Smart life preservers keep our waterfronts safe

In the smarter city, technology helps keep us safe. Helsingborg is the world’s first city with life preservers that automatically alert our maintenance team when they’re removed from their posts – thanks to connected magnetic sensors.

When Development Engineer Andreas Hall, who’s working to digitalise Helsingborg’s public spaces, realized that magnetic sensors could be the key to realizing this project, he scoured the globe and discovered that the right sensor for this job already existed, but in a very unexpected place!

Now we can all depend on lifesaving equipment being there when we need it and enjoy our seaside, creeks and ponds with more peace of mind. And city maintenance replaces missing life preservers more quickly and reduces time and driving distance spent monitoring and replacing them.
