Description:
The TTP223B Digital Capacitive Touch Sensing Module is a capacitive touch switch based on a touch sensing IC (TTP223B).
When touched the modules output switches to HIGH and if not touched for 12 seconds switches back to LOW.
The TTP223B Touch Sensing Module in its normal state the output is LOW.
