There is no harm. The test tower is similar to an anemometer at a weather station. It only measures and collects the atmospheric environment at the base of the tower and its surroundings, then sends the data strictly via digital radio. Speaking, it is more like an automatic weather station and will not affect the environment. This cannot have any impact, otherwise it will affect the accuracy of the data, so it will have no impact on people.
Although I've never done it, I thought about the general framework
The first is the speed measurement mechanism
1 A base which can rotate 360 . degrees are required. There is a baffle on the top to detect the current wind direction
2. A blade that rotates very sensitively is necessary to detect wind speed
The final test will pass. An infrared tube or Hall element is used for detection. The direction isrelatively simple, just look where the cap is. For wind speed, you need to drive a shaft to rotate through the blades, detect the rotation speed (you can use an encoder or infrared detection), then convert it to wind speed. .
The description is not very clear, but the general idea is that we think of wind turbines, haha
