CAPACITIVE TOUCH MODULE 4 CHANNEL

To add a capacitive touch sensing feature to your project, get this Capacitive Touch Module with IC TTP224. This sensor is 2.4 - *****C powered. All you need to do is to touch the pad. Its touch switches easily interfacing any of your project with or without the presence of your microcontroller.

How does it work? The switch is activated as it sense the change in capacitance. Change in capacitance happens in sense-pad closeness of a capacitive load which is your hand. Any conductive material can be your customized sense-pad as this sensor detects touch sensitivity via non-conductive material's thin layers like fabric, glass, wood or plastic. Avoid typical push-buttons troubles by hiding this sensor in the wall, tabletop, etc.

Enjoy this module for your project with a total of 4 sense-pads extendable by most of conductive materials or simply wires.
