Wind speed gauge - Anemometer

thingiverse

UPDATED 12-25-2019 This is the latest version, with a newer version available at: https://www.thingiverse.com/thing:4066146 This is one part of my weather stations. This anemometer works fantastically and has handled and recorded winds up to 30+mph so far. It is 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 is recorded by ESP8266 12E, then sent to the local network and off-site server. I've linked to the full weather station schematics below. Hopefully, they will be useful. My weather station reports to http://shermluge.xyz/wx This project is still a work in progress but has been collecting data since Dec 13, 2017. Over 17,000 records have been stored. The website is rough and I've hardcoded everything, even the graph uses tables in HTML. I want to add a lookup history (other than just the past 24 hours). 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 to convert the whole station from spare parts to all 3D printed. Some of the sensors are doubled for redundancy and to check each other. Updated 8/17/18: Since the original I made back in April 2018, I've swapped out the spinning cups with one made of ABS. When we hit temps of 106+ the PLA one drooped, no surprise. The new ABS one works great and is holding up to high temps. So, I would now recommend using ABS or PETG, or other higher temp material.
