Mierij Meteo MMW005 Weather Station

The Solid State Wind Sensor uses a temperature sensitive element to measure wind direction and wind speed. The sensing element consists of a specially designed ceramic plate which incorporates an IC. The IC temperature is maintained at a constant value above ambient temperature.

Two pairs of thermocouples are mounted on the IC at right angles. If there is an airflow, the thermocouples measure the temperature difference over the IC surface. This is a measure of the wind speed. Guide discs ensure that wind passes the sensor in the right way. Mathematical processing by microprocessor and a signal conditioner results in a RS422 signal for windspeed and wind direction according to the NMEA 0183 standard.

The wind sensor has no moving parts, which guarantees a long lifespan with only a minimum of maintenance.
