sensorinternal

Sensorinternal is a designation used in some hardware and firmware documentation to refer to the subset of sensors that are built into a device and are not exposed as external peripherals. It may appear in system manifests, driver code, or firmware interfaces to distinguish these sensors from external or user-accessible ones. The term is not a standardized specification and its exact meaning can vary by vendor or project.

Typical sensorinternal components include temperature sensors on CPUs or SoCs, voltage and current sensors for power management, and onboard environmental or storage sensors. These sensors are often integrated on the same hardware package as processing elements and may share interfaces with external sensors but are sometimes subject to stricter access controls, calibration data, and firmware-managed compensation.

Access to sensorinternal data is usually mediated by a sensor framework, driver, or daemon in the operating system. Data is read through API calls or standardized interfaces, with timestamps, units, and calibration offsets applied in software or firmware. Sensorinternal information supports thermal management, power budgeting, system health monitoring, and autonomous control loops in embedded and consumer devices.

Security and privacy considerations include restricting access to sensitive internal state and preventing leakage of device status through sensor data. Calibration, drift, and noise must be managed, and firmware updates can modify sensor behavior or data interpretation.
