TCRT5000 IR Line Tracking Sensor Module

The TCRT5000 IR Line Tracking Sensor Module is a reflective infrared sensor designed to detect the presence and reflectivity of a surface in front of it, making it ideal for line-following robots and object-detection projects. It pairs an infrared emitter/phototransistor pair with an onboard LM393 comparator to output a clean, stable detection signal.

Key features:

• Reflective IR Sensing: Uses a TCRT5000 infrared emitter-receiver pair to detect black and white surfaces based on reflected light.
• Onboard Comparator: Built-in LM393 comparator converts the analog signal into a stable digital output.
• Adjustable Sensitivity: Onboard potentiometer allows fine-tuning of the detection threshold.
• Status Indicators: Power and signal LEDs give a quick visual read of the sensor state.
• Short-Range Detection: Effective sensing distance of roughly 1mm to 25mm from the target surface.
• Easy Integration: Simple 3 to 4-pin interface compatible with Arduino and other microcontrollers.
