The ESP32 microcontroller, with its built-in, low-cost Hall sensor, offers many opportunities for interdisciplinary, practice-oriented physics teaching. In this article we present a fully functional anemometer that was designed using CAD software, manufactured via 3D printing, and calibrated using the ESP32’s integrated Hall sensor’s magnetic detection capabilities. A neodymium magnet embedded in the rotating roof passes near the Hall sensor, enabling the microcontroller to detect each rotation. A custom Python script then converted this rotation rate into the wind speed, enabling real-time measurement. This low-cost and student-friendly device is ideal for outdoor use on school rooftops or in gardens, and can be easily integrated into broader weather monitoring systems. This project situates physics learning in an authentic weather context and demonstrates how digital tools can enhance engagement and relevance in the classroom.
