Wind measurement
Wind speed and direction are measured using four ultrasonic transducers. The Wind Gauge measures
the time between the moment a signal is emitted and the moment it is received, along two
perpendicular directions. Wind speed along the N-S axis and W-E axis are then merged using
trigonometric functions to obtain the real speed and the direction.
Displayed measures
Your dashboard displays:
- Last 5 minutes average wind speed and direction. The arrow indicates the wind direction and its size
is proportional to the speed. Light grey dashes around the arrow indicate the dominant wind
directions during the last hour.
An arrow pointing down means that the wind is blowing from the North (N = 0°). An arrow pointing
to the left means that the wind is blowing from the East (E = 90°).
- Maximum wind gust (speed and direction) over the last 10 minutes.
- Maximum wind gust (speed and direction) during the day (since last midnight).
Graphs let you navigate through historic average wind (speed and direction) and gusts (speed and
direction).
