Compact Weather Sensor for Temperature, RH, and Barometric Pressure
The MetSENS300 compact weather sensor measures air temperature, relative humidity, and barometric pressure in a single, combined instrument mounted inside three double-louvered, naturally aspirated radiation shields with no moving parts. Temperature, relative humidity, barometric pressure, absolute humidity, air density, and wet bulb temperature data are provided. The MetSENS300 is compatible and easily integrated with the MeteoPV Solar Resource Platform and any Campbell Scientific data logger using SDI-12, RS-485, ModbusRS-485, or NMEA RS-232.
