Comparison of Capacitive with Induction Sensors. Capacitive sensing involves charging up plates, so it is somewhat slower than inductive: 10 to 50 Hz, with a sensing distance from 3 to 60 mm.

The sensor package comprises an ultrasonic distance sensor, a microcontroller running Arduino firmware, a micro-SD card for datalogging, a real-time clock for timekeeping and sleep functions, and an ...
