Principle Introduction:
Winsen Electronics, develops and manufactures pir motion sensor, human body induction sensors for lighting and home safety field by using the temperature-dependent feature.
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 :
Safety Alarm
Electricity Lighting
House-hold and other fields
