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

The diagram is as follows: From the diagram above, we can see that in Android, sensor is divided into four layers: Driver layer (sensor driver), Hardware Abstraction Layer (native), middle layer (framework), and application layer (Java ). The hardware abstraction layer and the intermediate layer can be combi

Model Design reason: GPS provides global, around-the-clock, and real-time navigation Advantages. However, when satellite signals such as high-rise buildings, Boulevard, overpasses, and culvert tunnels are "blind spots, GPS cannot provide users with precise navigation information, especially continuous navigation information. Dr (dead-reckoning) uses a direction sensor (Gyroscope) and a speed sensor (mileage meter) to estimate the instantaneous locatio
