Electric heat scattering infrared sensor detects the infrared radiation by using the temperature-dependent feature. It suppresses the interference caused by temperature change adopting the method of two sensitive elements complementary which improves the stability of the sensor. The sensors can be widely used in safety device, burglar alarm, automatic door, automatic lighting, toys, etc

 

Features                                                 

 

* High sensitivity and excellent signal to noise ratio

* High temperature-dependent stability

* Strong anti-jamming ability (e.g. vibration, radio-frequency interference etc.) 

* High value with competitive price

 

Application

1. Safety

2. Electricity Lighting

3. House-hold and other fields
