Protocentral FDC1004 capacitance sensor breakout board

FDC1004 Breakout

If you don't already have one, you can buy the ProtoCentral FDC1004 breakout board from:

The FDC1004 is a single-chip IC for capacitance measurement for application including proximity sensing and liquid level sensing. This is based on the concept of measuring capacitance of an electrode with respect to ground.

This breakout board contains everything to connect it to an Arduino's I2C pins and it can be connected to any other platform with support for I2C two-wire interfaces.

We have made several cool projects with it including proximity sensing and liquid-level sensing from the outside of a tank. Check out our Hackster page for the detailed project description.
