Severe weather conditions can form serious hazards for large outdoor events, such as festivals. To prevent dangerous situations, continuous monitoring of weather conditions is of importance. The system monitors the weather accurately and immediately by measuring wind speed, wind direction and temperature. It is powered by solar energy, and uses a 3G connection to store its data in the cloud. The data is accessible via any mobile device or web browser, where the average wind speed and the gusts are shown as well. The system is resistant to the most extreme weather conditions and is easy in its use. The system has a GPS atenna, which allows contuinuous track and trace. The measurements statistics are conforming the latest meteorological standards, making this system very reliable. Optionally, the standard sensors can be upgraded to industrial class MW35/MW36 sensors. We can also provide a robust transportation case.
