Sensor introduction: Speaking of sensors, I believe everyone will be familiar with it. For example, an acceleration sensor is used for shaking;Sensor DefinitionA physical device or biological organ that can detect and feel external signals and physical conditions (such as light, heat,Moderate) or chemical

light intensity into different levels. The maximum value of each level is represented by a constant. These constants are defined in the sensormanager class. The Code is as follows: Public static final float light_sunlight_max = 120000.0f; Public static final float light_sunlight = 111080000f; Public static final float light_shade = 20000.0f; Public static final float light_overcast = writable F; Public static final float light_sunrise = 400366f; Public static final float light_cloudy = 1

change.It should be noted that although there are 9 elements of the rotation matrix, but only 3 degrees of freedom, so not any matrix can be used as the rotation matrix, the rotation matrix needs to be orthogonal matrix (that is, inverse matrix equals transpose matrix).In addition, another name for the rotation matrix is called the direction cosine matrix (Direction cosine matrix), or DCM, which is more commonly used in the field of gyroscope mechani

Using the MPU6050 hardware DMP to solve the attitude is very simple, the following describes the three-axis gyroscope and the value of the accelerometer to use the four-number software to solve the attitude of the method.Let's take a look at how to describe a plane rotation (coordinate transformation) with Euler's angle:A coordinate system is arranged around the rotation of the α angle to obtain a coordinate system, in space there is a vector in the c

Applications: Acceleration sensing, force size and direction sensing. (In many computers there is also a built-in accelerometer, the basic application scenario is to protect the hard drive when the computer falls) Representative Example: kissingly class application, Bowling game (Super Ball Escape), Fishing games Three-axis gyroscope Principle: A single axis can only measure the amount of One direction, that is, a system requires three

The following are several constants defined in the API that represent sensor. Int Type_accelerometer A constant describing an accelerometer sensor type. Acceleration Sensor Int Type_all A constant describing all sensor types. All Types A constant describing all sensor types. Int Type_gravity A constant describing a gravity sensor type. Int Type_gyroscope A constant describing a gyroscope sensor type rotary instrument sensor Int Typ

!" You can skip this step and continue using the gyroscope. we will try to find the minimum and maximum output values for the Earth's magnetic field on each axis. This basically works like calibrating an accelerometer, except that the Earth's magnetic field does not drop straight. Depending on where you are on the planet, it points at a certain angle to the northern hemisphere (southern hemisphere) or the northern Hemisphere (northern hemispher

-compromise MEMS sensor.6) Acceleration SensorCommonly known as acceleration regulation, g-sensor, can sense the acceleration of the object. In fact, the accelerometer is implemented in many ways, MEMS is only one of the methods, the use of MEMS accelerometer sensor is indeed the current trend.Acceleration sensor generally has "x, y two axes" and "x, Y, z three axes" two, two axes more for vehicles, ships and other plane movement for more, three axes more for missiles, aircraft and other flying

The built-in accelerator is one of the coolest features of a smartphone. ios can use this small device to know how the user holds the mobile phone and whether the user has moved the mobile phone. ios uses the accelerator to process automatic rotation, in addition, many games use it as a control mechanism. It can also be used to detect shaking and other sudden movements. This feature has been further expanded since iPhone 4 and includes a built-in gyroscope
