Infrared Pyroelectric Sensor RDB224
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
APPLICATION
Human body induction empower home appliances with intelligence.In the field of human body induction, the main application fields of Winsen sensors are toys, burglar alarms, induction doors, induction lamps, induction switches, etc.
The infrared alarm to prevent human intrusion is composed of pyroelectric infrared sensor and alarm controller. When someone enters the range to be protected, the sensor generates an electrical signal and transmits it to the controller, and the controller sends the alarm signal to the terminal through signal processing.
