AmbientLightSensor.AmbientLightSensor()

The AmbientLightSensor() constructor creates a new AmbientLightSensor object, which returns the current light level or illuminance of the ambient light around the hosting device.

If a feature policy blocks use of a feature it is because your code is inconsistent with the policies set on your server. This is not something that would ever be shown to a user. See Feature-Policy for implementation instructions.

var ambientLightSensor = new AmbientLightSensor(options)

options Optional

Currently only one option is supported:

• frequency: The desired number of times per second a sample should be taken, meaning the number of times per second that sensor.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 device hardware and consequently may be less than requested.
