    Is there a away that i can start a motor at a reasonable speed using only a pir sesnor? I want my circut to be as small as possible and no, an arduino nano or mini wont do it.
    Even if you have a suggestion that will make tbat circut bigger i want to hear it, just no arduino (tbh its a little complicated)

    Hi Jack. Try looking for a PIR activated relay circuit. The relay will act as a switch to turn on and off power to your motor (depending on how you are driving the motor), however we don't know what motor, or what is a reasonable speed, or the function of the motor. Hope that helps. Others can help you further who know a hell of a lot more than me. :)
