The microwave radar module and the motion sensor - differences

The capabilities of microwave radar modules based on an electromagnetic wave are much greater than that of standard motion and distance sensors, which can only detect the presence (e.g. of a human) by detecting large body movements. The microwave sensor, in turn, is very sensitive, thanks to which it can detect the presence of a human even after the slightest movement - it reads micromovements, such as breathing or finger movement.

Precautions

  • Avoid aiming the sensor directly at the air conditioner, curtain, fan or other installation, as the swaying and movement of these objects may distort the measurements and erroneously detect motion.
  • Pay attention to multiple reflections - especially mirror images, which also interfere with the measurement.
  • Proper configuration of parameters such as maximum detection distance, sensitivity and delay time can exclude some objects from the observation zone.
  • When installing several modules at the same time - remember to keep a minimum distance of 1.5 m between them and place them parallel to each other.
The detection area can be adjusted by the tilt of the module.

The detection area can be adjusted by the tilt of the module.
