    Hi, I need help to build a circuit.
    I have a motor, and sensors.
    I want that the circuit to run by itself for long time, without anyone close to the area....
    I need that when the sensors will sense overload on the system the circuit will stop the motor from working, I thought to do it with SPST relay.
    I tried to do it with labview, but if the computer will have an error or shut down the motor will keep working without control, so this is not good for me...
    I prefer to just build a simple circuit but I don't know how...
    Please help, if someone can give me instructions how to build it I will be very greatfull,
    thanks in advance,
    Omer

    For the Labview approach, you could send commands to a control board every x seconds and if the code isn't received, stop the motor. Or, you could interface the sensor to a controller directly.

    How are you measuring overload? What does your sensor measure, and what form is the result?

    What voltage is the motor running at?

    What is the normal current, and what is the "Overload" current value?
