Digital capacitive touch keypad module

Model: TIP224.
Digital capacitive touch keypad module.
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.
Features:
Operating voltage: 2 V - 5.5 V.
Startup calibration delay: 0.5 sec.
Output status indicator LED.
Output can be configured be active high or low
Output mode can be configured to toggle or momentary
Output can be directly connected to microcontroller's input pins.
Based on TTP224.
