Key Features of IR (Infrared) Obstacle Avoidance Sensor Module
- Reliable LM393 Comparator: Delivers clean, stable digital output with minimal noise, ensuring accurate obstacle detection even in electrically noisy environments.
- Adjustable Detection Range: Onboard precision potentiometer lets you fine-tune sensitivity from approximately 2 cm to 30 cm to suit your specific application.
- Simple 3-Pin Digital Interface: Just VCC, GND, and OUT - connect directly to any microcontroller GPIO pin without additional circuitry or ADC requirements.
- Dual Onboard LEDs: Power indicator confirms the module is energized; signal indicator provides real-time visual feedback when an obstacle is detected, simplifying debugging.
- Wide Voltage Compatibility: Operates seamlessly at both 3.3V and 5V logic levels, making it compatible with Arduino Uno, Nano, Mega, ESP32, ESP8266, Raspberry Pi, and more.
- Compact & Mountable Design: Slim PCB with M3 mounting holes integrates easily into robot chassis, conveyor systems, and custom enclosures.
- Fast Response Time: Near-instantaneous detection allows real-time obstacle avoidance in moving robots and automated systems.
- Low Power Consumption: Draws only ~20 mA, ideal for battery-powered and portable projects.
How It Works
The module pairs an infrared LED transmitter with a photodiode receiver positioned side by side. The IR LED continuously emits a beam of ~940 nm infrared light. When an object enters the detection zone, the IR light reflects off the surface and is picked up by the photodiode. The LM393 comparator compares the received signal level against a threshold set by the onboard potentiometer. If the reflected signal exceeds the threshold (obstacle present), the OUT pin goes LOW; if no obstacle is detected, OUT remains HIGH. This clean digital output can be read directly by any microcontroller.
