Overview

The YS312K is a pyroelectric infrared sensor that integrates both the AD chip and the human body detection sensor in an electromagnetic shielding housing. The human body detection sensor transmits the sensed human body movement signal to the AD chip, which outputs 16-bit digital signals through acquisition, filtering, etc., and realizes relevant functions through the single-chip microcomputer of the peripheral circuit.


Feature

16-bit digital signal output

★ Single-wire serial data

★ Low power consumption
