I need to place 3 hall effect sensors outside and a considerable distance from the arduino.
you'll only have 5 Postive + , Negative - , and 3 signal wires. At the sensors have the power leads paralleled, and then you will only have the 3 individual signal wires coming back. easy So a cat5 (8 wire) will be more than enough
