A very smart and fully autonomous anemometer that can be useful for our hobby. It features a compass and GPS, and connects automatically to a global cellular signalling network dedicated for the internet of things. This technology is developped by a french company located in Toulouse and called Sigfox (http://sigfox.com/en/).
It uses UNB (Ultra Narrow Band) based radio technology and requires a very low energy consumption. The SigFox network currently covers France and Spain, but I understand that some new countries are developping the network. The "Pioupiou", name of this connected anemometer (pioupiou.fr), has been designed and developped in Grenoble by a paraglider pilot. It costs 325 Euros and includes the life subscription (40 euros) to the signalling network. Once installed, it calibrates and then connect to the network and start to talk over the network. Its battery can last 3 to 4 years before to be replaced. From any internet browser, it is easy to reach its dedicated web page and get the wind direction and force with a history of 2 hours. Our club invested in one unit that has been installed today on our local slope. I can now know the wind on the slope before to devide to go there !
