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.
16-bit digital signal output
Single-wire serial data
Low power consumption
