Sensor Network for Environment Monitoring: Water Quality Case Study

The challenges of climate change, population growth, demographic change, urbanisation and resource depletion mean that the world’s great cities need to adapt to survive and thrive over the coming decades. Slashing greenhouse gas emissions to prevent catastrophic climate change while maintaining or increasing quality of life can be a costly and difficult process. Two factors that directly affect the life quality in the XXI century cities are the water and air quality that can be monitored using the combination of low cost sensing modules, M2M and IoT technologies. In this context the work presents a wireless sensor network architecture that combines low cost sensing nodes and a low cost multi parameters sensing probe for reliable monitoring of water quality parameters of surface waters (lakes, estuaries, rivers) in urban areas. An extended description of the water quality measuring channels and several elements concerning the wireless sensor network implementation are included in the paper.
