YS312 Pyroelectric Infrared Sensor
YS312 is a type of PIR sensor which integrates AD chip and sensitive element in a hermetically sealed package.The sensitive element transmits the sensed human body movement signal to the AD chip, which outputs 16-bit digital signals through collection, filtering, etc., and realizes related functions through the peripheral circuit MCU. PIR sensors are low-power, small, easy to used. For this reason it can be used for consumer electronics applications, smart home/security applications and lighting applications
