# Radiosonde Hardware

This hardware serves as a single place to find information on the hardware used by contemporary production radiosonde models.

The original Vaisala RS41 repo has been moved to /Vaisala_RS41.

There is still a lot of stuff missing (especially parts lists, technical descriptions and theory of operation), any help is encouraged!

High-Resolution versions of the scans are provided at https://drive.google.com/drive/folders/1vTpQza6widsPxRtqeBz5mPLFOcSugiRx

Other radiosonde models might be added is they fulfil the requirements for relevance and asset quality (photos vs. scans etc.).
