| + | Sensor attributes | ||
| + | |||
| + | Location <CLLocation> | ||
| + | |||
| + | altitude: for getting the height, just like the altitude in geography. Measured by meter | ||
| + | coordinate(latitude, longitude): just same as those in geography. | ||
| + | For latitude, the range should be [-90(south pole), 90(north pole)]. | ||
| + | For longitude, the range should be [-180(west of the prime meridian), 180(east of the prime meridian)] | ||
| + | |||
| + | course: | ||
| + | Course values are measured in degrees starting at due north and continuing clockwise around the compass. Thus, north is 0 degrees, east is 90 degrees, south is 180 degrees, and so on. Course values may not be available on all devices. A negative value indicates that the direction is invalid. | ||
| + | |||
| + | |||
| + | horizontalAccuracy | ||
| + | The radius of uncertainty for the location, measured in meters. | ||
| + | The location’s latitude and longitude identify the center of the circle, and this value indicates the radius of that circle. A negative value indicates that the location’s latitude and longitude are invalid. | ||
| + | |||
| + | |||
| + | speed:The instantaneous speed of the device in meters per second. | ||
| + | |||
| + | time:The time at which this location was determined. | ||
| + | |||
| + | verticalAccuracy:The accuracy of the altitude value in meters. The value in the altitude property could be plus or minus the value indicated by this property. A negative value indicates that the altitude value is invalid. | ||
| + | |||
| + | |||
| + | Accelerometer <UIAccelerometer> | ||
| + | |||
| + | x, y, z: the accelerometer for the device in triple direction | ||
| + | |||
| + | timestamp:The relative time at which the acceleration event occurred. | ||
