all my thanks goes to a friend mr.lloyd, who introduced me this site.
i am trying to fly a kite..
while flying a kite or helium filled balloon, i wanted to capture the wind speed at different height, so the weight of anemometer should be less?
i have a Turnigy Mini Anemometer (Wind Meter), which is a comfy tool to fly along with the heliyum balloons, but dont know how to transfer the data's from it to wifi device and transmit/receive them at ground.
That's not too high for wireless, the only things about it is you basically will need double the suplly
one up top and one down to receive and send to the computer,
if you want it immediatly then it makes senses but if tneres no rush an sd card can store a ton of data, then just plug it in and look at the data all at once in a nice file
the only wireless I have used is the nrf24l01 (10$ a pair on ebay) and it seems great for me althoigh I've only tested it maybe 10 meters, but I imagine in open air it should work fine 30 meters
After looking quickly at the specs of the electronics, I would maybe suggest bypassing that and hooking an arduino up directly to the hall sensors
The only use for the microcontroller it has is to read and calculate rpm, the arduino can do that and datalog/send the data all itself without more complexity of getting the reading off the other device
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 and
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
Fitting the anemometer with a wind vane sounds like a plan to keep it pointing into the wind, you can try it out on the ground easily enough.
If the balloon/kite is tethered, not flying around, and the anemometer is suspended below it then maybe its not too much of an issue. I guess you just have to try it and see if you believe the results. You could maybe release something light from the balloon/kite and measure its speed of travel to try to confirm your anemometer reading.
As far as getting data out is concerned I am a newbie not an expert. I would have chosen something with a ready to use interface but that is just because I know nothing about electronics.
Okay on sunday i did visited few neighbouring areas, it was too tough for me to hold the anemometer and record update in a scribbling pad, atleast is there a way i can do datalogging using the handheld turningy device?
