Report this content

Trollhättans Stad has, through a collaboration with Trollhättan Energi AB and iioote AB, placed water temperature sensors at municipal bathing areas to keep track of the water temperatures this summer.

The application is made possible by the leading LPWAN standard LoRaWAN®, which is based on an open standard and is a cost-effective way of communicating with and positioning sensors. The advantages are several with long reach and low energy sensors.

Bertil Moberg, responsible for IoT Solutions at iioote AB says “The collaboration with Trollhättan City and Trollhättans Energi AB will enable many new exciting solutions to improve our society by testing, using and developing future business models and applications within IoT. The radio technology is optimal for applications with a small amount of data and that the electronics are cheaper than in traditional wireless devices. This makes the network perfect for measuring everything, creating smart buildings and cities and locating things, and much more”.

“We are glad to get bath temperature sensors in place before the summer holidays. This is a good service for the local residents who are eager to swim”, says Ida Andersson Social Structure Administration Trollhättan City.

“I am very pleased to see we are offering a solution that is useful for the residents of Trollhättan Municipality. The fact that you can get something that is beneficial to the inhabitants with small means and easy solutions is a big plus, and that it is finalized before the summer holidays is really good”, says Tom Nordal City Network Manager at Trollhättan Energi AB.

"For us it is exciting to be up and running with a cool function that Trollhättan residents benefits from," says Trollhättan Energi Sales Manager Jonas Bergqvist.
