₹161.00Price

🤖 3 Channel IR Line Detection Module (TCRT5000)

🧩 Overview

  • Multi-sensor line tracking module (3 channels)

  • Uses TCRT5000 IR reflective sensors

  • Designed for line follower robots & path detection

  • Compatible with Arduino, ESP32, Raspberry Pi

⚙️ Working Principle

  • Each sensor emits infrared light (IR LED)

  • Surface reflects IR light back to phototransistor

  • Reflection varies:

    • ⚫ Black surface → low reflection

    • ⚪ White surface → high reflection

  • Comparator converts signal → digital output (HIGH/LOW)

👉 Detects line position using 3 sensors (Left–Center–Right)
