FIELD OF THE INVENTION 
       [0001]    The present invention relates to devices that provide information about their environment by means of electronic systems. 
       PRIOR ART 
       [0002]    Containers with electronic elements for drinking liquids, primarily geared toward temperature control, which contain a sensor element functionally connected to a controller that sends signals to an electric resistance to heat said liquid, preventing it from cooling, have been described in prior art. 
         [0003]    For example, U.S. Pat. No. 7,022,946B2 discloses an electronic container equipped with a temperature sensor that communicates with a heating element to keep a liquid hot, and a user interface attached to the upper portion of the container to input the desired temperature value. 
         [0004]    US patent 2010/0187298A1 discloses a container that contains an insertable electronic card that detects the liquid fill level and performs the collection process when a beverage is served in said recipient.

         [0005]    Accordingly, there is a need for the monitoring of chemical and physical characteristics of a liquid inside a container before ingestion, features that have not been disclosed in prior art. There is an equal need to provide a device that enables description of the mode of consumption in terms of the container&#39;s movement at the moment of drinking, and that also allows for transmission of information to external devices by means of wires and wirelessly.

         [0026]    For the purposes of the present invention, a container ( 2 ) is an item with any geometry that can contain liquids. In preferred embodiments, the geometry is preferably concave, such as a cup, a bowl, a mug or similar elements that serve the same function. 
         [0027]    For the purposes of the present invention, an embedded electronic device ( 3 ) is a device composed of hardware and software specifically designed and optimized to solve a specific problem in an efficient way. The term “embedded” refers to an electronic module housed by a larger system, that helps said system perform operations, such as processing data from the sensors, control of electric drives, information analysis, among others. 
         [0028]    Accordingly, the electronic system of the present invention is composed of a sensor element that receives a physical or chemical signal and converts it to an electric signal; a microcontroller that contains at least: an ADC module (Convertidor Análogo/Digital in Spanish), a UART serial communication module (Transmisor-Receptor Asincrono Universal in Spanish), an I2C communication module, to read the information transmitted by the sensor; a power-management element that supplies power to all of the elements of the system; and a wireless communication module that sends information to a platform hosted on a web server.

         [0030]    In a preferred version of the invention, the electronic, processing and communication systems are connected to an electric power supply, which can be an energy accumulator selected from the group that consists of: batteries, wireless charging devices understood to mean inductive charging devices, piezoelectric devices, or energy-harvesting devices, making use of renewable sources of energy such as sunlight. 
         [0031]    For the purposes of the present invention, the embedded electronic system contains a central processing or microcontroller unit, a power-management module, the sensor elements and data transmitter-receiver or transceiver. 
         [0032]    In a preferred version of the present invention, signal transmission is performed by means of wireless communication, using a communication protocol selected from the group that consists of: IEEE 802.15.4, Zigbee, 6LowPan, Bluetooth, wifi, cellular network, Ant+. In other versions, said means of communication can also be wired, in which case the protocol used is selected from the group that consists mainly of: USB and stereo plug.

         [0033]    In another aspect of the present invention, the device of the present invention possesses an interface that shows information related to the characteristics of the liquid in the container ( 1 ) and to the use and consumption habits of the liquids in the container ( 1 ). 
         [0034]    This allows for characterization of the quantities of substances ingested in a given time period, the time it takes to ingest them, and description of the movement used to do so. 
         [0035]    In another aspect of the present invention, the electronic container also contains a device that produces sound or vibrates in connection with the signals transmitted by one of the controllers, to inform the user about patterns of the liquid to be drunk or of the movement used to ingest it.

         [0040]    The device was equipped with sensors to measure the color intensity of two different commercial cola beverages, before their ingestion. The invention incorporated a wireless WIFI communication module under the 802.11 standard, in order to wirelessly transmit data obtained by the sensor, a microcontroller to read the data from the sensor, process them and transmit them to the wireless communication module for the purpose of communicating with a web platform hosted on a server in the cloud. In the case of the sensor, it provides digital (in I2C, serial, one wire protocols) or analog information, which is interpreted by the microcontroller by means of an analog-digital converter (ADC) module contained within it. 
         [0041]    As a power source for the invention, including the wireless transmission module and the color sensor, two functionally linked AA batteries with a DC/DC boost converter were utilized in order to provide the system with a general power supply voltage of 3.3V. 
         [0042]    The environmental conditions (temperature, pressure and ambient light) that were manipulated for capturing color data for both beverages were identical. 
         [0043]    The following time-intensity curves obtained as a result show the intensity of the color of the beverage contained in the cup over time, measured in milliseconds. 
         [0000]    Color Intensity 

 
         [0044]    As a result of this example, we conclude that both cola beverages possess differences in color intensity, having measured different intensities for the color red in both beverages, by means of which a user could detect these differences before drinking it, or even characterize an unknown type of beverage, using the present invention. 
         [0045]    It must be understood that the present invention is not restricted to the modalities described and exemplified herein. As is evident to a person versed in the art, there are other possible variations and modifications that do not deviate from the spirit of the invention, which is only defined by the following claims:
