WIRELESS COMBUSTION/EFFICIENCY ANALYZER

A technician uses a wireless apparatus and system to vary air or fuel in the burner to optimize efficiency and safety. A wireless remote sensor unit has a probe in a flue to draw a sample of combustion gas from the flue for gas sensors and a temperature sensor. The sensors generate analog signals of gas identity, concentration and temperature that are converted to digital signals by an A-to-D converter. A wireless transceiver sends digital signals to a hand held unit or central computer via wireless transmission. The hand held unit receives the digital signals and displays an analysis of the signals. The analysis may be performed by any one of the remote sensor unit, the hand held unit, or the central computer. The wireless unit also receives control signals for the hand held unit or the central computer.
