accept my apologies for the delayed response.
* How are you going to keep the device pointed into the wind?
it can be done like how small wind turbines are having furling system. like mounting this hand held device andhttp://www.power-talk.net/images/h100-wind-turbine-furling.jpg
similar to the tail portion, we can guide the anemometer to face the wind.?
* How are you going to compensate for the baloon/kite movement affecting the wind speed?
even i do have this worries, but i am thinking atleast if i have some data rather than no data, then i can presume of having a pole and gather complete standard data.
* How are you going to get the data out of the anemometer?
seeking you experts guidance regarding the same,
as winner10920 guided regarding wireless nrf24l01 Module with Arduino, it would be really helpful, again, thinking wague, when there is some kind of data transmitted to the digital display, why not that can be transmitted through arduino
