magnetometer sensor for android

the Rotated Vector is non-unit. The definition of the X, Y, and Z axes is the same as that of the accelerometer. The reference coordinate system is defined by direct orthogonal basis (1) Figure 1. coordinate system used by the rotating vector sensor This coordinate system has the following features: 1. the X axis is defined by the vector product yxz. It is tangent to the ground at the current position of the device and points to the east; 2. the Y a

This article translated from: http://developer.android.com/guide/topics/sensors/sensors_motion.html The Android platform provides several sensors that can monitor the movement of devices. Two of them are hardware-based (accelerometer and gyroscope). Three sensors can be hardware-based, it can also be software-based (Gravity Sensors, linear acceleration sensors, and rotating vector sensors ). For example, some software

The android accelerometer is of the sensor. type_accelerometer type. Return the value of the accelerometer through Android. Hardware. sensorevent. The Unit returned by the accelerometer is the unit of acceleration m/s ^ 2 (meter per second). The values in three directions are Values [0]: X-axis Acceleration Values [1]: acceleration in Y-axis direction Values [

interface. This interface can monitor various events on the sensor. The Sensoreventlistener interface code is as follows: Copy Code code as follows: Public interface Sensoreventlistener { public void Onsensorchanged (Sensorevent event) { } public void onaccuracychanged (Sensor Sensor, int accuracy) { } }

This article describes how to obtain a list of sensors supported by your Android device.Currently, Android 4.4 (API level 19) supports the following sensors:Type_accelerometer Accelerometer, Unit m/s2, measurement of the accelerometer type values (sensors type) applied to the device x, Y, Z axes: 1 (0x00000001) Type_ambient_ Temperature temperature sensor, Unit i

Sensor overviewSensors are one of the important symbols of the second generation of smartphones. Many phones and tablets are now built-in with sensors (except TV). The Android SDK supports a number of more than 10 sensors, but the phone only supports a subset. such as the direction sensor (electronic compass) and the gravity
