mmWave RADAR Sensor Primer

I have been using several microwave motion sensor doppler radar modules for years, but in cases where an ultrafine movement detection is demanded, those cheapo modules did not perform well. So I decided to have […]

Overheat Sensor Arduino Siren

Not long ago, I played around with making an overheat sensor siren on the Arduino Uno, which I later modified a bit and incorporated into another hobby electronics project. Needless to say, it worked fine. […]
