An open path gas detection system includes a transmitter and a receiver. The transmitter is configured to generate illumination, having broadband spectrum, across an open path. The receiver is positioned to detect the illumination from the transmitter after the illumination has passed through the open path. The receiver includes at least one spectrometer configured to determine spectroscopic information of the illumination to identify at least one gas of interest based on the spectroscopic information and provide an output based on the at least one gas of interest.

Open path gas detector based on spectrometer

A wireless flame detector includes at least one optical sensor having an electrical characteristic that varies with incident radiation. Measurement circuitry is coupled to the at least one optical sensor and is configured to provide an indication relative to the electrical characteristic of the at least one optical sensor. A controller is coupled to the measurement circuitry to receive the indication and is configured to operate in a low-power mode during which a key flame indicator is monitored, and a second mode that provides full flame detection processing. The controller is configured to enter the second mode upon detection of an event while operating in the first mode. A method of operating a wireless, low-power flame detector is also provided.
