1# @ohos.deviceInfo (Device Information) 2 3The **deviceInfo** module provides terminal device information query, which cannot be configured by developers. 4 5> **NOTE** 6> 7> The initial APIs of this module are supported since API version 6. Newly added APIs will be marked with a superscript to indicate their earliest API version. 8> Some parameters whose return value is the default value are not yet available. 9> The APIs of this module return information about device constants. You are not expected to call these APIs frequently. 10 11## Modules to Import 12 13```ts 14import { deviceInfo } from '@kit.BasicServicesKit'; 15``` 16 17## Attributes 18> **NOTE** 19> Unless otherwise specified, the maximum data length is 96 bytes. 20 21**System capability**: SystemCapability.Startup.SystemInfo 22 23**Required permissions**: The items in the table below require different system capabilities. 24 25| Name| Type| Readable| Writable| Description| 26| -------- | -------- | -------- | -------- | -------- | 27| deviceType | string | Yes| No| Device type.
