INTRODUCTION

This arduino digital capacitive touch sensor provides a one-touch style switch on your Arduino project. It uses the most popular capactiive sensing technology which is the same as your mobile phone. 

Getting tired with clicking mechanic button? Try this capacitive touch sensor. Right now we can find touch sensor on most electronic device. So upgrade your Arduino project with our new version touch sensor and make it cool!!

To ease the difficult of using this sensor,  a Gravity Interface is adapted to allow plug&play.  The IO expansion shield is the best match for this sound senor connecting to your Arduino. As this sensor can work at 3.3V which make it compatible with Raspberry Pi, intel edison, joule and curie. 

If you want to start playing with sensors, Gravity: 27 Pcs Sensor Kit for Arduino is a great choice for you to learn varieties of sensors.
