TTP223B Capacitive Touch Switch Digital Touch Pad Sensor Module For Arduino

The TTP223B is a touch pad detector IC which offers 1 touch key. The touching detection IC is designed for replacing traditional direct button key with diverse pad size. Low power consumption and wide operating voltage are the contact key features for DC or AC application. In the normal state, the module output low, low power consumption; when a finger touches the corresponding position, the module output high, if not touched for 12 seconds, switches to low-power mode.
