Ideal for line-following robots and path detection systems, it provides reliable digital outputs for microcontroller-based projects. Its compact design and adjustable sensitivity make it suitable for both beginner and advanced robotics applications.\u003c\/p\u003e\u003ch2\u003eKey Specifications\u003c\/h2\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Voltage\u003c\/td\u003e\n\u003ctd\u003e3.3V–5V DC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCurrent Consumption\u003c\/td\u003e\n\u003ctd\u003e15mA (typical)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDetection Range\u003c\/td\u003e\n\u003ctd\u003e1–8 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput Signal\u003c\/td\u003e\n\u003ctd\u003eDigital (TTL, active low)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eChannels\u003c\/td\u003e\n\u003ctd\u003e3 (left, center, right)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e42 × 12 × 8 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch2\u003eWhat You Can Build With This\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\u003ca href=\"\/products\/kit-line-following-robot\"\u003eLine-following robot with precise path tracking\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/kit-maze-solving-robot\"\u003eMaze-solving robot for competitions\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003eAutomated guided vehicle (AGV) warehouse navigation\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/kit-pi-5-opencv-lane-detection-car\"\u003eSmart car lane detection system\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eCompatibility\u003c\/h2\u003e\u003cp\u003eThe sensor works directly with any 3.3V or 5V microcontroller that accepts digital inputs, including Arduino Uno, Nano, Mega, ESP8266, and ESP32. For 3.3V boards like Raspberry Pi, ensure logic level shifting to protect the GPIO pins. It pairs well with motor drivers and chassis kits for constructing mobile robots.\u003c\/p\u003e\u003ch2\u003eWiring Notes\u003c\/h2\u003e\u003cp\u003eConnect VCC to 5V, GND to ground, and OUT1 (left), OUT2 (center), OUT3 (right) to digital inputs. The outputs go low when a line is detected; adjust onboard trimmer potentiometers to set the threshold for your surface contrast. No external pull-up resistors are needed for most microcontrollers.\u003c\/p\u003e\u003ch2\u003eWhy Buy from Compoden\u003c\/h2\u003e\u003cp\u003eEvery component is sourced from verified suppliers and tested for compatibility before listing.
