This is a simple touch sensor module. You can use it to replace a traditional push button.

Using the TTP223-B touch detector IC it measures the capacitance of a metallic pad. It can detect the change in capacitance when a finger is near it. This is the same technology used in the iPhone touch screen.

So 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. This may be useful for projects that need to be waterproof.

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.

  • Grove compatible interface
  • 2.0-5.5V DC supply
  • response time max about 60mS at fast mode, 220mS at low power mode @VDD=3V
