Also, I need to replace my temp/humidity sensor since it often will give errors when I read from it. That’s why there are often gaps in the chart for temp and humidity. If you pick a longer timeframe (other than hour), you can see I’m getting some data.

Wow, the work you’ve done with your boards look great! Congrats on getting your anemometer working.

How are you debouncing the anemometer signal? I first thought I could do it in software, but given how fast the pulses were coming in, I thought I would miss it if I did it in software. So I found a debounce hardware circuit that seems to work really well. I have no engineering qualifications and am a total amateur, so I’m not sure if it’s the best way to implement it. But it seems to be pretty close to the readings from a local airport.

My prototype weather station has been running pretty continuously since January. I used a ESP32 with LoRa as a gateway, and send readings every 20 seconds to my hosted MySQL database. I also built a Angular web app to display the info.

Here’s a link to the site. I documented my setup in About section. I’m surprised that the thing hasn’t shorted out with the rats nest of wires.

If you look at the Battery chart and select The Past Week, you can see how the battery charges and discharges over time. It’s pretty clear that I didn’t need a solar panel as big as I used (2W / 6V, 5.4″ x 4.4″ x 0.2″).

Sounds like an interesting project!

I now have an anemometer working with a non-LORA ESP32 board I have, and it was a bit of work to get it functional but I’m happy with the results. If you do wind up adding an anemometer, I would recommend going with a hardware approach to debouncing. Without a debounce, the readings were not usable. In my opinion, using a software debounce approach won’t work because (depending on what your debounce delay is), you wouldn’t be able to read higher wind speeds without dropping signals.

I based my system on these two videos, although I did have to change the capacitor and modified the software a bit, but still highly recommended:
