    on my current project im trying to monitor two motors using transducers what im trying to achieve is this, if the motor fails i loose a 0v to my ic. alarm sounds.

    data sheet of tranducer.

    the way im trying to so it is this, set the motor to its lowest speed setting then use a trimming pot to adjust when the transistor turns on at the lowest speed setting, then if the motor fails and goes below the pre-set level i loose my 0v to my ic.

    just wondering if this is going to be a very accurate way to achieve this or is there another more accurate way i could do this, (id really struggle to program this obviously this would be the best way)

    thank you
