From Micro Ohm's description

TTP226 8-way Capacitive Touch Switch Module The TTP226 is a touchpad detector IC which offers 8 touch key. The touching detection IC is designed for replacing the traditional direct button key with a diverse pad size. 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. Note : HW-137 on board working remains same . Features of TTP226 8-way Capacitive Touch Switch Module: On-board TTP226 capacitive touch induction IC On-board 8-way level indicator. Adjustable output mode, key output mode, longest time and fast/low power output. Package Includes: 1 x TTP226 8-way Capacitive Touch Switch Module.
