At Baden Swimming Pool (AG), the lifeguards were constantly pestered about the water temperature in the swimming pools. So the City of Baden took the opportunity, together with the local energy and water supplier Regionalwerke AG Baden, to provide visitors with a useful service via an IoT solution from the Switzercloud.On a wide screen monitor located at the entrance area, or conveniently on any smartphone, bathers can check the current water temperature of any pool at any time. The individual temperatures are sent automatically to the Switzercloud via LoRaWAN© sensors where the data is processed then visualized. This solution shows how the Internet of Things can solve specific tasks efficiently and inexpensively. In addition to the bathers great contentment, operational efficiency is also increased thanks to the elimination of manual measurements & human error. A real added value for all (pool) parties!
