{"product_id":"grove-touch-sensor","title":"Grove - Touch Sensor","description":"\u003cp\u003e\n 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.\n\u003c\/p\u003e\n\u003chr\u003e\n\u003ch3\u003e\n \u003cstrong\u003e\n  Features\n \u003c\/strong\u003e\n\u003c\/h3\u003e\n\u003cdiv\u003e\n \u003cul\u003e\n  \u003cli\u003e\n   Grove compatible interface\n  \u003c\/li\u003e\n  \u003cli\u003e\n   2.0-5.5V DC supply\n  \u003c\/li\u003e\n  \u003cli\u003e\n   response time max about 60mS at fast mode, 220mS at low power mode @VDD=3V\n  \u003c\/li\u003e\n  \u003cli\u003e\n   Low power consumption\n  \u003c\/li\u003e\n  \u003cli\u003e\n   2.0cm x 2.0cm twig module\n  \u003c\/li\u003e\n  \u003cli\u003e\n   Power indicator led\n  \u003c\/li\u003e\n \u003c\/ul\u003e\n\u003c\/div\u003e\n\u003chr\u003e\n\u003ch3\u003e\n \u003cstrong\u003e\n  Applications Ideas\n \u003c\/strong\u003e\n\u003c\/h3\u003e\n\u003cdiv\u003e\n \u003cul\u003e\n  \u003cli\u003e\n   Inconspicuous button\n  \u003c\/li\u003e\n  \u003cli\u003e\n   Water proofed electric product\n  \u003c\/li\u003e\n  \u003cli\u003e\n   Button key replacement\n  \u003c\/li\u003e\n \u003c\/ul\u003e\n \u003cdiv\u003e\n  \u003chr\u003e\n  \u003ch3\u003e\n   \u003cstrong\u003e\n    Documents\n   \u003c\/strong\u003e\n  \u003c\/h3\u003e\n  \u003cp\u003e\n   Please visit our\n   \u003ca href=\"http:\/\/www.seeedstudio.com\/wiki\/index.php?title=Twig_-_Touch_Sensor\"\u003e\n   \u003c\/a\u003e\n   \u003ca href=\"http:\/\/www.seeedstudio.com\/wiki\/index.php?title=Twig_-_Touch_Sensor\"\u003e\n    wiki\n   \u003c\/a\u003e\n   page for more info about this product.
