{"product_id":"grove-infrared-reflective-sensor","title":"Grove - Infrared Reflective Sensor","description":"\u003cp\u003e\n \u003cspan\u003e\n  The reflectivity of infrared light varies with the color and distance of the reflecting surface. According to this principle, Grove - Infrared Reflective Sensor utilizes a RPR220 reflective photosensor module to detect color and distance. When a light-colored object approaches,the signal intensity received by infrared reflective sensor increases and the indicator LED on board turns red. When a dark-colored object approaches, the intensity decreases and the LED turns off.\n \u003c\/span\u003e\n\u003c\/p\u003e\n\u003cp\u003e\n \u003cspan\u003e\n  \u003cbr\u003e\n \u003c\/span\u003e\n\u003c\/p\u003e\n\u003cdiv\u003e\n This sensor is a basic and widely used part in applications such as line-following cars, rotary speed detection, auto data logging on utility meters or other situations where color or distance contrast is sharp.\n \u003cdiv\u003e\n \u003c\/div\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     Operating voltage: 4.5 V - 5.5 V\n    \u003c\/li\u003e\n    \u003cli\u003e\n     Digital output, 0 or VCC\n    \u003c\/li\u003e\n    \u003cli\u003e\n     High resolution sensor;minimum detectable length: 1mm black line\n    \u003c\/li\u003e\n    \u003cli\u003e\n     Effective distanceï¼?4-15mm\n    \u003c\/li\u003e\n    \u003cli\u003e\n     Indicator LED on board\n    \u003c\/li\u003e\n    \u003cli\u003e\n     Sensitivity adjustable via potentiometer\n    \u003c\/li\u003e\n    \u003cli\u003e\n     Small Grove 1X1 compatible interface\n    \u003c\/li\u003e\n   \u003c\/ul\u003e\n   \u003cdiv\u003e\n    \u003chr\u003e\n    \u003ch3\u003e\n     \u003cstrong\u003e\n      \u003cspan class=\"mw-headline\" id=\"Specification\"\u003e\n       Specification\n      \u003c\/span\u003e\n     \u003c\/strong\u003e\n    \u003c\/h3\u003e\n    \u003ctable border=\"1\" cellspacing=\"0\" style=\"width: 85%\"\u003e\n     \u003ctbody\u003e\n      \u003ctr\u003e\n       \u003cth align=\"center\" scope=\"col\"\u003e\n        Item\n       \u003c\/th\u003e\n       \u003cth align=\"center\" scope=\"col\"\u003e\n        Min\n       \u003c\/th\u003e\n       \u003cth align=\"center\" scope=\"col\"\u003e\n        Typical\n       \u003c\/th\u003e\n       \u003cth align=\"center\" scope=\"col\"\u003e\n        Max\n       \u003c\/th\u003e\n      \u003c\/tr\u003e\n      \u003ctr\u003e\n       \u003cth scope=\"row\"\u003e\n        Voltage\n       \u003c\/th\u003e\n       \u003ctd align=\"center\"\u003e\n        4.5V\n       \u003c\/td\u003e\n       \u003ctd align=\"center\"\u003e\n        5V\n       \u003c\/td\u003e\n       \u003ctd align=\"center\"\u003e\n        5.5V\n       \u003c\/td\u003e\n      \u003c\/tr\u003e\n      \u003ctr\u003e\n       \u003cth scope=\"row\"\u003e\n        Current\n       \u003c\/th\u003e\n       \u003ctd align=\"center\"\u003e\n        14.69mA\n       \u003c\/td\u003e\n       \u003ctd align=\"center\"\u003e\n        15.00mA\n       \u003c\/td\u003e\n       \u003ctd align=\"center\"\u003e\n        15.35mA\n       \u003c\/td\u003e\n      \u003c\/tr\u003e\n     \u003c\/tbody\u003e\n    \u003c\/table\u003e\n   \u003c\/div\u003e\n   \u003cdiv\u003e\n   \u003c\/div\u003e\n   \u003chr\u003e\n   \u003ch3\u003e\n    \u003cstrong\u003e\n     Applications\n    \u003c\/strong\u003e\n   \u003c\/h3\u003e\n   \u003cdiv\u003e\n    \u003cul\u003e\n     \u003cli\u003e\n      Line Following\n     \u003c\/li\u003e\n     \u003cli\u003e\n      Rotary Speed Detection\n     \u003c\/li\u003e\n    \u003c\/ul\u003e\n   \u003c\/div\u003e\n   \u003cdiv\u003e\n    \u003chr\u003e\n    \u003ch3\u003e\n     \u003cstrong\u003e\n      Documents\n     \u003c\/strong\u003e\n    \u003c\/h3\u003e\n    \u003cdiv\u003e\n     Please visit our\n     \u003ca href=\"http:\/\/www.seeedstudio.com\/wiki\/Grove_-_Infrared_Reflective_Sensor\"\u003e\n      wiki\n     \u003c\/a\u003e\n     page for more info about this product.
