Infrared Obstacle Avoidance Sensor Module For Arduino Smart Car Robots 3 Wire Reflective Photoelectric Sensor Detect Obstacles From 2 To 30 cm Works On Three Point Three To Five Volts Sweet For Diy Robotics Projects And Line Tracking

10-Pack Infrared Obstacle Sensor Modules for Arduino ✔️ 2-30 cm detection range, 3.3-5V supply, LM393 output, tiny board

These infrared obstacle avoidance sensor modules are handy tools for DIY robotics, especially Arduino projects. They detect obstacles in front using reflective IR light and provide a clear digital signal to microcontrollers when something is within range. The modules run on 3.3 to 5 V and are easy to wire to VCC, GND, and OUT for quick integration into your robot or line-tracking setup.

✅ Detection range 2-30 cm with approximate 35° field of view; distance adjustable via potentiometer
✅ 3.3-5 V DC supply; red power indicator lights when powered
✅ OUT pin outputs a digital 0/1 signal suitable for microcontrollers or relays
✅ LM393 comparator provides stable switching and low-cost design
✅ Board size 32 mm x 14 mm; 3 mm screw holes for easy mounting
✅ Pack includes 10 sensor modules
