LED-BASED ARCHITECTURE FOR AIR EMISSION MONITORING

• Abstract:

  We present an architecture of controlling a proposed spectrometer system for detecting pollution in water and gas. The system is based on LED sensors using a Michelson interferometer and stepper–motor for moving split mirrors. The system is designed so that changes in LED light intensity could allow to detect a wide spectrum of polluted substances. The architecture uses a special duty-cycle to reduce the uncertainty of pollution detection. The electronic board of the system has been constructed and tested with encouraging results thanks to the use of a PMT (photomultiplier tube).
