TTP226 8-way Capacitive Touch Key Digital Sensor Module Board
Add lots of touch sensors to your next microcontroller project with this easy-to-use 8-channel capacitive touch sensor breakout board, starring the TTP226.
This chip can handle up to 8 individual touch pads, and has a very nice feature : it will light up the 8 onboard LEDs when the matching touch sensor fires, to help you debug your sensor setup.
Working Power : 2.4-5.5V
PCB Board Size : 47 x 46mm/ 1.9" x 1.8" (L*W)
Net Weight : 5g
This sensor is a toggle output type: touch-on then touch-off. That means that when a capacitive load is detected (e.g. a person touches the sensor-pad area) the red LED will alternate turning off and the output pin will go high or low, respectively. This sensor has 8 such touch pads.
