3 Channel IR Infrared CTRT5000 Line Detection Module

β‚Ή161.00Price
πŸ€– 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
βš™οΈ Working Principle
  • Each sensor emits infrared light (IR LED)
  • Surface reflects IR light back to phototransistor
  • Reflection varies:
    • ⚫ Black surface β†’ low reflection
    • βšͺ White surface β†’ high reflection
  • Comparator converts signal β†’ digital output (HIGH/LOW)
πŸ‘‰ Detects line position using 3 sensors (Left–Center–Right)
