![]() Measures the proximity of an object in cm relative to the view screen of aĭevice. Measures the ambient air pressure in hPa or mbar. Measures degrees of rotation that a device makes around all three physical axes (x, y, z).Īs of API level 3 you can obtain the inclination matrix and rotation matrix forĪ device by using the gravity sensor and the geomagnetic field sensor in conjunction with ![]() Measures the ambient geomagnetic field for all three physical axes (x, y, z) in Monitoring acceleration along a single axis. Measures the acceleration force in m/s 2 that isĪll three physical axes (x, y, and z), excluding the force of gravity. Measures the ambient light level (illumination) in lx. Measures a device's rate of rotation in rad/s around each of the three Measures the force of gravity in m/s 2 that is applied to a device on all Measures the ambient room temperature in degrees Celsius (☌). Measures the acceleration force in m/s 2 that is applied to a device onĪll three physical axes (x, y, and z), including the force of gravity. Sensor types supported by the Android platform. ForĮxample, a device can have two gravity sensors, each one having a different range. Also, a device can have more than one sensor of a given type. Tablets have an accelerometer and a magnetometer, but fewer devices haveīarometers or thermometers. Table 1 summarizes the sensors that are supported by the Androidįew Android-powered devices have every type of sensor. The linear acceleration sensor and the gravity sensor are examples of Software-based sensorsĭerive their data from one or more of the hardware-based sensors and are sometimes called virtual Sensors are not physical devices, although they mimic hardware-based sensors. Properties, such as acceleration, geomagnetic field strength, or angular change. They derive their data by directly measuring specific environmental Hardware-based sensors are physical components built Hardware-based and some are software-based. The Android sensor framework lets you access many types of sensors. It also provides an introduction to the sensor framework. This topic provides an overview of the sensors that are available on the Android platform.
