IR Obstacle Detection Sensor Module:

The IR Obstacle Detection Sensor Module is a compact yet powerful sensor designed for detecting objects or obstacles using infrared light technology. This sensor is a must-have in modern robotics, automation, and IoT-based smart systems. Ideal for both beginners and professionals working on STEM electronics, this module is commonly used in Arduino-based robots, line-following cars, and smart security systems.

🧪 Technical Specifications IR Obstacle Detection:

• Operating Voltage: 3.3V – 5V DC

• Current Consumption: ~20mA

• Detection Range: Adjustable, approx. 2cm – 30cm

• Output Type: Digital (High/Low signal)

• Interface Type: 3-pin (VCC, GND, OUT)

• Comparator IC: LM393

• IR Components: Infrared Emitter and Receiver

• Adjustable Sensitivity: Via onboard potentiometer

• PCB Size: Compact (approx. 3.1cm x 1.4cm)

This sensor works by emitting infrared rays from an IR LED. When an object comes within range, the reflected IR light is picked up by the photodiode. The onboard LM393 comparator processes this signal and produces a clear digital HIGH or LOW output, making it easily interpretable by any microcontroller such as Arduino UNO, ESP32, Raspberry Pi, STM32, and more.

🔧 Applications:

• Obstacle & Proximity Detection

• Automated Navigation Systems

• Line-Following Robots

• Security Alarm Systems

• DIY Arduino Projects

• Home Automation Modules

• Smart Parking Systems

Whether you are creating a robotic vehicle that avoids collisions or building a home automation system that senses motion or presence, this IR module delivers performance and precision at a minimal cost.
