RDB226-S Digital Pyroelectric Infrared Sensor
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
Applications
