The MetSens300 is a compact weather sensor that measures air temperature, relative humidity, and barometric pressure within a single integrated unit. Housed in naturally aspirated radiation shields, it provides accurate atmospheric data, including absolute humidity, air density, and wet bulb temperature. The sensor integrates easily with the MeteoPV Solar Resource Platform and Campbell Scientific data loggers through multiple communication interfaces.
