The onreading EventHandler is called when a reading is taken on one of the child interfaces of the Sensor interface.


sensorInstance.onreading = function
sensorInstance.addEventListener('reading', function() { ... })

Because Sensor is a base class, onreading may only be used on one of its derived classes.
