Does anyone have any thoughts on the easiest way to detect whether or not an AC motor is running?
I would like to end up with a 5 v max. signal, and all I am interested in is whether or not it is running.
The main objective is the ease of installation, as I would like to be able to just "stick" it on the motor itself without getting into the wiring.
Do you suppose there would be any kind of magnetic field sufficient to operate a magnetic reed switch or hall effect sensor or something of that nature?
