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 For all Grove users (especially beginners), we provide you guidance PDF documents.

For technical support, please post your questions to our . Introduction It’s time to replace a traditional push button with the touch sensor module. It uses the TTP223-B touch detector IC to measure the capacitance of a metallic pad. It can detect the change in capacitance when a finger is near by. The TTP223 has Fast/Low Power modes for your selection, and the TTP223-B is set as Low Power mode by default. When detecting a key touch, it will switch to Fast mode. After the key touch is released, there will be about 12 seconds until it returns to Low Power mode which can help saving the power. You can even 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.
