Hi! I am building a weather station with esp32 (in the project arduino nano is being used, just for visuals). The weather station will be able to track:

  • temperature - BME280 (yellow tube)
  • humidity - BME280 (yellow tube)
  • air pressure - BME280 (yellow tube)
  • sunlight - BH1750 (yellow tube)
  • wind speed - green tube
  • wind direction - orange tube
  • amount of rain/rain gauge - red box

how the rain gauge works

how the wind speed is going to be measured

Please note that the models of electronic parts are there just for visual purpose. Some of them are going to be included in the final build , so note that they could be the wrong parts.

At the top (blue box) there is going to be two solar panels (2 x 5w 12v) that are placed in a way so that the falling rain is going to flow on top of them to get to the rain gauge. The solar panels are going to be connected to CN3791 (MPPT) and then to the batteries (4 x 18650). Then from batteries to the LM2596 in order to lower down the voltage so that esp32 can be powered.

I am also going to make an app allowing the user to monitor all the data. Weather station is either going to be connected to the phone by bluetooth, wifi or somehow with hc-12 (not directly to the phone, because phones cannot recive 433mHz signals)

Please rate my project in tinkercad and feel free to give feedback. I most concerned about the rain gauge. Also please tell me if there is a chance to somehow shrink it down.

How is this done?

3

Here to see project model.

Tell me if you would design it diffrently or if I should use other parts.

4

I need to see your code and a schematic. Where are they?

5

I havent done it yet. I am asking about the feedback of the model and the overall idea. Sorry for not fully explaining.

6

Nothing wrong with the idea.
Won't the Anemometer interfere with the rain gauge?
How is wind direction measured?
Is 10W enough to recharge the batteries, especially since the panels are in a fixed position?

7

Weather stations are a popular Arduino project, and plenty of examples and tutorials have been posted on line. Yours seems typical, so do the reading and research.

8

no, I measured the distance and it should be ok
using GY-273 and ball bearing the GY-273 will be moved with the direction of the wind.
Yes, I calculated that they should be enough. My worry is that the rain will somehow damage the solar panels, but I believe they are waterproof.

The issue with these projects is that they dont meet all my expectations which are to be able to power the weather station with solar panels.

10

I've seen several solar powered Arduino weather stations, and some have been discussed on this forum. Solar power is trivial to add to any station.

Use the forum search box to find those threads.

11

Incomplete.

12

Love the TinkerCAD simulation results in the 3D viewer... :laughing:

13

How will you connect wires to something that is rotating?

but I believe they are waterproof

Not all are.

14

That is fun:

simulation

15

I bought something called slip ring. It will rotate the cables.

Then I have to check. I am wondering if putting a plastic foil or glass on top of them will somehow decrease the effeciency of solar panels.

16

Peek of engineering.

17

You might consider this angle encoder, no slip ring needed.
You connect a small magnet to the shaft of the wind vane and the sensor reads the orientation of the magnet.

Yes, I calculated that they should be enough.

Unless you live on the equator the panels will have little exposure to the sun.

You mean something like this? :

I left out the link to the one I was refering to

This one is much cheaper.
