This tool is used to allow remote control of a tractor mounted flame weeder. The arduino measures the temperature at the burner, and when no flame is detected sends an ignition spark to the burner. Both the arduino and the solenoid valve are operated by an on/off switch from a 12 volt power supply. The operator turns the burners on at the beginning of the row, and then off at the end of the row. If the wind blows out the flame, the arduino notices this temperature change, and sends a spark to the burner and reignites the propane.
