AmbientLightSensor: AmbientLightSensor() constructor - Web APIs | MDN
AmbientLightSensor: AmbientLightSensor() constructor Limited availability
The AmbientLightSensor()
constructor creates a new AmbientLightSensor
object, which returns the current light level or illuminance of the ambient light around the hosting device.
new AmbientLightSensor()
new AmbientLightSensor(options)
options
Optional
Currently only one option is supported:
frequency
Optional
The desired number of times per second a sample should be taken, meaning the number of times per second that reading
event 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 the device hardware and consequently may be less than requested.
