The Windmate WM-300 measures wind speed and direction, temperature and humidity. It is unusual in that its humidity sensor is is self calibrating to maximise its use in the field.
Wind direction is measured using the inbuilt wind vane and digital compass to give wind direction, cross and head-tail wind readings digitally and in compass points.
