Air quality monitoring system for Smart Cities

​

AQM-03 is designed to measure the concentration of toxic gases SO2, NO2, O3, CO, total volatile organic compounds and the mass concentration of particulate matter in the ambient air.

The devices are equipped with a robust, weatherproof, metal housing. Inside the case, the device consists of measurement units, a power supply and a data processing unit, which includes a software system for remote technical support, data management and analytics. The AQM-03 also contains a battery pack, which allows the device to be kept in working order for 6 hours in the event of a power failure.
