This Arduino-based system enhances the safety and efficiency of tractor-mounted flame weeders by automatically detecting flame outages and reigniting the burners. It uses a thermocouple to monitor burner temperature and triggers a spark ignition if the flame is extinguished, such as by wind. The system operates on a 12V power supply and is controlled via a manual on/off switch. Detailed build instructions and supporting materials are provided for replication and adaptation.
