I need to install wind gauges at different locations but don't want to spend $450+ each for more Davis Vantage Pro2's. Fortunately I found this method to connect the Davis anemometer directly to an Arduino:
http://cactus.io/hookups/weather/anemometer/davis/hookup-arduino-to-davis-anemometer Works great! With a bit of modification. That means $130 for a pro quality internet connected wind gauge! The Davis wind gauge was $114 new off eBay <http://www.ebay.com/itm/191951731404>, shipped, from the seller sarafankit2009. Can definitely recommend. The auction description was "Davis Instruments 6410 Davis Anemometer For Vantage Pro Pro2 6152 New". That plus $10 for the Arduino clone and $8 for the CHIP, which is similar to a Pi. I adapted the Arduino code for easy reading from weeWX and made a weeWX driver, posted here along with the Arduino code: https://github.com/wrybread/ArduinoWeatherStation It's currently a bit light on documentation but I plan to build that out. The Arduino weather station is currently uploading through weeWX to a test location: rproductions.org/wind Every time the wind direction indicator turns green it means there was another update. It's using the RealTimeGauge extension. Some questions and issues: - the driver currently gets the wind speed about every 17 seconds even though the Arduino is reporting it much more often that that. When using a Vantage I get the wind about every 2 seconds. Any thoughts on how to make the updates more frequent? - I named the driver "aws", as in "Arduino Weather Station". I'm a bit worried that might get confusing and hard to search for because of Amazon Web Services. Agreed? Idea for other name? - where to place the driver file? Currently in /home/weewx/bin/weewx/drivers/aws.py. - should I make any changes to how it's packaged? Would this be something useful for the main fork of weewx? And FYI I adapted the weeWX driver from the MWS driver mentioned in this thread <https://groups.google.com/forum/#!topic/weewx-user/hB1knRFdSvY> and posted on github here <https://github.com/YannChemin/MWS>. -- You received this message because you are subscribed to the Google Groups "weewx-user" group.
