TTP224 4-Channel Touch Sensor Module
The TTP224 is a 4-Channel Touch Sensor, meaning it has four touchpads. Whenever a capacitive load such as human hands is brought in proximity with the sense pad, the sensor then senses 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. Each Touchpad has its respective output pin when the user touches a pad, the corresponding output pin will go high. It is very easy to interface with microcontrollers like Arduino to control different applications as a switch. It can be used in home automation, motor control, Relay control, etc. the module basically gets rid of the push button troubles.
