README
README.mdWeatherStation
The goal of this project was to build a cordless personal weather station that can be put in your own backyard. The weather station sends data to a server and you can analyze, store and use the data in anyway you want.
This project includes c file to upload to the microcontroller, the server files used to store data in the sql database and display it to the website, and the schematic and pcb files for the actual hardware.
Hardware
The Mircocontoller I used in this project is the esp32. A more generalized arudino code file is uploaded to this repo also. The weather station reads temperature, humidity, and pressure through a BME280 chip. It has a water sensor to sense if it is rainig. It uses the solar panel to tell how bright/sunny it is outside. This solar panel is also charging the lipo battery that it is powering the weather station. There is a uv sensor that tells us the uv index. There is Wind Sensor Rev P made by Modern Devices that is able to measure the windspeed. Also, there is a PWM5005 sensor which measures the air quality. The esp samples each sensor input then sends the data wirelessly to the server.
Server
The server stores the data from the weather station and puts it in a mySQL database. The server also hosts a website where a client can interact with current and previously stored data.
Future
This project is still in progress but the hope for the future is to implement an machine algorithm to try to forcast the upcoming weather.

Questions
How big is the WeatherStation PCB?
It measures 60 × 60 mm and has 4 copper layers, 4.69 mm thick.
What parts does the WeatherStation use?
84 parts, built around the ESP32-S2-MINI-1-N4, MC33063ADRJR, BME280 and 74LVCH1T45GW. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the WeatherStation KiCad files?
From the LStranc/WeatherStation repository on GitHub, at the commit this page was made from: the board is PCB/WeatherStation/WeatherStation.kicad_pcb and its schematic PCB/WeatherStation/WeatherStation.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the WeatherStation design in my own project?
Its repository states no licence, so its author keeps all rights: ask LStranc before reusing the design.
