Hello, i have the same problem as Mirko78.. Does anyone have a solution for this?

Niels Bos

This design is using a LiPo battery to drive a 5V voltage regulator. Can't imagine that this will work reliably especially once the voltage drops further.
I am currently working on a weather station using a LiFePO4 cell. These have an operating voltage that fits perfectly into a ESP8266 setup.
I'll upload my design here once it is done.

In some slicers the bracket on the main part will be printed as a separated part.
Normaly no problem cause you can glue it.

But i repaired the file so the main part will be printed as one part.
The file is free for use.

Will these solar panels work work?
Might be better to use a mppt charger module rather than a TP4056 for that solar panel so it get's the most out of that small solar panel

Hi everyone,i made this project,have a problem,the station stop to send data at random time,once send data for 2 hours,once send data for 8 hours,once send data for 20 minutes...it is very boring...can anyone help me?i use the same board in this post and the data is sending for thingspeak account..sorry for my english...i hope anyone can help me,thanks

Do you already have a solution for this problem? I have the same problem.

Hi, I live in a place with high rain and snowfall. Will this casing really protect my components? thanks!

No. Unfortunately rain gets inside easily.

@deba168 please share the fusion 360 files

@deba168

please upload fusion360 files, i want to make changes for my electronics

Can you share the fusion 360 files please?

Is it possible to get fusion file of this project?

There's one fatal flaw in the design: the front of a Stevenson screen is supposed to face away from the Sun, while the solar panel is supposed to angle toward the sun. With this design, either your measurements will be unreliable (box facing toward the sun), or the solar panel will be working at minimal efficiency (box facing away from the sun).

Hello- I did a few revision of the housing and was going to post them once complete. However I have had some issues with the programming. I can not get the script to compile and now the error stops at missing the library at first I was getting the error on the BME280 but found that library. Does anyone have the wire.h missing library needed?

I saw your original article posted somewhere else last year. Curious, I began to read more and your project became the core idea of my own version of your weather station. In mine, I not only use the BME280 for environmental data, but I also have a connection to OpenWeatherMap for collection of local information, such as wind speed and direction. I also added NTP for time. And instead of using a cloud sourced app for the phone, I created an HTTP page to display the data in text format. I also added MQTT to send the data to my Mac, where I run Telegraf, InfluxDB, and Grafana for graphs of battery voltage, temperature, pressure, humidity and dew point. I've gone so far as to create a version that uses LoRa instead of the Wemos mini D1. That version will let me place a node, collecting just temperature, pressure, humidity and battery voltage readings, out in my pasture. All of my nodes use MQTT, so I can use Grafana to visualize all of them. I'm circling back to your project now that I have a 3D printer, a Prusa I3. I like your case, a lot. Thanks ever so much for your inspiration!

Thanks for this object!
I would like to make some minor modifications to the design (move the board holder up and make room for a 2x18650 holder), would it be possible to get the source files?

I like your solar box design with one exception. The print is very long at about 8 hours. This said, if there is a flaw with the print you have wasted hours and filament. The box would be better to be split into smaller pieces this way if anything goes wrong you can simply print the bad part and fix the problem.

Very cool!
Did you conformal coat the boards with nail polish or other clear paint/lacquer to protect the components and solder joints from corrosion or moisture?
