IR Infrared Obstacle Avoidance Sensor Module for Arduino DIY Robot

Explore the World of Advanced Obstacle Detection

Upgrade your DIY robot with our IR Infrared Obstacle Avoidance Sensor Module designed for seamless integration with Arduino projects. This sensor module boasts exceptional adaptability to various environments, featuring a pair of infrared transmitting and receiving tubes. When the emitted infrared frequency encounters an obstacle’s reflecting surface, the receiving tube captures the reflected signal. Through meticulous comparator circuitry, the distinct green indicator illuminates, accompanied by a low-level digital signal output through the interface. This versatile module offers an adjustable detection distance, ranging from 2 to 30cm, easily modified using the precision potentiometer knob.

Key Features:

  • Wide adaptability to diverse environments
  • Infrared emitting and receiving tubes for accurate detection
  • Configurable detection distance (2 ~ 30cm) via precision potentiometer
  • 35° detection angle for comprehensive coverage
  • Seamless integration with 3.3V to 5V systems
  • LM393 comparator ensures reliable performance
  • Ideal for robot obstacle avoidance, line tracking, and more


  1. Adjustable Detection: Modify detection distance through the potentiometer
  2. Reflectivity Sensitivity: Targets’ reflectivity and shape influence detection range
  3. Easy Connectivity: OUT port directly connects to microcontroller IO port or drives a 5V relay
  4. Stable Performance: Employing LM393 comparator for consistent results
  5. Effortless Powering: Compatible with 3V to 5V DC power supply
  6. Simple Installation: 3mm screw holes facilitate secure and hassle-free fixing
  7. Compact Design: Circuit board dimensions: 3.2cm x 1.4cm
  8. Pre-Calibrated Threshold: Shipped with pre-adjusted compare threshold voltage, avoiding unnecessary adjustments


  1. VCC Voltage Range: 3.3V to 5V, suitable for 5V single-chip microcontrollers and 3.3V systems
  2. GND Connectivity: External GND connection for stability
  3. Digital Output: OUT interface provides binary output (0 and 1) on a small plate

Elevate your DIY robot’s capabilities with the IR Infrared Obstacle Avoidance Sensor Module. Embrace innovation and precision in obstacle detection and enhance your robot’s performance today.
