DFR0030

This Arduino digital capacitive touch sensor provides a one-touch style switch for your Arduino project. It uses the capacitive sensing technology which is the same as your mobile phone. This little sensor can detect a touch and feedback a high/low voltage level. Even insulated by cloth or paper, it can still detect the touch but the sensitivity will decrease as the insulation gets thicker.

• Wide voltage range from 3.3V to 5V
• Standard assembly structure (two 3mm mounting holes with multiple of 5mm as interval)
• Feeds back high/low voltage level
• Digital interface
• Plug and play 3-pin Gravity interface
• Board size: 22x30mm
