This compact board is compatible with both 3.3V and 5V systems.\u003cbr\u003e\nThe QRE1113 infrared reflectance sensor board consists of two components: an LED that emits infrared light, and a phototransistor sensitive to infrared light.\u003cbr\u003e\nWhen power is supplied to the VCC and GND pins, the internal infrared LED of the sensor turns on. A 100Ω resistor is mounted on the board in series with the LED to limit the current.\u003cbr\u003e\nThe output of the phototransistor is connected to a 10nF capacitor.\u003cbr\u003e\nThe faster the capacitor discharges, the higher the reflectivity of the detected surface.\u003cbr\u003e\nThis type of sensor is widely used in production line tracking robots.\u003cbr\u003e\nWhite surfaces reflect more light than black surfaces, so the capacitor discharges faster when the sensor is aimed at a white surface than at a black one.\u003cbr\u003e\nPower input and output pins are broken out to a 3-pin header with 0.1-inch spacing.\u003cbr\u003e\nMounting holes are also provided on the board for easy installation on other boards.\u003cbr\u003e\nProduct Parameters\u003cbr\u003e\nOperating Voltage: 5V DC\u003cbr\u003e\nOperating Current: 25mA\u003cbr\u003e\nInterface: Digital I\/O compatible, no ADC required\u003cbr\u003e\nOptimal Sensing Distance: 0.125 inches (approx. 3mm)\u003cbr\u003e\nDimensions: 0.3 × 0.55 inches\n\u003cp style=\"text-align:left;margin:0;\"\u003e\u003cimg src=\"https:\/\/ae01.alicdn.com\/kf\/S9a040450ff7047b1b62e6c5cd3b3a79bh.jpg?width=800\u0026amp;height=800\u0026amp;hash=1600\"\u003e\u003cimg src=\"https:\/\/ae01.alicdn.com\/kf\/S0c48b1b8d6b9411985dd9b2042d126c6L.jpg?width=800\u0026amp;height=800\u0026amp;hash=1600\"\u003e\u003cimg src=\"https:\/\/ae01.alicdn.com\/kf\/S7b4a5c52b7bd421b908f73b79eb964fcJ.jpg?width=960\u0026amp;height=960\u0026amp;hash=1920\"\u003e\u003cimg src=\"https:\/\/ae01.alicdn.com\/kf\/S3422ade86e0f4e9e850573a2597eaf52L.jpg?width=960\u0026amp;height=960\u0026amp;hash=1920\"\u003e\u003cimg src=\"https:\/\/ae01.alicdn.com\/kf\/S2494c40132654eed88fdad92245c2bd4o.jpg?width=800\u0026amp;height=800\u0026amp;hash=1600\"\u003e\u003cimg src=\"https:\/\/ae01.alicdn.com\/kf\/S0c48b1b8d6b9411985dd9b2042d126c6L.jpg?width=800\u0026amp;height=800\u0026amp;hash=1600\"\u003e\u003cimg src=\"https:\/\/ae01.alicdn.com\/kf\/S9a040450ff7047b1b62e6c5cd3b3a79bh.jpg?width=800\u0026amp;height=800\u0026amp;hash=1600\"\u003e\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/div\u003e\r\n","brand":"Yoeruyo","offers":[{"title":"WHITE","offer_id":55420150841643,"sku":"14:29","price":119.7,"currency_code":"USD","in_stock":true},{"title":"Red","offer_id":55420150874411,"sku":"14:10","price":119.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1000\/5744\/8747\/files\/Sea799095bfc24ec69db922718df5aec1f.webp?v=1788499649","url":"https:\/\/yoeruyo.com\/products\/10pcs-qre1113-ir-reflective-sensor-module-3-3v-5v-line-sensor-breakout-for-arduino-diy-robot","provider":"Yoeruyo","version":"1.0","type":"link"}
