Arduino based LCD display for Wind Instruments.

IMG_20140602_085412I have been working on a separate wind speed and direction instrument  based on an Arduino controller and a simple numeric LCD display. The Arduino is hooked up to a rotary knob encoder  to allow configuration  for the RPM  factor and impulse count of the attached anemometer.  The vane input is a simple 5V range ADC input and the firmware can learn the range and offset from the vane output.

The display updates at a one-second interval with a 10 minute window for gust peaks.  With the 8 pole opto- interrupter in the anemometer the resolution is about 0.3Mph.

I designed this as a handy tool to check out the function of wind trees and because of that I have not made a housing for it, but if there is interest, I could create an Arduino shield and maybe add a Barometer/Temp sensors plus a SD card to the mix to make it something a storm tracker could put together.

  1. Hi! I want to build a mini station for this project. But I dont know where to buy wind speed and direction instrument. Could you give a link for this. Thank you very much.

    • You can get the Wind sensors from me. Move the cursor over the “Order” tab and pull down, you should see an expanding tab with a “Contact me first” and an “Order Now” box. Move the mouse carefully over to the “Order Now” and click there. You might also want to get the PVC pipe mounting hardware if you decide to order.

    • That’s the mini station I’m interested in : I don,t want to go to internet to see live data. For me just add the temp and humidity and I can take car of the housing … tel me as soon as it’s available.

      • I’m hoping to get back to this Arduino version soon, so I can finish and document it properly. I have been busy with other projects lately and it has been sitting in the back of the bench. Gary
