Overview

The MetSENS550 compact weather sensor measures wind speed and direction via an ultrasonic sensor, as well as 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. An integrated side connector allows users to connect a tipping bucket rain gauge. An integrated electronic compass provides apparent wind measurements. WMO average wind speed and direction and gust, temperature, relative humidity, barometric pressure, absolute humidity, air density, wet bulb temperature, rainfall total, and rainfall intensity data are provided. The MetSENS550 is compatible and easily integrated with the MeteoPV Solar Resource Platform and any Campbell Scientific datalogger using SDI-12, RS-485, ModbusRS-485, or NMEA RS-232.
