Description:
This Capacitive Touch Module is a 4 pad touch detector, which is based on TTP224 touch sensor chip. Each pad is connected to an input of the TTP224 chip, parallel with a capacitor. This chip has 4 capacitive sensing inputs, which each capacitor can change by its touched pad and change its input level. Because of applying these capacitors, it's known as capacitive touch sensor or chip.
This module develops your project to a capacitive touch pad project. This touch module is supplied with 2.4 to 5.5VDC and activate its touch pad sensor, which  is compatible with all Arduino boards 3.3V/5V and microcontroller.
When the pad touching occurs, the sensor detects the capacitance level shifting and activates the switch. Common touching can be a nearly any conductive material and also through thin layers of non-conductive materials such as glass, plastic, fabric or even wood. This module has 4 pads, so 4 input switch, and  4 output pin (OUT1 - OUT4) with normally 0V level ("LOW"), which shifts to VCC ("High") while touching the pad.
