4 Channel Infrared Tracing Module
Description:
4-Channel Infrared Tracing Module is a sensor board that uses infrared (IR) reflection to detect the presence or absence of a line beneath the sensor. It is most commonly used in line-following robots and path-tracking systems.module includes four IR transmitter-receiver pairs (one for each channel), which can detect the contrast between a dark line (e.g., black tape) and a lighter background (e.g., white floor).
Features:
1. 4 independent IR sensors for accurate line detection
2. Digital output for easy interfacing with microcontrollers
3. Onboard signal indicator LEDs for real-time status feedback
4. Plug-and-play design for Arduino, ESP32, or Raspberry Pi projects
5. Ideal for robot line tracking, edge detection, or position feedback
6. Lightweight, durable PCB design
