What is it?
OCIEngine is an infrared spectrometer that measures Volatile Organic Compounds (VOC) in the air. It is specific to analyse a molecule of interest, such as acetone.
The measuring chamber of the sensor is crossed by infrared radiation. When the air is introduced into this chamber, the molecules of interest absorb a part of the radiation, which reduces the intensity of the optical signal. The concentration of the gas can therefore be deduced according to the Beer-Lambert’s physical law.
