AmbientLightSensor() constructor creates a new

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.onreadingwill 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.
