Remark

1. Supplementary description of wind speed and direction parameters: the wind speed and direction can be measured by ultrasonic principle, and the instantaneous wind speed, instantaneous wind direction, average wind speed, average wind direction and other data can also be output. The optional electronic compass is used to measure the apparent wind speed and direction data, and the GPS is used to calculate the real wind speed and direction.
