# Develop with sensor APIs

For driver and algorithm authors on the low-power processor. The Qualcomm® sensing hub (QSH) sensor APIs provide the framework for implementing physical sensor drivers and virtual sensor algorithms on the application digital signal processor (aDSP). Before writing code, read [Data Model](./sensor_api_messages) to understand the `.proto` file schemas and message model.
