IR Infrared Obstacle Avoidance Sensor Module for Arduino

IR Infrared Obstacle Avoidance Sensor Module

Build smarter robots and automation projects with this infrared obstacle avoidance sensor module. It uses an infrared transmitter and receiver to detect nearby objects and provides a simple digital signal for Arduino and other microcontroller projects.

Key features

• Infrared-based obstacle and object detection
• Adjustable detection sensitivity using the onboard potentiometer
• Simple digital output for easy microcontroller interfacing
• Suitable for robot cars, line-following projects, automatic doors, and DIY automation
• Compact module for breadboard and chassis-mounted electronics projects

Typical specifications

• Operating voltage: commonly 3.3V to 5V, depending on the module version
• Detection distance: typically adjustable and approximately 2 cm to 30 cm
• Interface: VCC, GND, and digital OUT on common versions

Compatibility note

Detection distance can vary with object color, surface finish, ambient light, and the exact module version. Check the module pin labels and logic level before connecting it to 3.3V boards such as ESP8266, ESP32, or Raspberry Pi.

Package includes

• 1 x IR infrared obstacle avoidance sensor module
