SISTEMA PER MONITORARE LA QUALITA' DELL'ARIA IN CONDOTTI DI AERAZIONE

It is disclosed a system (1) for monitoring the quality of the air in air ducts, the system comprising an optoelectronic device (2), a network element (4) and an electronic device (5). The optoelectronic device comprises an optical source (2-1) configured to generate an optical beam (F_O) passing through at least a portion of the air inside an air duct (10) and comprises an optoelectronic sensor (2-2) configured to detect the light intensity of at least part of the optical beam which has passed through the portion of the air and to generate, as a function of the detected light intensity, an electrical signal (S_dt) representative of the quantity of particulate present in the portion of the air inside the duct. The optoelectronic device also comprises an electronic circuit (2-3) and a wireless signals transceiver (2-4). The network element (4) is configured to receive a wireless signal (S_r) carrying data representative of the measurement of the quantity of particulate, is configured to process the received data and is configured to transmit a medium-long distance signal (S_Id) carrying the processed data of the measurement of the quantity of particulate present in the portion of the air inside the air duct. The electronic device is configured to receive the medium-long distance signal carrying the processed data of the measurement of the quantity of particulate.
