⚙️Properties
When you want to override the default settings, you can adjust some of the module's default parameters.
Measurement properties
sampleTime
60
The duration of the measurement in seconds. Default is set to 1 minute. `
Note that the sampleTime must be at least 35 seconds to perform a correct analysis.
flashEnabled
true
When enabled and supported by the device the SDK will turn on the camera flashlight while measuring.
Note that an (external) light source is necessary to perform a good measurement.
gravEnabled
false
When enabled and supported by the device, gravitational data will be included in the measurement.
gyroEnabled
false
When enabled and supported by the device, gyroscope data will be included in the measurement.
accEnabled
false
When enabled and supported by the device, accelerometer data will be included in the measurement.
rotationEnabled
false
When enabled and supported by the device, rotational data will be included in the measurement.
movementDetectionEnabled
true
When enabled the onMovementDetected()
event will be thrown when movement is detected.
fingerDetectionExpiryTime
-1
The time until the finger detection will trigger the onFingerDetectionTimeExpired
() event.
By default this value is -1
, which indicates that it will keep waiting until a finger is detected.
pulseDetectionExpiryTime
10
The time until the pulse detection will trigger the onPulseDetectionTimeExpired
() event.
waitForStartRecordingSignal
false
By default the measurement will start automatically after calibration is ready. When this flag is enabled, the measurement will wait until the startRecording()
command has been given.
Take a look at the following platform-specific code snippets to see how to change the default measurement settings for each platform. It's only necessary to provide values for non-default properties. These values should only be changed in exceptional cases.
Platform-specific properties
Graph Settings
graphBackgroundColor
Determines the graphBackground color. By default there is no background color
drawGraph
When enabled the component draws a graph of the recorded PPG signal.
lineColor
Determines the color of the graph line.
lineThickness
Determines the thickness of the graph line.
drawBackground
When enabled, the component will draw a background for the graph
