ESP32 DIY Desktop Weather Station

Want to keep an eye on the weather without constantly checking your phone? 

This DIY Desktop Weather Station has you covered! It features an ESP32-S3 board that connects to Wi-Fi and fetches real-time weather updates, like temperature, humidity, and current conditions, directly from the OpenWeatherMap API. For indoor readings, it includes a built-in HPP845E031R4 sensor that monitors your room's temperature and humidity. Its E-Ink display consumes very little power and can operate for days on a single charge. After each weather update, it automatically enters sleep mode to conserve even more energy.

Components Required

• ESP32-S3-WROOM-1-N16R8
• 4.2" EPD (E-Ink) Display
• HPP845E031R4 Temperature & Humidity Sensor
• ADP124ACPZ 3.3V LDO Regulator
• MAX1898 Battery Charger IC

Desktop Weather Station Schematic Diagram

The weather station uses a custom-designed multi-color PCB that keeps the build neat, compact, and professional-looking. The PCB was designed using KiCad, and its dimensions are approximately 105mm × 90mm, making it perfect for desktop use. The design not only simplifies assembly but also adds a polished finish to the final product.

Assembling the Desktop Weather Station

Once the components are soldered and the board is assembled, simply power up the device and place it on your desk. The ESP32-S3 will handle all the background tasks, connecting to Wi-Fi, retrieving weather data, displaying it clearly on the E-Ink screen, and then entering sleep mode to save power.

It’s a compact, energy-efficient, and functional weather station that updates you with real-time information both indoors and outdoors. Whether you're building it for fun, education, or smart home integration, it’s a rewarding and practical DIY project.

The ESP32-S3-based Desktop Weather Station is a sleek and low-power solution for real-time weather updates. It combines wireless connectivity, local sensing, and an E-Ink display for a complete smart desktop gadget. With its clean PCB design and minimal component list, it’s perfect for electronics enthusiasts and makers. Whether for personal use or a tech-savvy gift, this project is both useful and fun to build.
