Overview
The Yahboom 3 channel infrared tracking sensor module is an analog-output line tracking module designed for smart robot car black-line tracking. It outputs analog values (0–1023) and uses three infrared probes to detect the center line and the left/right edges, helping the controller determine turning angle changes on curves.
Key Features
- 3-channel analog output: 0–1023
- Designed to adapt to complex environments; trigger threshold can be adjusted in code
- 3-probe layout: middle probe detects the line; side probes detect edges (edge detection + line tracking)
- Supports XH2.54 5-pin cable connection and DuPont line connection
- Mounting supported via M3 copper column/screw; can be fixed with rivets or screws and copper columns
- Compared information shown for typical digital tracking modules: digital output 0/1, and may be affected by ambient light and ground material; some require resistance adjustment to read digital signals accurately

Working Principle
Three infrared sensors on the bottom detect the black line using infrared light. The detected distance is converted into an analog quantity and output to the corresponding IO ports. The microcontroller reads the analog quantity of each channel and processes the sensor data to achieve line tracking.

Details
Use three analog IR channels to read the line position continuously, making curve handling smoother than simple on/off sensors.
Analog output provides a wider signal range for tuning and helps maintain stable tracking across different surfaces and lighting.
The 5-pin XH2.54 interface brings out power and three analog signal lines (X1–X3) for easy wiring to your controller.
Compact 40 mm × 29 mm board size with a 10–50 mm detection distance range for typical robot car line-tracking setups.
Mounting with M3 copper columns keeps the sensor height consistent for reliable black-line tracking experiments.
Tutorial resources include example code and documentation to speed up integration with common microcontroller platforms.
Reference files cover wiring and sample routines so you can start reading the three analog channels quickly.
