Using the map
The map is divided into hexagons (six-sided shapes). Each one shows the average (median) reading from sensors in that area.
You can choose what to view, such as PM10, PM2.5, temperature, humidity, pressure, or overall air quality (AQI).
The colour scale on the left shows what the values mean.

Click to explore
Click on a hexagon to see a list of the sensors in that area.
At the top, you’ll see how many sensors are there and the average reading.
Click the + next to a sensor to see more details:
- A graph of readings from the past 24 hours
- A 7-day view showing the rolling daily average
(You may notice the first day on the graph is blank—this is normal due to how the data is processed.)

What does this mean at the Humfrey Rooms?
The readings from our sensor give a snapshot of the air quality in and around the Humfrey Rooms. Lower levels of particles (PM10 and PM2.5) suggest cleaner air, while higher levels may indicate increased pollution—often linked to traffic, weather conditions, or nearby activity.
Over time, you may notice patterns, such as changes during busy periods, seasonal differences, or the effect of weather on air quality. This helps us better understand the local environment at the Humfrey Rooms and how it changes throughout the day and year.
