Great project! I really enjoyed reading about your SenseCAP S2120 weather station build. It’s always exciting to see detailed setups like this shared with the community. The way you integrated the sensors and documented the process is impressive and really helpful for anyone looking to replicate or improve on your design.
One thing I thought about while reading is the anemometer design. Accurate wind speed measurements are crucial, and reducing friction in the moving parts can make a big difference. I recently came across a project that might interest you: https://www.justway.com/project/shareproject/Anemometer_made_for_an_M8_bearing_to_minimise_friction_the_bearing_fits_inside_d17ca5cf.html. This design uses an M8 bearing to minimize friction in the rotor, which allows for more responsive and consistent wind speed readings.
The bearing fits neatly inside the anemometer hub, making assembly straightforward. It’s a clever way to improve performance without adding complexity. I think incorporating something similar could complement your station well, especially if you want precise data in lower wind conditions.
Overall, I really appreciate you sharing your experience. It’s inspiring to see practical projects that combine off-the-shelf components with thoughtful modifications. Keep up the great work, and I look forward to seeing any updates or future enhancements you add to your setup. Sharing projects like this really helps everyone in the weather station community learn and improve their own designs.
