The module is 4 channel capacitive analog touch sensor module.

The larger number area you touch, the higher voltage it output. If you supply 5V power for it, the output voltage is:

when there is no active touch, it is about 0V.

when you touch NO.1 area, it is about 1V.

when you touch NO.2 area, it is about 2V.

when you touch NO.3 area, it is about 3V.

when you touch NO.4 area, it is about 4V.

It works at single key mode, so it will only detect one key if you touch more than 1 area at the same time.

It can be installed under various non-metallic materials, such as plastic, glass, acrylic plate.
