100% Original Digital Smart Pyroelectric Infrared Radial Sensor (AM312)
AM312 is a new digital intelligent PIR sensor.This Smart digital detector offers a complete motion detector solution,with all electronic circuitry built into the detector housing. Only a power supply and power-switching components need to be added to make the entire motion switch.
Features and Benefits:
1. Digital signal processing(DSP)
2. Two-way differential high impedance sensor input and temperature compensation
3. Built-in filter, screen the interference by other frequency
4.Schmidt REL output
