-
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.
