Summary:

Digital PIR sensor RDB224, 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.

Feature:

* Delay time adjustable

* High-precision AD signal process

* Differential signal input mode, anti-interference ability

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

* Digital TTL signal output
