Using our IoT air quality platform, SMA has leveraged the ability to enter the Smart City business. This is a suite of open APIs and a compact yet powerful Air Pollution Monitoring System that provides air quality indicators and metrics to public administrations and citizens, both via the web and with physical displays.
Monitor air pollution in public city parks, giving citizens the opportunity to know how the air quality is, measured in real time, thanks to a light indicator. This indicator is mounted in place and shows the KPI in 3 different colors: green, red and yellow. The government is able to access all sensor-specific information collected throughout the day at hourly time intervals.
MOLO17 engineers and its partner Eurotech managed to overcome the challenge by providing a customized ReliaSENS, an IoT gateway created specifically to collect and analyze air quality parameters, electromagnetic fields and ionizing radiation, which connect to our IoT platform on Amazon AWS. Using remote commands, we were able to interact with an Ethernet relay board that controls the LED indicators mounted on the remote display.
Air Pollution Monitoring System from Eurotech
We chose Eurotech’s ReliaSENS 19-15 air pollution monitoring system, connected via 3G to the Amazon AWS public cloud. All gateways are supplied hardened and remotely manageable via Device Management Cloud.
Displaying the air quality index in parks
A customer-specific algorithm can be applied to process the air quality index, a 3-step indicator translated into a color scheme that automatically explains the air quality from good to bad: the colors green, yellow and red for a citizen’s view. We process the algorithm in the Cloud, where the data has been securely stored, then send the command to the gateway where we have connected a relay board, that speaks ModBUS and which drives the 3-led light indicator mounted on the pole.
Citizens are able to see what kind of air pollution is happening in the area, customers can integrate the collected air pollution metrics into their systems thanks to our Open API approach. Open API is a web UI that allows you to inspect metrics and export reports by filtering data from specific times in the past.
We only know a fifth of what lives in the depths.Everything else is left to explore.
