Wind speed gauge - Anemometer

myminifactory

This is just one piece of my weather stations. My Anemometer works fantastically and has handled and recorded winds up to 50+mph so far. It's designed to slide into PVC pipe. I use a simple op amp circuit to convert infrared LED and infrared transistor to a digital signal. The digital signal gets recorded by ESP8266 12E, then sent to the local network and off-site server. You can find a link to the full weather station schematics below. Hopefully they're useful. My weather station reports to http://shermluge.xyz/wx. This is still very much a work in progress but has been collecting data now since December 13, 2017. Over 17,000 records have been collected. The website is still pretty rough, I've hard coded everything, even the graph is just using tables in HTML. I do want to add a lookup history (other than just the past 24 hrs). But compared to the NOAA site, which is near where I live, it's been right on. I'm designing a rain gauge currently. I plan on converting the whole station from spare parts to all 3D printed. Even though it doesn't show in the schematics, some of the sensors are doubled for redundancy and to check each other. Since the original I made back in April 2018, I've swapped out the spinning cups with one made of ABS. I was worried when I made it out of PLA. When we hit temps of 106+ the PLA one drooped, no surprise. The new ABS one works great and is holding up to the high temps. So I would now recommend ABS or PETG or other higher temp material. Updated August 20, 2018 on the 17th when replacing spinner, I noticed it wasn't spinning as smooth as it should. So instead of printing things all over again, I designed a spinner base sleeve that I printed out of ABS and it slid on perfectly, and it works fantastically. The base sleeve is optional.
