Note:

When the maximum wind speed of the last 4s is >=5m/s, the wind speed is
detected by 1s; when the maximum wind speed of the last 4s is >=3m/s and
less than 5m/s, the wind speed is detected by 2s; when the maximum wind
speed of the last 4s is <3m/ s, the wind speed is detected by 4s.

The wind speed reading will be a real-time value (The latest sampling data
will be reporting to the receiver).

The wind gust reading will be the max wind speed in the past 28s.

When the wind speed is lower than 5m/s, the dispersion of wind direction
will increase.
