I recently picked up a couple of microwave motion sensor radar modules. You have seen (and perhaps tried) it before. This post is about the HFS-DC06 (DC5V/5.8GHz) Microwave Radar Sensor Switch Module!
Last year, I took a look at some mostly low-cost passive infrared (PIR) motion sensor modules. Then recently, I became more aware of cheap microwave radar motion sensor modules. The popular version of ...
Imec has made a millimetre-wave motion detection radar at 60GHz, integrated in standard 28nm CMOS. Achieving 2-cm range resolution, the ultra-sensitive radar is optimized for vital sign monitoring and ...
