The WS501 weather station is a compact weather station for measuring Wind Speed & Direction, Air Temperature, Relative Humidity, Air Pressure and Solar Radiation. Outputs are in RS485 in the following protocols: ASCII; UMB; SDI-12; and ModBus. Available with low-power setting for remote stations with solar power and can be integrated with various loggers for a complete custom remote weather stations.
