BS412 Pyroelectric Infrared Sensor
BS412 pyroelectric infrared sensor integrates the digital intelligent control circuit and the human body detection sensitive element in an electromagnetic shield. The human body detection sensitive element will sense the human body movement signal through the very high impedance differential input circuit coupled to the digital intelligent integrated circuit chip, the digital intelligent integrated circuit will be converted into ADC digital signals, all the signal processing is completed on the chip. PIR sensors are low-power, small, easy to used. For this reason it can be used for the alarm system and lighting control.
