This is HOME AUTOMATION TOUCH PAD 7-Way Capacitive Touch Switch Digital Touch Sensor Keypad Module.

This capacitive touch sensor module uses the HOME AUTOMATION TOUCH PAD integrated circuit, making it easy to add capacitive touch input to your project. It features 7 sensitive touch pads that make an ideal replacement for the old fashioned keypads.

Capacitive touch allows electronics to sense when your finger is within a few millimetres of a surface to simulate a button “press” just like how the pushbutton works. Capacitive sensing may be used in any place where low to no force human touch sensing is desirable.

This is a 16 switch based easy to use capacitive touch sensing module, This 7 switch digital touch sensor module is based on a touch sensing IV HOME AUTOMATION TOUCH PAD. This device has a built-in regulator for the touch sensor. We can add interfaces through the non-conductive dielectric material.
