Motion detection

This sensor reacts to heat movements :  if a person, living being or object moves within its frame of observation, it detects it.

This is a sensor that returns an analog signal depending on a whole set of complex parameters : movement, temperature, speed, distance, etc. Each parameter isn't directly quantifiable, however all responses can be associated to the detection of a movement.

Even though they are part of the same group as the sensors used for automated garden lights, our version of the sensor is not a bang bang controller. This allows for extra possibility and subtlelty. One can choose the threshold value in the code combined with this sensor, in order to manage its sensitivity and range : a threshold much higher than the rest value will only be reached if the sensors detects close or big movements, whereas if the threshold is lower (or closer to rest value) means it shall react to all movement, even over a few meter.

Our sensor stands out from many other aumomated versions by functionning in real-time : it doesn't remain in an activated state for a few seconds after detection (which is the case and makes sense when switching on garden lights), having no detection latency, it reacts conitnuously and instantly.

Caracteristics :

  • Detection range goes up to 10 meters far.
  • Detection angle of 120°
  • One can adjust the range by facing the sensor more or less towards the ground.

  • One can reduce the angle by placing the sensor in a tube or behind an opaque cover.
  • External light or sunlight doesn't create interferences.

  • It has two M3 screw holes
  • The sensitive module can be separated from the rest of the card in order to fit into covers and be smaller and more discreet. The module and its card are then linked with an extra sensor extension cable. Please notify us by email if you wish for this option.

To process the data, the best way to analyse it is with two thresholds ie hysteresis control system (see in Programming section).

Please note, this sensor does not detect a fixed presence ! It only reacts to movement.
