CAP1188 8 Key Capacitive Touch Sensor Module SPI I2C Captouch LED 8 Button Key 3V-5V Geekcreit for Arduino - products that work with official Arduino boards

Description: Add lots of touch sensors to your next microcontroller project with this easy-to-use 8-channel capacitive touch sensor break out board, starring the CAP1188. This chip can handle up to 8 individual touch pads, and has a very nice feature that makes it stand out for us: it will light up the 8 onboard LEDs when the matching touch sensor fires to help you debug your sensor setup.Comes with a fully assembled board, and a stick of 0.1" header so you can plug it into a breadboard. Using this chip is a lot easier than doing the capacitive sensing with analog inputs.The CAP1188 has support for both I2C and SPI, so it 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. Specifications: 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 Package Included: 1 x CAP1188 8 Key Capacitive Touch Sensor 2 x Pin Header
