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.
