After some searching, I ended up using a microcontroller and a piece of code borrowed from the web that I tweaked and adapted. The microcontroller-based concept was chosen because I wanted to scale ...

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.

The sensor operates at 5V for Arduino and 3.3V for Raspberry Pi, ensuring seamless integration with these popular microcontroller and microcomputer platforms.

The CY3280-MBR3 CapSense MBR3 kit can be used to evaluate the third generation of Cypress Semiconductor’s capacitive-sensing technology. Likely applications are button designs and proximity sensing.

Instead of measuring light, we measure the ambient voltage field on pin A5 and use it to detect if someone is too close to our Arduino. A5 is used as a “floating input”, but unfortunately it is very ...
