Outdoor applications, depending on where you are located can be extreme. Indoor or in-vehicle applications may also experience wide temperatures whereby ordinary PCs are incapable of operating. Buses or aeroplanes after a day under direct sunlight can heat up to 80˚C, or if left in the winter blizzard can freeze to minus 30˚C or lower.

Refineries are also places where extreme temperatures are encountered. However, in recent years, wide temp industrial or embedded platforms have found their place in building automation and outdoor smart devices that are required to be up and running regardless of the season.
