![]() Methods that let you determine a sensor's capabilities. Sensor You can use this class to create an instance of a specific sensor. That are used to report sensor accuracy, set data acquisition rates, and calibrate sensors. This class also provides several sensor constants Listeners, and acquiring orientation information. Various methods for accessing and listing sensors, registering and unregistering sensor event The sensor framework is part of the android.hardware package and includes the followingĬlasses and interfaces: SensorManager You can use this class to create an instance of the sensor service. You can access these sensors and acquire raw sensor data by using the Android sensor framework. This sensor was replaced with the TYPE_AMBIENT_TEMPERATURE sensor in Measures the temperature of the device in degrees Celsius (☌). Measures the orientation of a device by providing the three elements of the device's Monitoring dewpoint, absolute, and relative humidity. Measures the relative ambient humidity in percent (%). This sensor is typically used to determine whether a handset is being held up to 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. ![]() Register and unregister sensor event listeners that monitor sensor changes.Acquire raw sensor data and define the minimum rate at which you acquire sensor data.Determine an individual sensor's capabilities, such as its maximum range, manufacturer, power.Determine which sensors are available on a device.For example, you can use the sensor framework to do the following: The sensor framework provides several classes and interfaces that help you perform a wide You can access sensors available on the device and acquire raw sensor data by using the Android These sensors measure the physical position of a device. This category includes barometers, photometers, and These sensors measure various environmental parameters, such as ambient air temperatureĪnd pressure, illumination, and humidity. ThisĬategory includes accelerometers, gravity sensors, gyroscopes, and rotational vector These sensors measure acceleration forces and rotational forces along three axes. The Android platform supports three broad categories of sensors: Refer to the following related resources: Migrate to Google Play services location and context APIs.
