Microwave Detectors VS PIR

Microwave sensor vs pir


  • Microwave presence detectors are sensitive to movement and are ideal for large spaces and areas that have an awkward shape or where fine motion detection is required.

  • Microwave detectors have a much greater coverage and higher sensitivity and can detect movement through glass. Careful consideration needs to be given to the location of microwave sensors.PIR-Detection

  • PIR (Passive Infra-Red) presence detectors detect body heat and movement and are ideally suited to smaller spaces or where a defined detection pattern is required such as:
    • Offices
    • Boardrooms
    • Bathrooms & Toilets
    • Copier Rooms

    There Are Certain Specific Differences Between The Microwave Sensors And The PIR Sensors:

    • Generally, microwave sensors have much better sensibility compared to the PIR sensors.
    • Microwave sensors can also perform well if there is any metalloid barrier, which the PIR sensors cannot.
    • Moreover, the sensibility of PIR sensors is also compromised if the ambient temperature is more than 35ᵒ Celsius.
