<b>Description</b><br><br> PIR(Passive infrared) Motion sensor is pyroelectric device can detect human movement by detecting Infrared ray emitted by human body. Operating voltage is 5~25VDC, and output voltage is equal to input voltage. High sensitivity, Easy to install. <br> <b>Automatic Induction</b> <br> <br> When people enter into the sensing range, Motion sensor will output a voltage equal to input voltage, after the delay time, it will output 0V; During the delay time if motion detected, the delay time will reset, and start a new delay time. <br> <b>Application</b> <br> <br> Widely used on the Motion-activated lighting, LED strips Security System, automatic sensory device and more. <br>< <b>Specification</b> <br> <br> Passive Infrared Sensor <br> Operating voltage DC: 12V<br> Load current : 3A <br> Delay time: Default setting 5-25s (2~280 Seconds adjustable)<br> Detecting range ≤ 110 degrees cone angle <br> Detecting distance4M-7M (10cm-7M adjustable) <br> Trigger way : Continuous triggering <br> Blockade time: 0 seconds <br> Size: 48*25*14 mm <br> Delay time adjustment: Clock-wise reduce the delay time , Anticlockwise increase the delay time <br> Sensor distance adjustment: Clock-wise increase the Sensor distance, Anticlockwise reduce the Sensor distance <br><br> <b>Note: </b> <br> <br> 1. The PIR Sensor requires a 'warm-up' time in order to function properly, about 10 s to1 min, depending on the delay time; during this time, the signal triggered by the module is not stable, after one minute, it will be ready. <br> 2. Don't expose the Sensor Switch to direct sun light /lighting, big wind, or placing near to a heater or air condition. <br> 3. Don't fix the item at a place where there are obstructing material (eg. Glass, dense clothes) which IR cannot get though. <br> 4. Don't fix the motion sensor switch in strong shock or vibration environment. <br>
