Sensor: error event

The error event is fired when an exception occurs on a sensor.

The Sensor interface is a base class, onerror and the error event may only be used on one of the derived classes.

After this event has occurred, the Sensor object becomes idle. If the sensor was reading values, it will stop until it restarts.

Syntax

Use the event name in methods like addEventListener(), or set an event handler property.

addEventListener('error', event => { })

onerror = event => { }
