ULTRA Urban - new air quality service

Fun fact: Cleanest air in Somerset House was observed during the Royal Wedding!

· Blog

We are about to launch ULTRA Urban, an environmental monitoring service that is going live in Manchester and Amsterdam where our clients get insight on air quality specific to their areas of interest.

We also have a setup at our office in Somerset House in central London, where we monitor both indoor and outdoor air quality, and we thought it'd be interesting to share some of the things we found from the data.

This device can measure air quality on a two minutes frequency, allowing to have information about the air you breathe instantaneously. They also work with a wide range of communications protocols, such as LoRa, Sigfox, WiFi and bluetooth!

We have an ULTRA Urban sensor outside of Somerset House, facing Victoria Embankment, and we have the same sensor indoors. Our air quality expert Antoine explains what we see if we just leave the sensors running for a few days:

  • On average, the air quality inside the building is 70% cleaner than outside. You can observe the difference in the graph below, where the lighter lines represent pollution outside of the building and the darker inside.
  • The worst air quality is observed on Saturday nights (11pm-8am) and Monday mornings (2am-7am). We think that the Saturday nights' pollution may be caused by nightlife induced traffic in combination with road traffic flow being redirected.
  • The lowest levels of external air pollution were observed on Sunday afternoons (4pm-9pm) and during the Royal Wedding! 

Of course, this is just a behind-the-scenes look into what we see when we have two sensors running for a few days, so imagine the insight we get when we have an entire part of a city connected. We'll make sure to keep you posted on the findings in Manchester and Amsterdam as we deploy in those cities.
