Overview
This 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.
Feature
16-bit digital signal output
Signal-wire serial data
Low power consumption
