Capacitive Touch Sensor is a very useful addition for projects or applications where a conventional mechanical button or switch is not an ideal choice. This is a simple to use Capacitive Touch Module. It has a digital output which outputs a low signal(0V) by default, and outputs a high signal(5V) whenever you touch the module with your finger. This makes it easy and simple to connect it to an Arduino, Raspberry Pi or any other microcontroller. It can be used in place of a switch to provide inputs to a microcontroller.
Module can be installed behind surfaces such as plastic, glass and non-metallic materials and the button press can still be detected
