This low power device uses a Doppler radar module is used to detect motion and can even be used to measure the speed of a moving object. It also has the ability to detect objects behind walls and other obstacles which makes it an excellent option for projects that involve security, door control and more.

It measures frequency changes by continuously emitting a constant signal at a frequency of ~10.5 GHz and detecting the microwave frequency of the moving object.

SMAKN HB100 comes with a long detection range and has the following specifications:

  • Length: 32mm
  • Width: 45mm
  • Height: 8mm
  • Detection range: 20m
  • Supply voltage: 4.75- 5.25V
  • Current: 30mA
