JSUMO Dual Micro Line Sensor ML2

The Dual Micro Line Sensor ML2 is a precision edge detection module specifically engineered for competitive robotics, particularly sumo robot platforms . It is designed to enhance detection reliability of the white boundary line (dohyo edge) while minimizing false detections caused by surface reflections or uneven lighting. The ML2 integrates a dual infrared sensor system . Unlike single-sensor modules, it only produces an output when both IR sensors simultaneously detect the white line , ensuring a higher level of accuracy and stability during robot movement. This logical filtering significantly improves performance in fast-paced competition environments. Its ultra-compact and lightweight design makes it especially suitable for micro and mini sumo robots , where size and weight constraints are critical. Despite its small form factor, the sensor delivers reliable and consistent performance. The module outputs a digital signal (logic HIGH or LOW) , making it easy to interface directly with microcontrollers such as Arduino, PIC, STM32, and ARM-based systems. It supports both 3.3V and 5V operation , providing flexibility across different hardware platforms. With its clean design, clearly labeled pins, and robust detection logic, the ML2 is widely recommended for competitive sumo robotics where accuracy and reliability are essential.
