Pyroelectric Infrared Sensor detects the infrared radiation by using the temperature-dependent feature.
It suppresses the interference caused by temperature change, adopts the method of quad sensing elements complementary which improves the stability of the sensor.
This PIR sensor can be widely used in safety device, burglar alarm, automatic door, auto light control and intelligent toys.

Application

Security, Intrusion alarm, Indoor access management;
Human body detection lighting;
Auto control door,smart home;
Smart office appliance;

Features

High sensitivity and excellent signal to noise ratio
Excellent immunity to interference
Strong anti-white light ability
Adopting quad-element compensation structure, to resist external environmental interference
