This article explains an upgraded smart solid-state AC switch system that uses microwave Doppler radar instead of traditional ...

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 ...

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 ...

When you can package a radar system in a 10- × 10-mm chip, you end up with a new type of sensor that was unimagined a few years ago. Today, it’s becoming common practice to use a radar chip for some ...

A 24 GHz Demorad radar solution to support contactless sensors is being used in the emerging industrial mass market. 24 GHz, silicon-based mmWave radar technology is enabling a new generation of ...

Alphabet Inc’s Google unit won approval from US regulators to deploy a radar-based motion sensing device known as Project Soli. The Federal Communications Commission (FCC) said in an order late on ...

The first automobile driver ever fined for speeding was Walter Arnold in England’s Kent County, circa 1896. Arnold, a Benz dealer, got caught going approximately 8 mph, well over the 2-mph limit for ...
