Abstract Information :
Recent advances in sensor technology have resulted in new air quality monitors that have the potential to provide an informative addition to reference methods, as they allow air pollution monitoring to be performed at a lower cost and with a higher spatial density than currently possible. This new technology is being implemented by a wide range of users, from researchers employing sensor systems in hybrid networks to citizen scientists carrying out projects of local interest to communities.
Standardisation to underpin such measurements has been slow due the need to accommodate the complexity of low-cost sensor performance. The European Standardization body, CEN, only recently published a Technical Specification for gas sensors and another for particle monitors is expected for the end of 2024.
The Department for Environment, Food and Rural Affairs (Defra) commissioned the National Physical Laboratory to develop a code of practice for the use of low-cost sensor systems. The resulting document, PAS 4023, was produced following discussions with stakeholders, as well as review by an invited scientific steering group and public consultation.
This presentation discusses the highlights of PAS 4023 and its key findings on quality assurance (QA) processes needed to generate fit-for-purpose data from these novel sensor systems.
