Sensor
Limited availability
This feature is not Baseline because it does not work in some of the most widely-used browsers.
Secure context: This feature is available only insecure contexts (HTTPS), in some or allsupporting browsers.
TheSensor interface of theSensor APIs is the base class for all the other sensor interfaces. This interface cannot be used directly. Instead it provides properties, event handlers, and methods accessed by interfaces that inherit from it.
This feature may be blocked by aPermissions Policy set on your server.
When initially created, theSensor object isidle, meaning it does not take measures. Once thestart() method is called, it prepares itself to read data and, once ready, theactivate event is sent and the sensor becomesactivated. It then sends areading event each time new data is available.
In case of an error, theerror event is sent, reading stops, and theSensor object becomesidle again. Thestart() method needs to be called again before it can read further data.
