ABSTRACT:
The disclosure relates to an air pollution sensor system incorporated in an enclosure, the enclosure including an air handling system inside an air duct, the air duct enabling a communication between air inside the enclosure and air outside the enclosure. The air duct including an air inlet for receiving air and an air outlet for releasing handled air inside the enclosure. The air pollution sensor system includes at least one ultra fine particle sensor capable of sensing particles with a diameter in a range of approximately 5-2500 nm, preferably in a range of approximately 5-1000 nm and more preferably in a range of approximately 5-500 nm inside the enclosure and providing a pollution information signal in response to the sensing of the particles. The disclosure further relates to various types of ultra fine particle sensors and air handling systems.
