【實用生產應用app】Elevator Speed|最夯免費app

This will measure the speed and distance of an elevator using your devices accelerometer

Place the device against the elevator wall on a flat surface (e.g. the floor), follow the on screen instructions.

Don't worry if you don't hold it exactly straight, it will allow for that, but the device must be held VERY still and must not be moved after calibration, or the speed shown will be incorrect.
