DESCRIPTION

This is a simple touch sensor module. You can use it to replace a traditional push button. Using the TTP223-B touch detector IC 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.

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