A simple and reliable infrared sensor for detecting nearby objects without contact. Perfect for robots, automation, and beginner electronics projects.

The module detects obstacles using reflected IR light and outputs a clean digital signal that’s easy to read with any microcontroller.

Key Features

• Normally HIGH output (LOW when obstacle detected)
• Adjustable sensitivity (potentiometer)
• Fast and stable digital signal
• Easy 3-pin connection (VCC, GND, OUT)
• Built-in indicator LED

Typical Uses

• Obstacle-avoiding robots
• Line tracking
• Proximity detection
• DIY projects
