BETTAIR STATIC NODE MK2 SERIESFOR MAPPING POLLUTION IN REAL TIME BETTAIR® STATIC NODE FEATURES • Custom electronic and mechanical design • Dust tight and water resistant • Low-power consumption electronics • Wireless and wired communication • Up to 5 days back up battery • Platform analytics BETTAIR® AIR QUALITY MONITOR MK2 SERIES MEASURES THE LEVEL OF POLLUTION ON AMBIENT AIRADDING VALUE TO AIR QUALITY MEASUREMENTS The bettair® static nodes are a novel device that permits, for the first time, the mapping of air pollution with high accuracy and in high resolution at a previously unimaginable scale. The bettair® network provides invaluable insights about how to mitigate air pollution. The bettair® static nodes can measure up to 12 air quality indicators as well as ambient noise level and other environmental parameters. With default configuration, the bettair® static node can measure the most common gaseous pollutants: nitrogen dioxide (NO2), nitrogen monoxide (no), ozone (O3) and carbon monoxide (CO). In addition, the nodes also measures particulate matter (PM1, PM2.5 and PM10) in the ambient air. The accuracy of the measurements provided by the bettair® static node is based on advanced proprietary algorithms that enable parts per billion (ppb) measurements with similar accuracy than traditional air quality monitoring stations but at a fraction of the price. The algorithms compensate for the impact of the different ambient conditions as well as sensor degradation due to aging. This removes the need for costly gas sampling and maintenance equipment. The lifetime of the sensors that compose the bettair® static node is of two years. Within this period, the quality of the data is guaranteed. After the two years period, the sensors must be replaced. This is easily done by replacing the bettair® sensor cartridge. The cartridges do not require calibration. The bettair® platform shows data of each device and heat maps of the zone covered and it can be connected with other platforms in an easy manner. Our RESTful API allows to connect our platform with any proprietary or open-source platforms.
