Hiwonder 4-Channel IR Line Follower Sensor Module Tracking & Obstacle Avoidance, 4-Way Detection for Maker DIY Robot Cars

The Hiwonder 4-Channel IR Line Follower Sensor Module is a high-precision tracking and obstacle avoidance solution designed for custom robot builds. Ideal for students, educators, and makers, this module enables precise navigation across complex tracks. It integrates seamlessly with various chassis types, making it a versatile choice for your next South African robotics project.

High-precision grayscale detection

Equipped with miniature, high-precision IR probes, this module delivers accurate grayscale detection across a 1mm to 10cm range. This ensures reliable surface tracking under varying conditions.

Advanced line following navigation

Your robot can achieve high-difficulty navigation, easily negotiating right-angle turns, crossroads, acute-angle U-turns, and T-junctions. The four-channel array provides the resolution needed for complex track layouts.

Versatile chassis integration

The module ensures simple and efficient line-following deployment across various robot car chassis. It is fully compatible with 2WD, 4WD differential drive, Mecanum wheels, omnidirectional wheels, and Ackermann steering setups.

Independent sensitivity adjustment

Four onboard knobs provide 150-degree independent sensitivity adjustment. This allows you to fine-tune each channel individually to match your specific track surface and ambient lighting.

Flexible connection methods

The sensor is designed to interface easily with your controller, offering both GPIO and I2C versions. This flexibility simplifies wiring and integration into your custom control systems.

Simple chassis installation

Secure the sensor to your chassis using M3 standoffs and screws, maintaining a 0.8cm clearance between the probe and the ground. You can adjust the standoff length to match your specific chassis height for optimal sensing performance.
