The CS215 is temperature and relative humidity sensor manufactured by Campbell Scientific Ltd. This probe uses a Swiss-made digital humidity and temperature element that provides good measurement accuracy and stability. The elements are based on CMOSens® technology, which have been tested for more than two years in Alpine conditions where they were shown to work to their specifications in extreme weather. | |
