This is a CAP1188 8 channel Capacitive Touch Key Sensor Module with SPI or I2C interface and onboard 8 touch state indicator LEDs. Its operates 3.3/5v so it is suitable for arduino.
The CAP1188 has support for both I2C and SPI, so it is easy to use with any microcontroller. If you are using I2C, you can select one of 5 addresses, for a total of 40 capacitive touch pads on one I2C 2-wire bus. Using this chip is a lot easier than doing the capacitive sensing with analog inputs: it handles all the filtering for you and can be configured for more/less sensitivity.
Specificatoins of CAP1188 8-Key Capacitive Touch Sensor Breakout:
- Capacitive touch sensor
- Requires soldering of header pins
- Perfect for Arduino project
- Comes with a fully assembled board, and a stick of 0.1" header so you can plug it into a breadboard.
- It Supports I2C and SPI communication protocol
- Sensor Type: Capacitive Touch
- Sensing range: 8 button / key interfaces
- Sensitivity: I2C, SPI
- Voltage - Supply: 3 V ~ 5V
- Material: Plastic
- Size: Approx.40*18*4mm
