Infrared Obstacle Avoidance Sensor Module For Arduino, 3-Wire Reflective Photoelectric Sensor, 2 To 30 Cm Detection Range, 35 Degree Field Of View, Green LED Indicator, Dope Tech For Smart Car Robots, Pack Of 10

Infrared Obstacle Sensor Module for Arduino - 2-30 cm Range
✔️ 2-30 cm range, 35° FOV, 10-Pack, green LED indicator on detect

The infrared obstacle sensor module is a compact 3-wire device used in Arduino projects to detect obstacles through IR reflection. It helps with obstacle avoidance, line tracking, and automatic navigation in small robots and smart cars.

✅ 2-30 cm adjustable distance via potentiometer
✅ 3-wire interface: VCC, GND, OUT compatible with 3.3-5V MCUs
✅ Green LED lights when obstacle detected; OUT outputs a low signal
✅ Operating voltage range 3.3V-5V; can drive a 5V relay

💡 What is an infrared obstacle sensor module used for in Arduino robotics and obstacle avoidance systems?

It’s handy for giving your project a sense of distance and collision awareness. - Detects reflective obstacles in the 2-30 cm range
- Outputs a digital low on detection that can drive a microcontroller IO or a relay
- Range adjustable with potentiometer for tuning
- Works on 3.3-5V with a visible green LED indicator
