Principle Introduction:
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 dual 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.
Applications :
Human body detection lighting;
Auto control door, toys, switches;
Anti-crime devices: security camera, alarm;
Home Appliance;
