You can find touch sensors mostly on electronic device. Instead of buttons, upgrade your Arduino project with our new version touch sensor and make it cool!
The EASY Plug digital capacitive touch sensor provides a one-touch style switch on your Arduino project. It uses the most popular capacitive sensing technology which is the same as your mobile phone.
This little sensor can "feel" people and metal touch and feedback a high/low voltage level. Even isolated by some cloth and paper, it can still feel the touch. The sensitivity will decrease as the isolation getting thick.
This module should be used together with EASY plug control board.
