The Story
The Grove Touch Sensor enables you to replace the press with touch! The sensor measures the capacitance of a metallic pad and detects the change in capacitance when a finger is nearby. The module is based on the TTP223-B touch detector IC.
This is the same technology used in the iPhone touch screen. You can place the metallic pad under a non-metallic surface such as a plastic or glass sheet and it will still work as a button, which is useful for projects that have to be waterproof.
With the help of the touch sensor, you can also make a secret button by placing it inconspicuously behind a smooth surface. For instance, you could place them under a nonmetallic card table and by casually pressing the right location on a tabletop surface you could mysteriously control your DIY project!
