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. The
Feature-Policy HTTP header article contains implementation instructions.
new AmbientLightSensor() new AmbientLightSensor(options)
Currently only one option is supported:
The desired number of times per second a sample should be taken, meaning the number of times per second that
readingevent 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.
