Sensor calibration of the Dustbox is undertaken in relation to the LAQN Marylebone reference monitor and through techniques of cross-comparing individual sensors in test and monitoring locations. Sensors will be calibrated throughout designated monitoring periods and in relation to monitoring sites. In some cases, Citizen Sense may make available ‘raw’ LPO data as well as ‘converted’ data so that sensor data can be read in relation to official air quality guidance on limit values. Values can change in relation to ongoing calibration processes, and Citizen Sense does not assume responsibility for these changes.
All sensors will have variability and may drift over time. We look at and compare the variability of the sensors that we have distributed throughout the monitoring period during which sensors are in use. If you have two sensors next to each other it is useful to look at the patterns and see if they match. Numerical readings can be higher or lower across multiple devices with shared patterns depending upon the sensor variability and proximity to emission sources.
