Getting started with the Ambient Light Sensor
Dean Hume’s been doing a lot great work with PWA’s recently, and he’s also been exploring a lot of the new platform API’s, in this case the Generic Sensor API: The Ambient Light Sensor API provides developers with the means to determine ambient light levels as detected by the device’s main light detector. This information is available to developers in terms of lux units. If you are building a Progressive Web App and you want to style it differently depending on the light levels in the room, then this could be the feature for you.
