Qt Sensors

The Qt Sensors module provides access to sensor hardware via QML and C++ interfaces.

Currently, the API is supported on Android, iOS, and Windows (MSVC).

Using the Module

QML API

The QML types of the module are available through the QtSensors import. To use the types, add the following import statement to your .qml file:

import QtSensors

C++ API

Using a Qt module requires linking against the module library, either directly or through other dependencies. Several build tools have dedicated support for this, including CMake and qmake.

Building with CMake

Use the find_package() command to locate the needed module component in the Qt6 package:

find_package(Qt6 REQUIRED COMPONENTS Sensors)
target_link_libraries(mytarget PRIVATE Qt6::Sensors)

For more details, see the Build with CMake overview.

Building with qmake

To configure the module for building with qmake, add the module as a value of the QT variable in the project's .pro file:

QT += sensors
