Tracking weather conditions is important in many industries, including agriculture, transportation, public security, forestry and environmental protection. Weather conditions often vary over short distances and therefore only local measurements are accurate and useful. The current weather is the most interesting, but for prediction models and algorithms long-period recordings are a necessity. All this has to be provided without increasing the workload of the user.
