A DIY weather station project is presented that utilizes a Raspberry Pi, PHP, Python, and an Arduino board. The project's goal is to build a low-cost, home-based weather monitoring system that can track temperature and humidity levels throughout the house. The project involves several steps, including setting up the hardware components, installing necessary software packages, creating a web application using PHP and Twig templating engine, and configuring NGINX for serving the application. The final result is a functional weather station that can be accessed from any device on the home network.
