Five sensors were installed in the parking house Färgaren in Lund so that participants in the SOM project could try out good ways to detect and present vacant parking spaces. Sensors were deployed in five places -- a parking space for people with disabilities, a motorcycle parking lot, a charging post and two regular spots.

Participates in the project Lund Municipal Parking Company LKP as sees opportunities with new technologies to teach us and improve the business.

The technology tested for transmitting sensor signals was Bluetooth Long Range.

“It is difficult with signals in a P-house because it consists of thick concrete and rebar,” said sub-project manager Johan Lindén from Mobile Heights, California. Bluetooth Long Range is a new technology in the testbed and I haven't heard of others testing in the way that we do this. The technology fits well with a radar sensor from the lund company Acconeer and it is the one we have chosen to test in the p-garage along with Bluetooth.

The project was used Acconeers IoT Module XM122, in which a small and low-power radar sensor is combined with a processor and components for connection via Bluetooth. The IoT module is round with a diameter of 33 mm and supports, for example, Bluetooth 5, Bluetooth mesh, Zigbee and ANT. The sensor can measure distances with high precision and has a high frequency of updates.

During the installation, representatives from several companies were on site to make the connection work together.

- What we at MiThings contribute is the implementation of communication between the parking sensor and Sensativas Yggio back-end. It involves the parking sensor detecting a car, sending data over Bluetooth Low Energy (BLE), along with other sensors via a gateway over the mobile network (LTE/CAT-M1) to Yggio, Knut Mårtensson told MiThings.

The signals were connected via Sensative's sensor platform Yggio. There, for example, Lund Municipal Parking Company (LKP) can retrieve data to see how the occupancy rate looks while the company AppArkingsPOt can use the same data to real-time data in their app. At the same time, Power ringsn find out if it is busy at their charging locations and report it to the Charging Map app.

“It would also be conceivable that an app for people with disabilities could take data to its platform to show available parking spaces,” said Johan Lindén.

The project also made a bookable parking space at the water tower outside the Mobile Heights Center. There, ApparkingSpot will rent out the place via its app as a test.

What was the result?

• The deployed sensors report in as they should to Yggio and the project has delivered a working solution for sensors in parking lots. The values are then passed on to ApparkingSpot, Kraftringen and LKP so that they can use the data to know if there is a car parked on the spot or not and so that they can use the data to create their own services.

• In the trial, AppArkingSpot has tested having a bookable parking space in a parking space at the water tower. In the parking lot there is a sensor that communicates with the AppArkingSpot app where customers can make their reservation. The experiment has enabled ApparkingSopt to develop a complete parking service that works.

How is the project taken forward?

From the data reported, statistics will be produced for parking at the various locations.

The parking project in the parking house Färgaren is being continued and the work will continue within the project Lund Open Sensing City.

Facts sub-project Monitoring of parking spaces

The project is a sub-project of the SOM project is part of the Strategic Innovation Programme for the Internet of Things, IoT Sweden, which is funded by Vinnova. Anders Trana at Future by Lund was the project manager for the entire project. The project started on 1 September 2017 and ran until December 2020.
