5 Channel Tracking Sensor Module
The 5-Channel Line Tracking Sensor Module is a high-sensitivity infrared sensor array designed specifically for precision line-following and edge-detection applications in autonomous mobile robotics. Built around five aligned TCRT5000 (or equivalent) infrared transmitter and phototransistor sensor pairs, the module emits IR light and measures reflected intensity to differentiate between high-contrast surfaces, such as black lines on a white background. It incorporates onboard comparator ICs (such as the LM393) to output clear TTL digital signals (HIGH/LOW) for each channel, supported by individual LED indicator lights that provide real-time visual feedback for active sensors. Operating reliably on a 3.3V to 5V DC power supply, the board features an onboard potentiometer to adjust detection sensitivity across varying line widths and ground clearances. With its standard breadboard-friendly header pins and pre-drilled mounting holes, this compact tracking bar integrates seamlessly with Arduino, ESP32, STM32, and Raspberry Pi platforms to provide fast, multichannel spatial feedback for warehouse AGVs, educational robot cars, and line-following competition platforms.
