Project – RED TTP223 1 Channel Capacitive Touch Sensor Module

A capacitive touch sensor module based on the dedicated TTP223 touch sensor IC. The module provides a single integrated touch sensing area of 11 x 10.5mm with a sensor range of ~5mm. An onboard LED will give a visual indication of when the sensor is triggered. When triggered the module’s output will switch from its idle low state to high (default operation). Solder jumpers allow for reconfiguring its mode of operation to be either active low or toggle output. The TTP223 touch sensor module can be easily used with microcontrollers like Arduino to act as a touch input.
