RDB223 Digital Pyroelectric Infrared Sensor

Available:In Stock
R$ 6,90

Application:Security product,Human body induction toys,Human body induction lamps, and switches
Feature:High-precision AD signal process,Differential signal input mode, anti-interference ability.

Production Description:
Digital PIR sensor RDB223, 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 for data processing. Then the sensor gives digital signal for easy using.
