It outputs a digital signal when it detects a reflective surface or obstacle within a short range, making it ideal for line-following robots and proximity detection applications. The onboard comparator provides clean digital output, and sensitivity adjustment allows fine-tuning for different surfaces.\u003c\/p\u003e\n\n\u003ch2\u003eKey Specifications\u003c\/h2\u003e\n\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\u003eSensor\u003c\/td\u003e\n\u003ctd\u003eTCRT5000 (IR LED + Phototransistor)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eOperating Voltage\u003c\/td\u003e\n\u003ctd\u003e3.3V to 5V DC\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eDetection Range\u003c\/td\u003e\n\u003ctd\u003e0.2 to 1.5 cm (adjustable)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eOutput Type\u003c\/td\u003e\n\u003ctd\u003eDigital (0 or 1), active low\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eIndicator LEDs\u003c\/td\u003e\n\u003ctd\u003ePower (red) and Output (green)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e3.2 cm x 1.4 cm x 0.7 cm\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eWhat You Can Build With This\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\u003ca href=\"\/products\/kit-line-following-robot\"\u003eLine-following robot for Arduino and ESP32 projects\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003eTabletop edge detection and cliff avoidance for small robots\u003c\/li\u003e\n  \u003cli\u003eObject counting on conveyor belts using reflective tape\u003c\/li\u003e\n  \u003cli\u003eDIY rotary encoder using a slotted wheel and reflective pattern\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eThis module outputs 3.3V-5V logic levels and works directly with Arduino Uno, Nano, Mega, ESP8266, and ESP32 development boards. For 3.3V boards like Raspberry Pi, use a voltage divider or level shifter on the OUT pin to protect GPIOs. It is commonly paired with motor drivers (L298N, L293D) and microcontroller boards in robotics kits.\u003c\/p\u003e\n\n\u003ch2\u003eWiring Notes\u003c\/h2\u003e\n\u003cp\u003eConnect VCC to 5V (or 3.3V), GND to GND, and OUT to any digital I\/O pin. The sensitivity potentiometer adjusts the threshold: turn clockwise to increase detection distance. No external pull-up resistor is needed; the comparator output is push-pull. For best line detection, mount the sensor 0.5-1 cm above the surface.\u003c\/p\u003e\n\n\u003ch2\u003eWhy Buy from Compoden\u003c\/h2\u003e\n\u003cp\u003eEvery component is sourced from verified suppliers and tested for compatibility before listing.
