Grove - Twig - Touch Sensor

3.65 €3.65

Availability: Retired

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. 
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 
  • 2.0cm x 2.0cm twig module 
  • Power indicator led 
Applications Ideas 
  • Inconspicuous button 
  • Water proofed electric product 
  • Button key replacement
