PASSIVE INFRARED SENSOR

Working Principle
  • A PIR Sensor is a Passive Infrared Sensor which controls the switching on/off of the lighting load when it detects a moving target.
  • The built in sensor turns on/off the connected lighting load when it detects motion in the coverage area. It has different working principle during the day time and the night time.
  • During the day, the built in photocell sensor saves electricity by deactivating the lighting load connected to the sensor.
  • During the night the connected lighting load is turned on by adjusting the luminosity knob (LUX).
