摘要： A particle detector. The particle detector comprises one or more light sources, an optical sensor, and a controller. The one or more light sources are collectively operable to simultaneously produce at least two wavelength ranges of emitted light. The optical sensor is configured to sense light of the at least two wavelength ranges emitted by the one or more light sources and to distinguish each range. The controller is configured to detect particles based on the light sensed by the optical sensor.
