Enumeration properties
This article describes the static sensor properties that are available from the PnP Driver Store.
The following table shows static sensor properties. The Class Extension (CX) writes these properties for each sensor when SensorsCxSensorCreate is called. Client applications can use these properties to search for sensors on the Windows device.
For more information about the data types shown in the Type column, see PROPVARIANT structure.
| Property key | Type | Required/Optional | Description |
|---|---|---|---|
| DEVPKEY_Sensor_Type | VT_CLSID | Required | A GUID that identifies the type of sensor. For more information about sensor types, see Sensor type GUIDs. |
| DEVPKEY_Sensor_Category | VT_CLSID | Required | The sensor category. This key is for backwards compatibility with Desktop v1 stack, where it's a requirement. |
| DEVPKEY_Sensor_ConnectionType | VT_UI4 | Optional Required for Ambient Light Sensor and Accelerometer |
The sensor connection type. Sensor connection types can be integrated, attached, or external. For more information, see the SensorConnectionType enumeration. |
| DEVPKEY_Sensor_IsPrimary | VT_BOOL | Optional | An indication that this is the primary sensor. This key has a default value of false, if not set. |
| DEVPKEY_Sensor_Name | VT_LPWSTR | Required for custom sensors. | The name of the sensor. |
| DEVPKEY_Sensor_Manufacturer | VT_LPWSTR | Required | The manufacturer for the sensor. |
| DEVPKEY_Sensor_Model | VT_LPWSTR | Required | The model for the sensor. |
| DEVPKEY_Sensor_PersistentUniqueId | VT_CLSID | Required | A GUID that identifies the sensor. This value must be unique for each sensor of the same model on a device. This requirement applies to both internally and externally connected sensors. |
| DEVPKEY_Sensor_VendorDefinedSubType | VT_CLSID | Required for custom sensors. | A GUID that identifies a sensor category subtype that was defined by a vendor.For noncustom sensor, this key isn't required. |
| DEVPKEY_SensorData_LightLevel_AutoBrightnessPreferred | VT_BOOL | Optional | The light sensor is preferred for autobrightness. |
| DEVPKEY_SensorData_LightLevel_ColorCapable | VT_BOOL | Optional Required if supporting chromaticity and light temperature. |
The light sensor supports light temperature and/or chromaticity x/y. |
