IR SENSOR

Infrared (IR) Obstacle Avoidance and Proximity Sensor Module

The Infrared (IR) Obstacle Avoidance Sensor is a versatile and easy-to-use module designed for non-contact object detection. It works by emitting a beam of infrared light from an IR LED and then detecting whether the beam is reflected off an object using an IR photodiode. An onboard comparator circuit processes the signal, providing a simple digital HIGH or LOW output, making it incredibly easy to integrate with any microcontroller like an Arduino, ESP32, or Raspberry Pi.

🔧 Key Features

• Non-Contact Detection: Senses objects in its path without any physical contact, preventing wear and tear.
• Adjustable Sensitivity: Features an onboard potentiometer that allows you to precisely fine-tune the detection range, typically from 2cm to 30cm.
• Simple Digital Output: Provides a straightforward HIGH/LOW logic output, making it simple to read with a digital input pin on a microcontroller.
• Wide Compatibility: Operates on a common 3.3V to 5V supply, making it compatible with most hobbyist electronics platforms.
• Status Indicator LEDs: Includes onboard LEDs for power indication and to show when an object is detected, which is great for quick debugging.
• Stable Performance: Uses a reliable LM393 voltage comparator for a clean, stable, and interference-free output signal.

💡 Applications

• Robotics: The core component for creating obstacle-avoiding robots and rovers.
• Line Followers: Can effectively detect a black line on a white surface (or vice versa) due to differences in IR reflection.
• Automation: Use it as a proximity switch to trigger events, such as in automatic hand sanitiser dispensers or faucets.
• Object Counting: Ideal for counting items as they pass by on a conveyor belt or through an opening.
• Security Systems: Can be used as a simple tripwire sensor for basic alarm systems.
