The MetSens550 is a compact all-in-one weather sensor that measures wind speed, wind direction, air temperature, relative humidity, and barometric pressure. It also supports connection to a tipping bucket rain gauge for rainfall monitoring. With an integrated electronic compass and robust design, the sensor provides accurate weather data and easy integration with the MeteoPV Solar Resource Platform and Campbell Scientific data loggers.
