TTP223 Based Capacitive Touch Sensor Module

This is a digital capacitive touch switch based on TTP223B touch-sensing IC. The module works as a switch and replaces a traditional push-type key.
Module generally outputs low and keeps at low power state. When a touch is sensed on the circular marked region, it outputs high and switches to the quick response state. When not being touched for 12 seconds, it switches to low power state again. The module can also be used to hide touch keys behind walls and desks.
The module can be interfaced with any microcontroller or an arduino or even without one. When a capacitive load (such as a human hand) is in close proximity to the sense-pad, the sensor detects the change in capacitance and activates the switch. Custom sense-pads can be made from nearly any conductive material and these sensors can detect touch through thin layers of non-conductive materials such as glass, plastic, fabric or even wood.
