A sample chamber is positioned in the optical path between the source and the optical detector to contain a quantity of a sample gas. At least one gas cell enclosing an amount of the gas to be detected is fixedly positioned in the optical path in series with the gas chamber. A mathematical relationship is determined between the detected radiation and the concentration of a sample gas filling the sample chamber.

Abstract: Systems and methods for driving optical sources operating at different wavelengths within a smoke sensor are described herein. Multiple optical sources such as light emitting diodes may be used in a photoelectric smoke sensor to detect particles of different sizes. Photoelectric smoke sensors can operate by pulsing the LEDs and measuring a response in a light sensor. The signal measured at the light sensor changes based on the quantity of particles existing in a smoke chamber. Each optical source may have different operational characteristics and thus require different drive currents to operate. LED driving circuitry according to embodiments discussed herein provide a consistent and reliable drive current to each optical source, while maximizing efficiency of power consumption across a range of possible voltages provided by different power sources.
