Project Brief
Sea Water Analytics is a Spanish project based on the measurement of physicochemical properties of the water on the beaches, created with the objective of supporting intelligent tourism and the growth of Smart Cities.
The waters of coastal areas are permanently punished by wastewater discharges, uncontrolled and illegal discharges, which aggravate the climate emergency declared in January 2020. The infrastructure of coastal cities is not prepared to allow these localities to guarantee the quality of their waters, which are the main resource for attracting tourism. They are exposed to illegal or uncontrolled dumping that can damage their main tourist attraction resource, their coasts. This project was born to give technological support to these localities, providing reliable information about the chemical quality of the water, the occupation of the beaches or the sighting of jellyfish.
Proposed solution
The infrastructure that allows these capabilities is an advanced computer system formed by three elements:
A large network deployment of marine buoys provided with a set of chemical sensors of acidity, salinity, oxygenation and temperature at a certain depth. Then thanks to Thinger.io’s IoT technology they are sent and stored in the cloud, then using the Node-RED plugin, all the data is retrieved in real-time from a data bucket to be enriched with information obtained through Sea Water Analytics’ APP and forwarded to the analysis system.
Over the total data set, we apply advanced analytics and sentimental analysis to obtain a quality Index that is displayed to the user, in addition to other information that helps to improve their User Experience on the beach.
The use of Thinger.io is key to the Sea Water Analytics infrastructure by enabling scalable deployment and management of the devices through HTTP Device technology, where the callback has been automatically configured to apply pre-processing and storage of the data. As a result of all this system, citizens and tourists from coastal cities can download a mobile application from which they can obtain all the information in real time, provide jellyfish sightings and make assessments on the state of the beach.
Visualization
The data can then be sent within one hour to the user app that displays the values that each municipality chooses to monitor. Data interpretation currently requires a member of the Sea Water Analytics team, comprising the co-founders and part-time staff lent by its two partners, though it will be automated in the future. As more data is accumulated and stored, its interpretation becomes ever more reliable.
