Weather Station with Distributed Sensors

This weather station project offers a unique twist on a common endeavor. Built using the ESP32 platform, it stands out with its modular and wireless design, enabling easy scalability. The project showcases both a base station and sensor modules, all benefiting from the ESP32’s wireless capabilities and energy-efficient operation. Notable innovations include carbon dioxide, volatile organic compound, and nitrogen oxide sensors in the base station, as well as a screen displaying local and forecast data fetched from the OpenWeatherMap API. Why not make this project even more comfy by using the ESP32 WiFi Bluetooth Dual ESP-32 ESP-32S ESP8266 OLED Module and if you’re leaning more towards a Raspberry Pi route then check out how our article on weather stations and Raspberry Pi Picos.

Each module incorporates BME280 sensors for temperature, pressure, and humidity. Solar panels and batteries are integrated into each module to power the ESP32 chips efficiently. The integration of ESP-NOW technology enables seamless communication between the modules without requiring a central router. The project also delves into programming the base station’s graphical user interface, making it an informative guide for those interested in building their own weather station, with an added bonus of sending data to services like Weather Underground.
