4 Channel Infrared Tracking Sensor Module 4C-ITSM

Product Overview

The module featured in your document is a 4-Channel IR Line Follower Sensor Module. It operates on the principle of light reflection to detect whether a contrasting line is present on the floor surface beneath it. The board features four independent infrared transceiver modules that actively emit and receive light, sending data back to a central control card. It is highly popular in DIY robotics for automated line-following applications, maze navigation, and basic track tracking.
