AWARE: Significant Motion
This sensor is used to track device significant motion. Also used internally by AWARE if available to save battery when the device is still with high-frequency sensors. SignificantMotionSensor.Observer allows programmers to take actions on detection of a significant motion.
Based of: sensorplatforms/open-sensor-platform/significantmotiondetector.c
Requirements
iOS 10 or later
Installation
com.awareframework.ios.sensor.significantmotion is available through CocoaPods.
- To install it, simply add the following line to your Podfile:
pod 'com.awareframework.ios.sensor.significantmotion'
- Import com.awareframework.ios.sensor.barometer library into your source code.
import com_awareframework_ios_sensor_significantmotion

Broadcasts
Fired Broadcasts
SignificantMotionSensor.ACTION_AWARE_SIGNIFICANT_MOTION_STARTED
fired when there is a significant motion.SignificantMotionSensor.ACTION_AWARE_SIGNIFICANT_MOTION_ENDED
fired when the significant motion has ended.
Received Broadcasts
SignificantMotionSensor.ACTION_AWARE_SIGNIFICANT_MOTION_START
: received broadcast to start the sensor.SignificantMotionSensor.ACTION_AWARE_SIGNIFICANT_MOTION_STOP

Data Representations
SignificantMotion Data
Contains the motion changes.
Field | Type | Description |
---|---|---|
moving | Boolean | Indicates that a significant motion was detected or not. |
label | String | Customizable label. Useful for data calibration or traceability |
deviceId | String | AWARE device UUID |
label | String | Customizable label. Useful for data calibration or traceability |
timestamp | Long | unixtime milliseconds since 1970 |
timezone | Int | Ttimezone of the device |
os | String | Operating system of the device (ex. android) |
Example usage
let sensor = SignificantMotionSensor.init(SignificantMotionSensor.Config().apply{config in
config.sensorObserver = Observer()
config.debug = true
config.dbType = .REALM
})
sensor.start()
sensor.stop()
}
class Observer:SignificantMotionObserver{
func onSignificantMotionStart() {
// Your code here...
}
func onSignificantMotionEnd() {
// Your code here...
}
}
