{"product_id":"grove-water-sensor","title":"Grove - Water Sensor","description":"\u003cp\u003e\n \u003cspan\u003e\n  This water sensor module is part of the Grove (Twig) system. This sensor works by having a series of exposed traces connected to ground and interlaced between the grounded traces are the sens traces. The sensor traces have a weak pull-up resistor of 1 MΩ. The resistor will pull the sensor trace value high until a drop of water shorts the sensor trace to the grounded trace. Believe it or not this circuit will work with the digital I\/O pins of your Arduino or you can use it with the analog pins to detect the amount of water induced contact between the grounded and sensor traces.\n \u003c\/span\u003e\n\u003c\/p\u003e\n\u003cdiv\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    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    High sensitivity\n   \u003c\/li\u003e\n  \u003c\/ul\u003e\n  \u003cdiv\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      Rainfall detecting\n     \u003c\/li\u003e\n     \u003cli\u003e\n      Liquid leakage\n     \u003c\/li\u003e\n     \u003cli\u003e\n      Tank overflow detector\n     \u003c\/li\u003e\n    \u003c\/ul\u003e\n    \u003cdiv\u003e\n     \u003cdiv\u003e\n      \u003chr\u003e\n      \u003ch3\u003e\n       \u003cspan\u003e\n        Documents\n       \u003c\/span\u003e\n      \u003c\/h3\u003e\n      \u003cp\u003e\n       Please visit our\n       \u003ca href=\"http:\/\/garden.seeedstudio.com\/index.php?title=Seeeduino_v2.21\"\u003e\n       \u003c\/a\u003e\n       \u003ca href=\"http:\/\/garden.seeedstudio.com\/index.php?title=Twig_-_Water_Sensor\"\u003e\n        wiki page\n       \u003c\/a\u003e\n       for more info about this product.
