1‑Channel Infrared Obstacle Avoidance & Line Tracking Module

The BIT‑TREE 1‑channel infrared obstacle avoidance line tracking module works on the infrared reflection detection principle. It supports 3.3V–5V wide‑voltage power supply and outputs digital switching signals. A high‑precision on‑board potentiometer lets users adjust detection sensitivity for reliable ranging results. Pre‑drilled mounting holes simplify wiring installation. The sensor fits line‑following vehicles, obstacle‑avoidance robot builds, boundary detection tasks and maker education projects.
