TCRT5000 Line Tracking Sensor Module – 4P Infrared Reflective Sensor

The TCRT5000 Infrared Sensor Module is a compact and efficient line tracking and object detection sensor used widely in robotics, automation, and embedded systems. It is ideal for use in line follower robots, sumo robots, and mini robotic projects. The module integrates a high-speed and high-sensitivity TCRT5000 IR sensor and features a digital output with adjustable sensitivity via an onboard potentiometer.

🔧 Key Features

• 📏 Detection Range: ~0–30 cm on bright white surface, ~0–10 cm on matte black surface
• 🎚️ Adjustable Sensitivity: Onboard potentiometer
• ⚡ Operating Voltage: 5V DC
• 🔌 Output Type: Digital (High = object detected)
• 💡 Onboard Indicator LED: Lights up when object is detected
• 📦 Connector: 4-pin interface (VCC, GND, DO, AO optional)
• 📐 Module Dimensions: 30mm × 16mm
• 🔗 Included: Female-to-Female jumper wires for easy prototyping

🛠️ Applications

• 🤖 Line-following robots
• 🚗 Obstacle and edge detection systems
• 🔄 Rotary encoders and position feedback
• 📦 Object counting systems
• 🎮 DIY Arduino and microcontroller projects

📌 How It Works

• ✅ When an object is detected, the digital output pin provides 5V HIGH.
• ❌ When no object is detected, the output remains at 0V LOW.

Thanks to its low cost, small form factor, and ease of use, the TCRT5000 module is a go-to choice for educational and professional robotics projects alike.
