It is early summer, it is hot in the air and a visit to the beach at Fria bad feels attractive. But how hot is it really in the water? Since it's a weekend there might be a lot of people on the beach, can I park my car near Free Bath? How much does the sun take like this in late spring?

I look at helsingborg.se to see how that situation is right now because I know that the city has a fantastic bathing place information that is updated in real time.

In order to offer the opportunity to give the customer the greatest benefit before their visit to Fria bad, a weather station will be located at Fria bad. In addition, buoys with temperature sensors will be placed in the water. Both the weather station and the buoys communicate with the LoRa network that Öresundskraft has built in Helsingborg. Data from the sensors can then be published in a variety of digital forums, for example helsingborg.se and on the digital information signs at Fria bad.

In addition to the sensors for measuring temperature in the water and keeping track of the weather situation, the lifebuoys will be connected. We also want to try to connect the defibrillators along the beach. To get updated information about the parking situation, data from parking meters and parking apps can be used, as well as satellite images that are available as open data. If the car park is fully occupied, the street networks around the beach are full of parking cars, the customer can get a suggestion for a suitable bus to get to the beach or a suggestion to visit another of the city's beaches instead.

In the footsteps of the pandemic, it is also important that the distance required to reduce the risk of the spread of infection between people is maintained. By counting the number of people on the beach, we can assess whether a beach is "full" or not. The count can be made through small detectors that are placed at the entrances / exits that are in the wall along the beach promenade, a sensor on each side of the wall allows us to see if you go to or from the beach.

A similar approach to giving the customer such comprehensive information and help prior to their visit to the beach has not been done anywhere else as far as we know. The information from all sensors and open data can also help the city's contractor to manage the operation and maintenance of the beach in a good way that provides increased benefit for the customer.

Impact target

Increased service and security for the city's residents and visitors by using sensors in new ways.
