Simply put, unlike passive infrared sensors which detect objects by sensing changes in naturally emitted infrared, this active infrared close proximity sensor drives an infrared emitter to illuminate ...
The sensor shown here is essentially two plates mounted side-by-side, attached to an Arduino Nano using the Capacitor library which uses just two pins, one digital and one analog.
I've just come across a no-name non-contact, high-precision 80 GHz mmWave radar sensor for liquid level detection with a 40m ...
