Are you tired with clicking mechanic button? Try our 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!!
This little sensor can "feel" people and metal touch and feedback a high/low voltage level.
Wide voltage range from 3.3V to 5V
Standard assembling structure (two 3mm holes with multiple of 5cm as interval)
Easily recognitive interfaces of sensors ("A" for analog and "D" for digital)
High quality connector
1 for Power + VCC
2 for output OUT
3 for power - GND
Specification
Supply Voltage: 3.3V to 5V
Interface: Digital
Size:22x30mm
