We can add parameters: temperature, humidity, air pressure, rain, UV, solar, luminance, PM1.0/2.5/10 on all of those anemometers and make them as all in one weather station. All parameters are flexibly optional.

For minimum budget, I would recommend you HY-WDC2E.

To pursuit best performance, HY-WDS2E is recommended.

For moderate budget HY-SA3E is the most suitable one.

As for UAV,Unmanned Aerial Vehicle, drone, HY-SA2E is ideal one.

Comparison of rain module.

Accuracy of radar and piezoelectric module is same. ±10%.
