More Information
Summary:A sensor for real-time measurement of the concentration of particles in the atmosphere comprises: * an air inlet for receiving an air stream (40) in which the concentration of particles is to be measured; * at least two stages (20, 30) arranged in cascade and designed to separate the particles according to size, the air inlet being connected to at least one of the two stages; * at least one of the stages (20, 30) comprising means for measuring in real time the concentration of particles; the sensor being characterised in that the means for measuring in real time the concentration of particles comprise at least one surface acoustic wave (SAW) transducer.
