IR Obstacle Sensor

• The module consists of an IR LED emitter and an IR photodiode/phototransistor receiver.
• It detects obstacles by measuring the reflected infrared light from nearby objects.
• Integrated LM393 comparator provides stable, noise-filtered digital output.
• The onboard potentiometer allows sensitivity adjustment, enabling tuning based on object reflectivity and lighting conditions.
• The module provides Active LOW digital output, meaning the output goes LOW when an obstacle is detected.
• LED indicators allow easy debugging—Power LED (always ON) and Output LED (turns ON on detection).
• Ideal for line-following robots, obstacle-avoiding robots, automation, and proximity sensing.
