A Millimeter wave motion sensor for home automation, rather small at 44x22mm.
This motion detector uses microwave radar to detect the presence of a person, instead of heat like in passive infra red sensors. The beauty of mmwave sensors is they can detect you when you’re stationary (they detect the small movements of your chest from breathing), so no more waving hands when the lights turn off on you.
