Overview
Digital PIR sensor SMC334-W, is an integrated design of sensitive element and signal processing chip, packaged sensitive element and IC chip into sensor shield. Sensitive element transfer the human movement signal to high-precision digital chip by differential input for data processing. Then the sensor gives digital signal for easy using.
