{"product_id":"grove-infrared-reflective-sensor-v12","title":"Grove - Infrared Reflective Sensor v1.2","description":"\u003cp\u003eGrove - Infrared Reflective Sensor v1.2 can be used for detection of proximity and color of objects. The reflective photosensor - \u003cstrong\u003eRPR\u003c\/strong\u003e-\u003cstrong\u003e220\u003c\/strong\u003e used in this module consists of an infrared light emitting diode and a high –sensitivity phototransistor. Light-colored objects directly in front of the sensor will reflect more infrared light as well as generate more current in the phototransistor than an object with dark-colored surfaces, this can be tell from a built-in indicator LED which will turn red with sufficient flow of current. Also, the intensity of the reflective light increases as the object getting closer. You can adjust the potential-meter on the back of the board if you want to detect a specific object (eg. Black line) at a certain distance.\u003c\/p\u003e\n\u003cp\u003eThis sensor is a widely used in applications such as line-following robots, rotary speed detection, auto-data logging on utility meters or other situations where color or distance contrast is sharp.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eEasy to use\u003c\/li\u003e\n\u003cli\u003ePanel-mounting Grove interface\u003c\/li\u003e\n\u003cli\u003eDigital output: 0 or VCC\u003c\/li\u003e\n\u003cli\u003eBuilt-in indicator LED\u003c\/li\u003e\n\u003cli\u003eThreshold adjustable via potentiometer\u003c\/li\u003e\n\u003cli\u003ePower supply: 3.5 – 5.5V DC\u003c\/li\u003e\n\u003cli\u003eReflective Photosensor: RPR-220\u003c\/li\u003e\n\u003cli\u003eEffective working distance: 4-15mm\u003c\/li\u003e\n\u003cli\u003eMinimum detectable width for monochrome lines: 10mm\u003c\/li\u003e\n\u003cli\u003eConnector: 4 pin Buckled Grove interface\u003c\/li\u003e\n\u003cli\u003eDimension: 20mm x 20mm\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eProduct number: Seeed 101020174\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\u003cstrong\u003eResources\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eWiki Page\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Seeed","offers":[{"title":"Default Title","offer_id":46375179649081,"sku":"upr1787258005966","price":3.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0795\/9176\/8121\/files\/grove---infrared-reflective-sensor-v12_1.jpg?v=1787258014","url":"https:\/\/myoutfitstore.shop\/products\/grove-infrared-reflective-sensor-v12","provider":"My Store","version":"1.0","type":"link"}
