8 Channel Grayscale Line Following Sensor Module, Infrared Resistant, No Debugging Required, with STM32/ESP32 16-24mm Height Limit, RGB Optional (Red Light Ver)

Superior Anti-interference Capability & Accurate RecognitionUtilizing visible light (blue/red/green/white) instead of easily interfered infrared light, it fundamentally eliminates infrared interference. Combined with a custom spotlight and light shield, it powerfully suppresses ambient light interference, ensuring stable track recognition under various complex lighting conditions, including white and warm light.; Ready to Use & No Adjustment RequiredExtensive testing has determined the optimal operating height of the module to be 16-24mm. Sensitivity is fixed and optimized within this range, eliminating the need for repeated potentiometer adjustments on-site as with traditional sensors, saving valuable pre-race preparation time and providing a convenient "no adjustment required" experience.

; Flexible Selection & Wide CompatibilityFour light options (WRGB) are available for different colored tracks, easily matched using a quick selection table. An XH 2.54 to DuPont adapter is included, along with complete driver code for five mainstream microcontrollers, including UNO, STM32, and ESP32, for quick and easy setup.; High-Performance Circuitry & Robust StructureThe built-in voltage comparator circuit allows for reading the status of 8 sensors using only 4 I/O ports, significantly saving microcontroller resources. The module is equipped with dual-screw mounting holes and a custom copper tube light shield, ensuring stable installation, effective impact protection, and
