Source: Basic working principle of magnetometerThis article is so good that I can't help but turn around.This article explains in detail the basic working principle of magnetometer, the cause of interference and how to calibrate, how to use the magnetometer and inclination sensor.Original address: http://www.dzsc.com/data/html/2010-11-29/87454.html The electronic compass is an important navigation tool which can provide the moving object's heading and posture in real time. With the progress of s

of the four-rotor aircraft, and the position control is based on the perfect attitude control. As already mentioned, it is unreliable to obtain the angle value only by gyroscope integral, because of the inherent drift of the gyroscope, the error caused by the integral becomes more and more large, and the accelerometer is susceptible to noise and vibration disturbance. Therefore, the two kinds of data are fused using various algorithms to obtain the i

acceleration sensor data will be changed, the answer is yes, the mobile phone acceleration sensor data will have a brief but significant changes, why, the mobile phone force balance acceleration of 0 because it is a whole, But the internal components will be affected by the complex force between the left and right, not the force at the same time to achieve the force balance, in fact, change the train of thought. With a similar interior smooth container, the container contains a few glass balls,

The accelerometer demonstrates the use of windows. devices. sensors. The API of the accelerometer. This simple allows users to browse the accelerated army along X-, Y-, and a 3-axis Z-axes accelerometer. You can choose one of the three scenarios: • Events of accelerometer data • Events of

Accelerometer Electronic Compass Gyroscope Proximity sensor Function The human body motion is determined by measuring the acceleration of the three axes. Determine orientation by measuring the intensity and direction of th

The gravity sensor provided by Windows Phone xNa allows users to determine the direction of mobile phone movement based on the principle of gravity measurement, allowing users to control game execution by shaking or shaking mobile phones, it works in the same way as the airbag of an automobile. It is immediately inflated when a vehicle is quickly slowed down to protect drivers and passengers from injury. Use Gravity Sensors as a gameProgramXNa-based game programs can use the features provided by

Let's look at these 11 sensors in turn.1 Acceleration SensorThe accelerometer is also called G-sensor, which returns The acceleration values for the X, Y, andz axes. This value contains the effect of gravity, in units of m/s^2. Put your phone flat on the desktop,x -axis defaults to 0,y - axis default 0,z Axis default 9.81. Place your phone face down on the desktop with az axis of -9.81. Tilt the phone to the left and thex -axis as positive. Tilt the

The XDK works with Web applications and local Web servers that operate in Java applications.Once you have the XDK installed, you can launch the app by clicking on the XDK icon in the Chrome browser. Note that the Appmobi XDK does not replace the Web development tools you choose, but rather provides a separate platform for building, testing, and deploying Web pages or hybrid applications, while still using the optional Integrated development environment (I

designed to measure the rotating motion of a device. Better at the movements of devices. However, the location of the device cannot be determined.The advantage of a accelerometer is to measure the force of a device. Better at the movement of devices than external reference objects (such as the ground. However, it is not accurate to measure the placement posture of the device relative to the ground.The strength of a magnetic meter lies in positioning

The following are all converted from the android game programming entry-level classic. For more information, see the source. An interesting input method in the game is the accelerator. All Android devices require a 3D accelerator. Also, the compass function can sense the magnetic field direction and the mobile phone pitch angle. To obtain the accelerometer information, we register a listener. The interface to be implemented is sensoreventlistener, whi
