a simple weather station using the atmega3280 microcontroller in kicad 10
This project showcases a very simple weather station using the atmega microcontroller and DHT22 Digital Temperature Humidity Sensor and an SSD1306 1.3 inch 128X64 OLED LCD Display to show the status all powered by DC Power Socket Female PCB Mount DC-005 Barrel Connector 5.5x2.1mm. The atmega chip is u can say the brain of the thing that reads data from the sensor and shows it to the screen. the dht sensor can detect how cold or hot it is outside and the humidity level and the screen basically shows us that data. and lastly the barrel jack transfers power to the parts.
The main motive behind this project was in my country the weather is kinda dynamic, by i mean few days ago it was blazing hot now its raining so i wanted to make something that has connection to the weather while being fun. This device directly shows the weather results in its oled screen without any trouble of phones. maybe in the future ill make an app that will notify the weather who knows.
Please note: majority of the parts are from the websites of my country so its easier to get and cheaper for us!
You can download the project files to edit the project as you like, maybe adding a new display, more sensors etc. I hope you like this project of mine and everything is straightforward as in the project files so you should be good on your own.

Questions
How big is the Weatherstationbyme PCB?
It measures 49.3 × 50 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Weatherstationbyme use?
8 parts, built around the ATMEGA328P-PU and DHT22. 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 Weatherstationbyme KiCad files?
From the iEarthEZ/Atmega328p-microcontroller-based-weather-station repository on GitHub, at the commit this page was made from: the board is weatherstationbyme.kicad_pcb and its schematic weatherstationbyme.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Weatherstationbyme design in my own project?
Its repository states no licence, so its author keeps all rights: ask iEarthEZ before reusing the design.
