Optical obstacle and line sensor based on TCRT5000 with comparator

The optical sensor module based on the TCRT5000 infrared emitter and phototransistor is designed for obstacle detection, measuring the reflectivity of surfaces and line tracking. The board features an LM393 operational amplifier (comparator) and a trimmer resistor that allows precise adjustment of the trigger threshold. The digital (DO) and analog (AO) outputs provide flexible connection options and convenient signal processing when building interactive devices. Features: Product type: optical reflective sensor / line tracking module (Optical Tracking Sensor Module) Specifications: TCRT5000 IR sensor, built-in LM393 comparator, sensitivity adjustment potentiometer, digital (DO) and analog (AO) outputs Purpose: obstacle detection, surface color detection, line tracking in robotics projects
