WIFI Weather Station | Monitor and Send Local Weather Data to the Web - Platform for creating and sharing projects

This project uses the ATMEGA328P and consists of a great weather station for measuring temperature, humidity, wind, rain, and pressure. All data is communicated via wifi using an ESP-01s module and sent to a webserver.

These are the objectives that I had during the project:

To be able to live identify temperature and rain, even when not home;
To store historical data for developing a map of the microclimate of my home, and understand how the temperature and conditions inside it correlate to the weather outside;
To be able to automate further other home areas that need local weather information.
To learn more about hardware and software development.
To develop my first ATMega328P driver.

You can find the code implementation at:https://github.com/anardine/atmega328p-weather-station

The idea was also to do most of the project using through-hole components, since it's way easier to work with, and I did not have a size constraint. You can feel free to fork and adequate to a smaller version that would only have SMD components.

High Level Overview of the Aplication

This module works by fetching data in specific configurable timeframes (default to 1 minute) from all wather sensors and sending it to the Master (ATMEGA328-PU).

The master then sends this data to the ESP-01S to be able to post this to a server that collects the data for further usage.

The flash is to store data if the wifi reports failure on connection. The data is then fetched and sent when the wifi resumes working with the correct timeframe that the data was collected.
