PIR sensor detects the infrared radiation via the characteristics of the temperature change. By the complementation of two sensitive unit, the unit restrains the interference caused by temperature variation and improve the working stability of the sensor.
Feature
* High sensitivity & superior SNR
* High stability to temperature variation
* High EFT(vibratio,radio-frequency interference, etc)
* High cost performance
Application
1.Security
2.Luminaire
3.Domestic appliance
