Abstract Wireless air quality networks are being deployed throughout North America and Europe. Deployment of both mobile and fixed site networks in Cambridge, Valencia etc. as well as Heathrow airport have taught us the value of fine temporal and spatial resolution, required by the urban fluid dynamics modellers.
Additionally, mobile mapping with GPS has shown the importance of mapping in real time whilst also referencing to AQMs for data that is accurate and on time. Trials with these low cost networks located adjacent to AQMs shows that these networks are not only trending networks but also reliable absolute measurements.
We will demostrate the combined capabilities of:
1 ppb capable amperometric gas sensors
2 low noise potentiostatic circuitry
3 Geotech capability to broadcast measurements with required time resolution
3 Cambridge University data analysis which ensures reliable sensor data transfer into useful citizen data.
