Location
The EQ demonstrator consists of an administrative WSN network allowing real time monitoring of environmental parameters. The installation will be done in the city of Pisa in the suburban area of Montacchiello.
Context
The distribution, the number and the type of sensors, have to be in agreement with the local authorities.
In this context, the types of parameters to extract and the area to monitor have to be significant for the environmental analysis. Depending on these constraints and according to the cost and the covered area we expect to deploy between 10 and 20 nodes
The WSN-based system will be able to capture parameters necessary to provide dynamics of supervised area. These parameters are used for real time analysis to be processed by the application server, or collected to be post-processed in other labs and compared with different types of reference scenario for pollution or other activities.
Even if the WSN data are less accurate than current fixed stations for environmental parameter analysis, the low costs and modularity make the whole WSN data more reliable and customizable in terms of dimension of the covered region and of information granularity.
Capabilities
The demonstrator offers the following features:
- Collection of geo-located data in real time
- Consists of independent nodes capable of measuring different parameters such as: air quality (C02, N02, 03, etc.), noise levels, light conditions, and temperature fingerprints
- Full coverage of the deployment area selected in the municipality of Pisa
- An application server for storage and processing of data
- An intuitive user interface accessible through the browser for authenticated users
- Interactive notification alert on a web browser interface.
- Displaying of data on different formats: interactive on maps, using logs or showing graphs
- Self-powered nodes with rechargeable batteries through solar cells.
System benefits
- This product could be a good compromise in term of cost and results with the current analysis systems.
- In addition it should be considered a good equipment to monitor the environmental conditions and quality and to foresee proper structural or temporary alternatives.
- This WSN-based system is very resilient in relation to the WSN characteristics of spatial distribution and redundancy. For these reasons a small failure have a small impact on measurements accuracy
- The demonstrator will use commercial motes and sensors. Thanks to the low-cost hardware, the little need for maintenance, easy connections (power and network independent) and great modularity of the system, we expect to be able to use this WSN system in other cities or different scenarios (e.g. rural areas or areas of crops
