Infrared motion sensor (passive)
For surface mounting
IP44
Automatically, temporarily turns on the lighting in the event of the appearance of a person or other object in such places as corridors, courtyards, approaches and driveways, garages, etc.
The infrared motion sensor works by detecting the movement of heat sources that are within its area of operation.
The effectiveness of detection is affected by:
- the amount of heat emitted by the moving object and the ambient temperature,
- the size of the moving object,
- the direction and speed of the movement.
The effectiveness of an infrared motion sensor will be lowest when:
- the temperature of the moving object is close to the ambient temperature (e.g., a sunny room, a radiator in the detection field, etc.),
- the object is moving at a low speed directly towards the motion sensor,
- the size of the moving object will be small compared to the area of the detection zone.
Examples of situations that can lead to malfunction of infrared motion sensors:
- Light sources located in the detection area of the PIR motion sensor. Turning a light on/off causes a large and rapid change in the temperature of the bulb, which can be interpreted by the infrared motion sensor as a moving object.
