YS312 Pyroelectric Infrared Sensor
The YS312 is a pyroelectric infrared sensor that integrates an AD chip and a human detection sensing element within an electromagnetic shielding cover. The sensing element detects human motion signals, which are then transmitted to the AD chip for acquisition and filtering, ultimately outputting as a digital signal. It is specifically designed for human motion detection applications.
