Sensor network: data validation pilot

Team: AirPublic

Formed after winning the UK Climathon in July 2015, AirPublic will install Internet of Things (IoT) enabled networks of mobile pollution sensors on Gnewt Cargo delivery vehicles to generate high-granularity, real-time data of air pollution. AirPublic will use the Sensinact tool to integrate mobile air quality sensors and test the IoT facilities of the Organicity platform. Up until now, many small sensors have not produced reliable data; the aim of this experiment is to take steps towards producing data that can be taken seriously by policy makers, planners and the public and enable them to make informed decisions about air pollution.

“We envision a near future when technology will allow ‘smart’ and dynamic decision making by all stakeholders in the city, from the public to policy-makers alike. This context-rich scenario could enable inefficient, wasteful, and polluting systems to be transformed, creating a better quality of life for everyone. In order for this to happen integration and collaboration are key and these experiments are a step towards this.”

Their Process

Components on the breadboard.

IOT sensor prototype V1.

IOT sensor Prototype V2

Testing Prototype V1 in a central London location.

Precision colocation, recording sensor reactions.

Analysing temperature and humidity data.


Experiment Outcome

Visualisation demonstrating the density of data point coverage achieved by just 9 vans. This proves our install proposition has value in collecting data.

Our data compared to KCL annual NO2 map modelled from the LAQN data, the dots represent where a van passed at least 20 times.

What happened & What’s Next

  • AirPublic is now looking for partners and funds to carry out a trial using more units, to test the use case of our system for scoping or monitoring to inform specific interventions to tackle air quality. It would also allow us to develop our data post-processing models in a larger data environment and further improve the accuracy of measurements.
  • During 2017 we were shortlisted for the Sustainable City Awards and will showcase at the Hello Tomorrow Summit in Paris.
