Overview
Take your robotics projects to the next level with the 4-Channel Infrared Tracking Line Sensor Module. This module consists of four independent TCRT5000 infrared transmitter and receiver pairs mounted on a single sleek board layout, alongside a central control hub.
By emitting infrared light and measuring the reflection, the module instantly detects the contrast between dark lines (which absorb IR light) and light surfaces (which reflect it). It is the ideal sensor array for National Engineering Robotics Contest (NERC) preparations, STEM school projects, and advanced automation layouts.
Key Features
4-Channel Precision: Four sensor probes offer superior path analysis compared to basic single or dual-channel modules, preventing your robot from losing the track at high speeds.
Independent Calibration: Each channel features its own dedicated potentiometer, allowing you to finely tune the detection threshold based on ambient lighting and surface materials.
Clear LED Indicators: Outfitted with individual status LEDs for each channel, providing instant visual feedback during calibration without needing a serial monitor.
Easy Digital Output: Outputs a simple HIGH/LOW digital signal directly to your microcontroller pins, minimizing processing overhead.
Flexible Mounting: Designed with multiple structural mounting holes to easily bolt onto standard smart robot car chassis.
