I need an innovative suggestion!
Im trying to design a device which uses a motor and has a safety cut out feature.
Basically I will have a motor running and i need a remote device to cut the power to the motor when the device gets within a certain range of the motor.
Ideally the remote device will not need a power source. I was thinking that some sort of emmiter (of radio signals or something) would be connected to a circuit controlling the motor which constanly pumps out a short range signal. When this remote device gets within a meter for instance of the motor , the signal is bounces back to the circuit and power is cut to the motor via some sort of relay switch.
I hope ive explained what Im trying to do - i apologise if it sounds confusing.
Does anyone have any idea of a device which can do this?
