Function: Detects nearby obstacles using infrared (IR) light reflection.

Working Principle: Emits IR light via an IR LED; reflected light from an object is detected by an IR photodiode or phototransistor.

Operating Voltage: 3.3V to 5V DC – compatible with Arduino, ESP32, Raspberry Pi, and similar microcontrollers.

Output Types:

Digital Output (DO): HIGH or LOW signal indicating obstacle presence based on adjustable detection threshold.

Adjustable Sensitivity: Onboard potentiometer to set detection range (typically from a few centimeters up to ~20cm).

Indicator LEDs: Power LED and output status LED for quick visual feedback.

Compact Design: Small and lightweight for easy integration in robotics and automation projects.

Fast Response Time: Real-time obstacle detection with minimal delay.
