AM312 human body induction module is a digital intelligent automatic control product based on passive human infrared technology, which has high sensitivity and strong reliability, and is widely used in various automatic induction electrical equipment. Schematic diagram and typical application
technical parameter1. working voltage: DC 2.7-12V;2. static power consumption: less than 0.1mA;3. delay time: 2 seconds;4. lock time: 2 seconds;5. trigger mode: repeatable;6. induction range: less than 100 degrees angle, 3-5 meters; (according to the specific lens)7. operating temperature: -20C-+60C centigrade8.PCB size: 10mm*8mm9. module lens: small lens Functional characteristics The anti-interference performance is enhanced, and the internal digital signal processing is used to directly output the high and low level.Repeatable trigger mode: induction output high level, the delay time period, if the body is in its sensing range, the output will always maintain a high level, until the people left after the delay, was changed into low level (i.e., each activity induction module detects human body will be automatically postponed to the next a delay time, and delay starting point to the last active time).
