Ambient Environmental Sensor Network

Assessment of Noise and Air Quality at a high spatial

resolution;

Aims:-

High resolution sensor network and data collection service

Quantification of population exposure to pollutants

Production of data sets that will enhance decision making processes in

relation to environmental management & improvement of quality of life

Identification and making linkages with sources of pollutants

Encourage citizen engagement and feedback

Making real time data available to the citizens to inform

and modify behaviour

Mapping of pollution concentration levels in Dublin

Assist in research

Challenges Facing Deployment of Sensors

Finding Suitable locations that include: -

• Power

• Representative of area being sampled

• No dominant source

• Sensors require to be inexpensive

• Ability to calibrate system

• Able to communicate remotely

• Secure & reliable data storage


Dublin City Council

Challenges re Data Handling

•How data is to be presented

•Decide whether to release raw or calibrated data

•How to quality control the data

•How to ensure data is accurate

•How to ensure data is readily accessible.

•How to make information easily understandable
