Accelerometer

The device's current acceleration. Note that the z property includes Earth's gravitational acceleration.
The values below describe properties of the sensorVars.accelerometer.latestValue variable, and as such, the schema of the items in the sensorVars.accelerometer.values array.
Property
Values
Description
x
Negative or positive decimal, e.g. -6.71.
Acceleration along the X axis, as m/s².
y
Negative or positive decimal, e.g. 2.05.
Acceleration along the Y axis, as m/s².
z
Negative or positive decimal, e.g. 4.29.
Acceleration along the Z axis, as m/s².
timestamp
ISO 8601 format string, e.g. 2019-08-27T12:50:38.976Z.
Timestamp of when the value was recorded.

Barometer

The atmospheric pressure around the device.
The values below describe properties of the sensorVars.barometer.latestValue variable, and as such, the schema of the items in the sensorVars.barometer.values array.
Property
Values
Description
pressure
Positive decimal, e.g. 101.2.
Atmospheric pressure, in kilopascals.
timestamp
ISO 8601 format string, e.g. 2019-08-27T12:50:38.976Z.
Timestamp of when the value was recorded.

Compass

The device's current heading.
The values below describe properties of the sensorVars.compass.latestValue variable, and as such, the schema of the items in the sensorVars.compass.values array.
Property
Values
Description
heading
Positive decimal between 0…360, e.g. 64.71.
The direction in which the device is facing, given as degrees from true north. 0 degrees represents true north, and the direction is determined clockwise (which means that east is 90 degrees and west is 270 degrees).
timestamp
ISO 8601 format string, e.g. 2019-08-27T12:50:38.976Z.
Timestamp of when the value was recorded.

Geolocation

The device's current position, altitude, heading and speed.
The values below describe properties of the sensorVars.geolocation.latestValue variable, and as such, the schema of the items in the sensorVars.geolocation.values array.
Property
Values
Description
latitude
Negative or positive decimal, e.g. 60.1699.
Latitude of the device, in decimal degrees.
longitude
Negative or positive decimal, e.g. 24.9384.
Longitude of the device, in decimal degrees.
altitude
Negative or positive decimal, e.g. 4.29.
Altitude of the device, in meters, relative to sea level. If the device does not provide this information, this value will be null.
accuracy
Positive decimal, e.g. 1235.04.
Accuracy of the latitude and longitude parameters, in meters.
altitudeAccuracy
Positive decimal, e.g. 15.11.
Accuracy of the altitude parameter, in meters.
heading
Positive decimal between 0…360, e.g. 90.4.
The direction in which the device is traveling, given as degrees from true north. 0 degrees represents true north, and the direction is determined clockwise (which means that east is 90 degrees and west is 270 degrees).
speed
Positive decimal, e.g. 0.35.
Velocity of the device, in meters per second.
timestamp
ISO 8601 format string, e.g. 2019-08-27T12:50:38.976Z.
Timestamp of when the value was recorded.

Gyroscope

The device's current rotation.
The values below describe properties of the sensorVars.gyroscope.latestValue variable, and as such, the schema of the items in the sensorVars.gyroscope.values array.
Property
Values
Description
x
Negative or positive decimal, e.g. -6.71.
Angular velocity of the device along its X axis, in m/s².
y
Negative or positive decimal, e.g. 2.05.
Angular velocity of the device along its Y axis, in m/s².
z
Negative or positive decimal, e.g. 4.29.
Acceleration along the Z axis, as m/s².
timestamp
ISO 8601 format string, e.g. 2019-08-27T12:50:38.976Z.
Timestamp of when the value was recorded.
