Detection using today’s microwave sensors has some advantages. Unlike traditional passive infrared motion sensors, most microwave sensors can distinguish between moving and static objects, and objects ...

Your garden variety motion detector uses IR, but these days, there are fancier technologies for achieving similar goals. If so desired, you can source yourself a microwave-based presence sensor ...

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 ...
