1. Explanation of several angles Euler angle:http://baike.baidu.com/link?url= Vajuhz-luawv7zua-67dibb0jjwyyqqnwnqeejdrcomwdt1xrtjgq2anyojngfrkfoo3t_1gcwpebbgp3npfzq With Euler's angle, you can determine the following, roll angle, pitch angle, and yaw angle . In general, the right, front and top three directions of the carrier are formed right-hand system, the axis around the forward rotation is the roll angle , rotation around the right axis is the pitch angle , the axis around the upward

Acceleration Sensitivity AxisThe corresponding output voltage increases when accelerating along the sensitive axis Register Mappings Register Definition0x31-data_format Self_test bit: Set to 1, self-Test force applied to the sensor, resulting in output data conversion. A value of 0 o'clock disables self-test forceSPI bit: value 1, set device to 3-wire SPI mode, value 0, set to 4-wire SPI modeInt_invert bit: value 0, set interrupt to High active, value

The above has already introduced the porting process of android temperature sensor. The code page has been posted to everyone. Now we can write an APK for testing. The code is very simple, and the interface is very simple and ugly. Haha, don't mind. This aok is only used for testing. I will not introduce it more here and paste the Code directly.Package com. android. jay. sensor1;Import android. app. Activity;Import android. hardware.

After Android2.2, orientation sensors was deprecated.The official proposal is to use acceleration and magnetic sensor to calculateOn this question, csdn on a very good blog post.http://blog.csdn.net/flowingflying/article/details/43233315On stack Overflow:Http://stackoverflow.com/questions/10291322/what-is-the-alternative-to-android-orientation-sensorUse the words to see the code directly Packagecom.turtle920.androidaudioprocess;Importandroid.app.Activ

Each network has its own security rules. Similarly, wireless sensor networks also have their own security mechanisms. This article focuses on wireless sensor network security issues. I hope this article will help you. WirelessSensor Network Security Mechanism Security is a prerequisite for system availability. To ensure communication security, you must reduce system overhead and study feasible security algo

Motion sensors are useful for monitoring the movement of devices, such as tilt, vibration, rotation, and swing, which are the monitoring ranges of motion sensors. The movement of a device is usually a direct response to user input.All motion sensors return a value of three floating-point numbers, and for different sensors, the three values have different meanings. For example, for an accelerometer, the acceleration data for three axes is returned. For a gyroscope

Wireless sensor networks are emerging and have great potential for development. In the course of a new technological development, various related energy design, energy-saving solutions, optimization problems, and security issues need to be fully considered. This article briefly introduces the development process of wireless sensor network software and hardware. The Research on wireless

Wireless + sensor technology pushes IOT to the cloud Iot is a very big concept. It emphasizes that everything is connected to IOT and can communicate with each other wirelessly, its fields cover smart cities, smart medical care, smart industry, smart agriculture, and smart buildings. However, for various reasons, the construction of smart cities is still in its infancy, focusing on the development of intelligent transportation systems and power grid
