# Features Source: [https://docs.qualcomm.com/doc/80-70015-7/topic/supported_features.html](https://docs.qualcomm.com/doc/80-70015-7/topic/supported_features.html) The following table lists the QSH features and their impact on the QSH for deployment in scenarios with IoT devices: Table : QSH features | Feature | Enable or disable? | Impact | Description | | --- | --- | --- | --- | | OS and hardware-independent | This feature is for information purposes only. |

Development is easy.

Plug and play of QSH-compliant sensors across the targets.

QSH drivers or algorithms are compliant across Qualcomm® Snapdragon
platforms.

APIs are generic, and abstract the underlying OS.

| | Sensors in local memory | This feature can be enabled or disabled. |

Saves power by enabling the local memory.

Due to the limited local memory, only finite sensors can be fitted in
here.

Enables QSH to operate in ultralow power mode, meeting the low-power
requirements of the industry.

Suitable for background use cases.

| | Sensors in Normal mode | Sensors can be configured to use either local or main memory. |

More memory and more on-chip resources are available.

Higher power consumption due to more on-chip resources being active.

Access to the larger main memory allows integration of more sensors.

Supports cycle-intensive operations.

QSH supports calibration for hardware-based sensors.

Calibration standardizes equipment for precise results, which ensures that the
sensor values match the baseline.

Recalibration maintains sensor accuracy and adjusts for sensitivity changes
over time.

For more information, see Calibrate.

| | Software-based sensors | These features can be enabled or disabled. | Includes device motion, activity, and device physical position sensors. |

These sensors are a set of software algorithms.

Enables device motion using significant motion.

Supports device positioning and direction using linear acceleration, gravity,
geomagnetic rotation vector, and rotation vector.

Step counter, step detector, and activity recognition help identify user
activities.
