# Develop sensors

This section covers the development and integration process for sensor drivers and algorithms within the Qualcomm® sensing hub (QSH) framework. Before starting, read [Messages](https://docs.qualcomm.com/doc/80-80022-7/topic/data_model.html#data-model) to understand the `.proto` file schemas and message model.

- [Sensor and sensor instances](https://docs.qualcomm.com/doc/80-80022-7/topic/sensor_and_sensor_instances.html#sensor-and-sensor-instances) — Sensor and sensor instance lifecycle, producer/consumer model, and shared instance behavior.
- QSH services — Stream service, attribute service, diagnostic service, GPIO service, and other framework services available to drivers.
- [Calibrate sensors](https://docs.qualcomm.com/doc/80-80022-7/topic/calibrate.html#calibrate) — Factory and runtime calibration procedures required before production deployment.

## Develop and integrate sensor drivers

To develop and integrate custom sensor drivers, see
