Line Tracker Module (3 Channels)

Overview

This 3-channel Line Tracker Module is an essential sensor for line-following robots. It uses three IR transmitter/receiver pairs to detect the position of a line relative to the sensor, providing digital outputs that indicate whether the line is to the left, center, or right. This makes it ideal for building robots that can follow a line accurately.
