Product Details 产品规格书下载

Digital PIR sensor RDB226-S, 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.

Features:

* High-precision AD signal process

* Differential signal input mode, anti-interference ability

* Sensitivity, delay time, and light adjustment function

* Enable pin controls the sensor output

* Wide voltage power supply(1.5~4.5V) and power consumption

* Digital TTL signal output
