SENSOR: HALL or PWM
Wiring for three wires (1 output) Hall sensor. If sensor has no internal source driver or has low
side (open collector) output with no internal pull up resistor, connect any small 4.7Kohm –
10Kohm resistor between its output and positive power lead. You can connect it directly
between terminal ports 2 - 3.
