I'm having no luck getting anything out of this current sensor. I've hooked it up to something drawing about 5 Amps, powered the sensor with 5v and placed the necessary capacitors across the pins. The Vout should be higher than Vref when current is flowing but they are both about 2.5v whether current flowing or not. Also tried putting a lower voltage into Vref, about 2v, which just lowered the Vout voltage to the same and made no difference when drawing current.
Here is the info for the device...

Has anyone had experience with these devices or know of another way to sense current? I don't need accurate measurement, just need to know if something is running or not (woodworking machinery like tablesaw, etc...)
