Oiyagai 2pcs AM312 Mini Pyroelectric PIR Sensor Module Manual Motion Infrared IR Detector

Type: Repeatable Infrared sensor: dual element, low noise, high sensitivity. Anti interference is enhanced, the internal use of digital signal processing, output the high level and low level directly. 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, it change to low level every activity of human body induction module detects automatically postpone a delay time, and delay starting point to the last active time. Application: Widely automatic induction electrical equipment, such as alarm detector, light switch, motion light, intellectualized toys or appliance, security system etc.
