more predetermined threshold values in order to determine if a detection event has occurred. For example, system  100  may be configured to compare a detected particle density (such as from a cloud of aerosolized vape) to a threshold value and determine that the particle density has exceeded the threshold value indicating a detection event has occurred. If a detection event has occurred then the system moves to step  530 , otherwise the system repeats step  505 . 
     At step  530 , and continuing to refer to  FIG. 5 , an alarm signal is generated; the alarm signal may include a signal configured to induce an alert from an alarm. An alert may include an auditory alert or signal (such as a buzzer, siren, horn, etc.), a visual alert or signal (such as an LED, strobe light, laser, LED screen, LCD screen, etc.), tactile alert or signal (such as a vibration alarm, motor, etc.), or any combination thereof. 
     At  535 , and further referring to  FIG. 5 , an alarm signal may be transmitted to one or more servers (the same or similar as servers  122   a - c ) or a user device, and additionally stored; alarm signal may alternatively or additionally be generated on the one or more servers. An alarm signal may include data indicating that a detection event has occurred in the area and may be configured to display a particle count, density, size, composition, etc. as well as the area in which the detection event occurred on the user device. A user device may include a computer, a processor, a server, a smartphone, a tablet, a laptop, or any combination thereof, to name a few. In embodiments, a user may disable an alarm from a user device, whether that alarm was triggered by a detection event or a tamper event. 
     With reference to  FIG. 6 , a flow chart illustrating a method  600  for power distribution in an aerosolized substance detection system is presented. At step  605 , a trigger sensor, such as a motion sensor, particle sensor, chemical sensor, or the like, which may be similar or the same as motion sensor  120 , particle sensor  152 , or chemical sensor  156 , respectively, may be active. At step  610 , a trigger sensor may be configured to determine whether a triggering event has occurred. For example, a motion sensor may be configured to determine whether motion has been detected by detecting motion, proximity, and/or presence of one or more objects  124   a - b  within an area. Additionally, or alternatively, at  610 , a particle sensor or chemical sensor may be configured to determine if vaporized aerosols and/or chemicals are present within an area. In embodiments, detecting whether motion has been detected in an environment  108  may include comparing a detected motion, proximity, presence, size, speed, or any combination thereof to a threshold value. In this way, certain types of motion (such as from small animals) may be filtered out while other types of motion (such as from a person walking) will be detected. In another example embodiment, a similar methodology may be followed with a chemical sensor similar to or the same as chemical sensor  156 . A chemical sensor may be powered on, and upon detection of a substance of interest, may provide similar signals as motion sensor  120  configured to power the system as described below. In yet another example embodiment, a similar methodology may be followed with a particle sensor similar to or the same as particle sensor  152 . A particle sensor may additionally or alternatively be powered on, and upon detection of a substance of interest, may provide similar signals as motion sensor  120  or chemical sensor  156  configured to power the system as described below. Additionally, or alternatively, a real time clock, which keeps track of time, may be used as a timer to power the system on and off at predetermined times or intervals. 
     Further referring to  FIG. 6 , at step  610 , and in separate or the same example embodiments, if a triggering event such as when motion has been detected, particles have been detected, chemicals have been detected, and/or a predetermined time has elapsed or arrived then system  100  may move on to  615 , otherwise  605  may be repeated. At step  615 , a portion of the system  100  such as detection unit  144 , may be activated. In embodiments, activating a portion of system  100 , such as detection unit  144 , may include providing power to one or more sensors within sensor suite  148  from a battery  132  incorporated in detection unit  144 . In embodiments, power from battery  132  may be controlled and directed by a detection unit  144  electronics stack  128 . Electronics stack  128  and/or detection unit  144  may be configured to provide power to one or more sensors of the sensor suite  148  when motion, particles, chemicals, or in general, substances  104  of interest have been detected in the area. Further, in embodiments, electronics stack  128  and/or detection unit  144  may be configured to provide power from battery  132  to one or more components of electronics stack  128  and/or detection unit  144  in response to motion being detected in the area. 
     Still referring to  FIG. 6 , at step  620 , a particle count of environment  108  is measured by powered sensors within sensor suite  148 . Powered sensors may be configured to detect quantity, size, density, composition, structure, dispersion, or any combination thereof, of aerosolized particles in vaporized aerosol in a certain area similar or the same as environment  108 . In embodiments, powered sensors may be configured to generate one or more signals including data representing a quantity, size, density, composition, structure, dispersion, or any combination thereof of aerosolized particles. According to embodiments, these signals may be sent to a detection unit  144  electronics stack. 
     At step  625 , and with continued reference to  FIG. 6 , system  100  and/or any unit and/or element thereof may be configured to determine whether a detection event has occurred. Determining whether a detection event has occurred may include determining a presence of substances of interest  104  in an area. Substances of interest  104  may include any particles that may be a cause of concern in an area. For example, substances of interest  104  may include particles that are disallowed in an area (such as nicotine, cannabinoids, tetrahydrocannabinoids, tobacco smoke, etc.), particles that are hazardous (carbon monoxide, arsine, hydrogen azide, hydrogen cyanide, nitrogen dioxide, viruses, bacteria, pathogens, etc.), undesirable particles for an area (tobacco smoke, nicotine, cannabinoids, tetrahydrocannabinoids, ammonia from pet excrement, etc.), or any combination thereof, to name a few. According to embodiments, determining a presence of substances of interest  104  may include comparing, respectively by an electronics stack and/or at least a server, a detected size, structure, composition, density, and/or dispersion to a threshold value. For example, a detected size exceeding a threshold value may indicate that substances of interest  104  are present in the area. 
     Further referring to  FIG. 6  at step  625 , network is configured to compare a quantity, particle density, and/or dispersion of detected substances of interest  104  to one or more predetermined threshold values in order to determine if a detection event has occurred. For example, a system may be configured to compare a detected particle density of carbon di oxide to a threshold value and determine that the particle density has exceeded a threshold value indicating a detection event has occurred. If a detection event has occurred then system  100  moves to  630 , otherwise the system may cease providing power to the sensors and the system repeats step  605 . 
     At step  630 , and still referring to  FIG. 6 , power is provided from a battery to a transceiver within an electronics stack, such as without limitation an electronics stack of detection unit  144 . Transceiver may be configured to transmit and/or receive data from one or more servers the same or similar to servers  112   a - c  and/or a user device via, for example, internet, cellular networks, WIFI, Bluetooth, ZigBee, ethernet, wired connections, or any combination thereof. A user device may include a computer, a processor, a server, a smartphone, a tablet, a laptop, or any combination thereof, to name a few. 
     At step  635 , and with continued reference to  FIG. 6 , power is provided from a battery to an alarm. In embodiments, an alarm is configured to generate an alert or signal when power is provided and/or an alarm signal is received. Such an alert may include, but is not limited to, an audible alert or signal (such as a buzzer, siren, horn, etc.), a visual alert or signal (such as an LED, strobe light, laser, LED screen, LCD screen, etc.), tactile alert or signal (such as a vibration alarm, motor, etc.), or any combination thereof. 
     Referring now to  FIG. 7 , a graph  700  representing example sensor signals  708 ,  716 ,  720 ,  724 , and  728  and an example threshold  732  over particle count  704  vs time  712  is presented, according to an example embodiment. Graph  700  demonstrates an example particle count threshold that, when exceeded, may trigger an alarm and/or alert. According to graph  700 , it can be seen that sensor signals  708 ,  716 ,  720 ,  724 , and exceed threshold  732 . Conversely, sensor signal line  728  does not exceed threshold  732  and would therefore not trigger an alarm and/or an alert due to a detection event that has occurred.
