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.

You can use any resistor value between 100-kilo-ohm and 50-mega-ohm. Note that at higher resistor value, it behaves like a proximity sensor. The circuit requires a capacitive sensor library in Arduino ...

One of the most overlooked or forgotten proximity sensors on the market today is the capacitive sensor. Capacitive sensors are suitable for solving numerous applications. These sensors can be used to ...

Capacitive proximity sensors include the measurement of human interference. Humans generally have a fixed coupling to earth. The device has a variable coupling to earth (in hand versus on table).

The microcontroller-based concept was chosen because I wanted to scale the sensor system later to suit other applications. Here is the diagram of my Arduino infrared close proximity sensor. As you can ...
