IR Sensor

The IR Proximity Sensor is designed to detect the presence of objects based on infrared light reflection. It is widely used in line-following robots to track and follow lines on the ground. This sensor is ideal for projects where object detection, obstacle avoidance, or line tracking is required. With its adjustable sensitivity and easy-to-use interface, it's a must-have for robotics and automation enthusiasts.

Key Features

• Operating Voltage: 3.3V – 5V
• Detection Range: 2 cm – 15 cm (varies with surface and ambient light)
• Output Type: Digital (High/Low)
• Adjustable Sensitivity: Potentiometer for tuning detection range
• Response Time: Fast detection with minimal delay
• Sensing Technology: Infrared (IR) LED and Photodiode
• Interface: 3-pin (VCC, GND, OUT)
• Mounting: Easy to attach to robot chassis for line tracking

Technical Details

How It Works

1. IR Emission: The sensor emits infrared light via the IR LED.
2. Reflection: When the sensor is above a line (usually black on white), the light reflects back from the surface.
3. Detection: The reflected light is captured by the photodiode, triggering a HIGH signal on the output pin.
4. Line Tracking: If the output is HIGH, the sensor is over the line, and if LOW, it's off the line. This can be used to adjust the movement of a robot.
