DeviceProximityEvent

distance of a nearby physical object using the proximity sensor of a device

We'll use max, min (max-min sensing distance the sensor is able to report, in centimeters) and value for the current proximity, in centimeters.

		
window.addEventListener('deviceproximity', function(event) {
    const min = event.min;
    const max = event.max;
    const value = event.value;
			...
});
