GravitySensor.GravitySensor()
The GravitySensor
constructor creates a new GravitySensor
object which
provides on each reading the gravity applied to the device along all three axes.
Syntax
let gravitySensor = new GravitySensor([options])
Parameters
- options Optional
- Options are as follows:
frequency
: The desired number of times per second a sample should be taken, meaning the number of times per second thatsensor.onreading
will be called. A whole number or decimal may be used, the latter for frequencies less than a second. The actual reading frequency depends on device hardware and consequently may be less than requested. The default frequency is the one defined by the underlying platform.referenceFrame
: The local coordinate system representing the reference frame. It can be either'device'
or'screen'
. The default is'device'
.
