This project is being developed as part of a school-based technical initiative and focuses on creating a compact, energy-efficient weather station powered by the ESP32S3 microcontroller. The goal is to reliably measure indoor temperature and humidity while also displaying a multi-day weather forecast in a clear and accessible format.

A 4.2-inch e-paper display is used to ensure excellent readability with minimal power consumption. To drive the display, a custom-designed PCB was created featuring the ESP32S3 as the main processor. The board is designed to be mounted directly on the back of the display and connected using 2.54 mm jumper wires, resulting in a clean and compact layout.

The weather station includes a built-in BME280 sensor that provides accurate temperature, humidity, and air pressure readings. Power is supplied via a USB-C connector, which also allows for easy programming of the ESP32S3. Additionally, three user-buttons are integrated on the top side of the PCB, enabling users to switch between display pages or manually refresh the screen.

An onboard I²C interface offers the ability to expand the system with additional sensors, making this project ideal for DIY enthusiasts. It only requires the custom PCB, the display, and a few standard components. The firmware is fully customizable, allowing the weather station to be tailored to a wide range of applications and user needs.

A collaboration with PCBWay would be a great asset to bring this project to life. As a trusted manufacturer of high-quality PCBs, PCBWay offers reliable fabrication, precise assembly, fast delivery times, and competitive pricing. Partnering with PCBWay would help accelerate the development process and make the project more accessible to a broader community of makers and students.
