The engineer shows you how the phone's accelerometer works, with video-assisted instructions

BIN CHEN May 23, 2012, Evening 10:34 12 Some mobile phone players and enthusiasts are interested in the components of some mobile phones and even want to know how they work. Now, both mobile phones and tablets are basically built-in acceleration sensors to identify the direction of the device's rotation. Bill Hammack, an engineer from Illinois University, briefed us on how this acceleration sensor works and is not a tedious sermon, but an animated film to help explain it.Bill Hammack used Andr

Cocos2d-x accelerometer instance: moving ball, cocos2d-x Acceleration

Cocos2d-x accelerometer instance: moving ball, cocos2d-x AccelerationNext we will use an example to describe how to access the accelerometer through layer-based accelerometer events. As shown in this example, there is a ball in the scene. When we place the mobile device horizontally, the screen is up, and then shake the mobile device left and right to change the

Principle of MEMS accelerometer for inertial navigation

One accelerometer principleThe 1.1 accelerometer consists of a MEMS sensor and a signal processing chip.1.2 MEMS Accelerometer Working principleIt is composed of upper capacitance, medium capacitance plate (movable), lower capacitance plate, etc., when the acceleration reaches a certain value, the medium capacitance plate will move, and the distance from the uppe

Onenet Kylin seat Application development: acquisition of accelerometer ADXL345 data

Because the data acquisition station is basically installed in the field or the roof, the installation location and vibration have certain influence on the accuracy of the test data. So want to have a position state data, just found Kylin made on the ADXL345, such a digital output acceleration sensor. As shown in the red box:1 , ADXL345 OverviewADXL345 is a 3-axis, digital output accelerometer based on Imems technology from Adi. The characteristics of

Use of the Android accelerometer: shake-shake function implementation

First, the principle of introduction:The function of shaking in Android phone is already very common, recently contacted this function, the principle is very simple: using accelerometer, when shaking the phone, listen to the acceleration in all directions of change, when the acceleration value exceeds the set sensitivity, then trigger shake function.Second, the use of the class:SensormanagerSensoreventlistenerThird, the function realization:1, shake a

Android: Accelerometer

Android: Accelerometer Welcome to the sensor world.The sensor literally refers to the instrument that transmits the feeling. What is the feeling?Visual, auditory, taste, touch, and smell.Some people say that the existence and development of sensors allow objects to have the senses such as touch, taste, and smell, so that objects can gradually become active.At present, Android devices have been integrated into dozens of sensors, and we usually have acc

Acceleration Sensor Accelerometer

Acceleration Sensor Accelerometer The Android system supports powerful management services for sensors. The steps for developing sensor applications are as follows: (1) Call the getSystemService (Context. SENSOR_SERVICE) method of Context to obtain the Sensor Manager object. The SensorManager object represents the system's Sensor management service. (2) Call the getdefasensensor (int type) method of SensorManager to obtain the sensor of the specified

Android Accelerometer Magical and custom view

The example in this section is a tilt angle measurement application that accurately measures the tilt angle of your phone and the horizontal plane, using the acceleration sensor inside the Android sensor. The physical meaning represented by the various values of the accelerometer, coupled with a very simple algorithm, can be used to measure the tilt angle.The angle value is displayed exactly as the phone tilts and the effectNot much nonsense to say di
