Understanding Hall Effect Sensors
But they are also used in many distributorless ignition systems (DIS) to determine the position of the crankshaft and camshaft. This is because the engine computer needs to know where the number one cylinder is as soon as the engine is cranked. As soon as the all-important "sync-pulse" is detected, the ignition module can start firing the plugs in the correct sequence. This also allows injector timing to be matched to the firing order in engines with sequential fuel injection. Hall Effect Sensors are sometimes referred to as "switches" rather than sensors because of the on-off "digital" voltage signal they produce. Unlike magnetic sensors that produce an alternating current (AC) signal which varies in voltage with speed, Hall Effect Sensors produce a constant voltage signal that can change abruptly from maximum voltage to nearly zero and back again regardless of engine speed. This produces a square wave output signal that can be easily used by the onboard computer for timing purposes. INNER WORKINGS A typical Hall Effect Sensor has three wires or terminals: one for ground, one for supply or reference voltage and one for the output signal. To produce an output signal, a Hall Effect Sensor must be supplied with a reference voltage from the vehicles onboard computer (which may be 5 to 12 volts depending on the application). The supply voltage is necessary to create the switching effect that takes place inside the sensor.
