Over the past few months we've been running a pilot with air quality sensors placed inside BT InLink stands. These sensors capture and send data every minute. This data is a snapshot of the real time data.
- Nitrogen Dioxide - PPB
- Carbon Monoxide - PPM
- Relative Humidity
- Temperature
DEFRA data is normally in ug /m3, the formulae to go from PPB to ug. It is temperature dependant but a rough approximation of conversion is times the PPB by the factor below to get ug/m3 (see link below for more details).
- *1.88 at 25°C
- *1.95 at 15°C
- *1.98 at 10°C
- *2.02 at 5°C

CSV's hold current data for the last 30 days and this is updated daily to keep the last 30 days cycle and Zip files hold historic data for Air Quality Monitoring.
Update 10 January 2020
The devices are being returned to the factory for an upgrade, as a result there may be gaps in available data for the next few weeks.
