Capacitive Touch Sensor (TTP223-B) optoelectronic With just a few linesThe touching detection is designed for replacing traditional direct button key. The sensor is essentially a button style sensor that detects when it is being pressed. One of the main differences is that it detects the presence of your finger on the sensor. This means that it doesnt require any force to activate the button. You can place the metallic pad under a non metallic surface such as a plastic or glass sheet and it will still work as a button,
