Controlling the fan was seemingly straightforward. The voltage carries through the conductive plate and flows to the output lead. Note: Hall sensors work on the hall-effect principle that when a current-carrying conductor is exposed to the magnetic field, charge carriers experience a force based on the voltage developed across the two. The code shown above would only 'directly' work with a Reed relay, which is not to say that it won't work at all for a hall effect sensor, but that it would provide additional challenges using a hall-effect sensor. If you decide to design this motor yourself, you may order only the parts you need (Hall effect IC, PNP power transistor, magnet wire, magnets, heat sink).

Hall effect sensors are commonly provided in a digital configuration where an on is output when an object is present and an off otherwise. Digital TMR Rotation/Speed Sensor. This curve tells you how efficiently a turbine converts the energy in the wind to electricity. (Some Hall Effect sensors will have a permanent magnet embedded into the sensor while other use an external magnet.
