TCRT5000 IR Tracking Sensor Module

Description

Build precise line-following robots and obstacle detection systems with the highly sensitive TCRT5000 IR Tracking Sensor Module. This premium electronic module combines an infrared emitting diode and an infrared phototransistor into a single compact housing, working effectively to measure surface reflectivity. It is widely used in smart cars, manufacturing conveyor belt counters, and auto-sorting systems because it perfectly distinguishes between black lines and white backgrounds. Operating on a flexible 3.3V to 5V circuit, it provides both a clean analog output (for tracking gradient grayscale shifts) and a digital output with an adjustable onboard potentiometer threshold for immediate binary signaling. You can easily connect this module to your favorite microcontroller platform.
