Smart City project in Santander to monitor Parking Free Slots
SMART SANTANDER project, which has been developed by several companies and institutions including Telefonica I+D and University of Cantabria, aims at designing, deploying and validating in Santander and its environment a platform composed of sensors, actuators, cameras and screens to offer useful information to citizens. 375 Waspmotes have been deployed to monitor parking free slots.
The city of Santander was divided in 22 different zones. Each zone had a Meshlium to gather the data from the sensors and the number of sensors depended on the area to cover. Each zone had different network parameters, creating independent networks that work on different frequency channels not to interfere with each other.
375 Waspmotes were deployed in different locations within the city of Santander, measuring magnetic field to detect whether a parking slot is free. Magnetic field sensor is connected to Waspmote through the Smart Parking Sensor Board.

These sensors detect the variation of the magnetic field generated by a car parked on it. To do that, the sensor is buried under the surface of the road inside a waterproof casing. The hole is closed using a specific material and it is barely detectable at a glance.

The information is sent periodically to the repeaters and then to the Meshlium, which stores the data and updates the information available for citizens. There are a series of panels located within the city of Santander to indicate the number of free parking slots. This information is updated every 5 minutes to allow the citizens to find a free parking spot in the shortest time.

The status of the parking slots is also updated in a map for being consulted by citizens before go to the city center.

As a result of this project, environmental parameters can be monitored for further study as well as citizens can also know free parking slots within Santander’s city center. Furthermore, SmartSantander project is a large-scale network for experimentation that allows researchers from all over the world to test different algorithms in a real environment.
