The TCRT5000 5-Channel Array Tracking Sensor Module is a reflectance-based infrared sensor array designed for accurate line tracking and surface detection. It consists of five TCRT5000 IR emitter–receiver pairs arranged in a linear array, allowing precise detection of black/white contrast and edge positioning. This module is widely used in line follower robots, AGV systems, and autonomous navigation projects where reliable path detection is required.
