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.

This little sensor can “feel” people and metal touch and feedback a high/low voltage level. Even isolated by cloth or paper, it still can feel the touch. The sensitivity will decrease as the isolation getting thick. For detail of usage, please check it’s wiki.

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

Features:

• Wide voltage range from 3.3V to 5V
• Standard assembling structure (two 3mm holes with multiple of 5 cm as interval)
• Easily recognitive interfaces of sensors (“A” for analog and “D” for digital)
• Icons to simply illustrate sensor function
• High quality connector
• Immersion gold surface

Specification:

• Supply Voltage: 3.3V to 5V
• Interface: Digital
• Size:22x30mm (0.87 x 1.18 in)
