Overview

These breakout boards are a simple way to add capacitive touch to your project. Just power

with 1.8 to 5.5VDC and touch the pad to activate the sensor. These touch switches interface

easily to any project - with or without a microcontroller.

When a capacitive load (such as a human hand) is in close proximity to the sense-pad, the

sensor detects the change in capacitance and activates the switch. Custom sense-pads can

be made form nearly any conductive material and these sensors can detect touch through

thin layers of non-conductive materials such as glass, plastic, fabric or even wood.

The breakouts come in three styles:
