This device allows you control a switch trough touch the module, it can be applied into smart home system When your finger touch the “touch area ”of this module, the “s”pin can output a high level signal to your microcontroller like Arduino to respond different action. Touch sensor technology offers tremendous benefits over the mechanical switch components traditionally used in interface controls Manually creating or modifying the complex, intricately shaped touch sensor electrodes in a PCB design can be an arduous task However, using an automated approach when creating or modifying capacitive touch sensor.

The controller is connected to a simple capacitive touch sensor, which is just a copper pour separated from the ground plane by a thin keepout zone, forming a capacitor Whenever something, such as a finger gets near to, or touches the sensor, it changes the capacitance, which is sensed by the touch controller, which outputs a signal. Capacitive touch sensor interfaces can be incorporated into products with curved surfaces allowing for greater design flexibility No moving parts allow for increased durability and reduce the number of components It provides a smooth, sleek appearance without raised surfaces or button openings allowing for ease of cleaning and sealed designs. Capacitive touch buttons, sliders, wheels (Zero or One dimensional sensors) These applications use mostly selfcapacitive sensors, because they are simpler to be implemented and provide accurate and robust performance regarding touch detection.
