Revolutionary Hall Effect Sensor around you. GuEss wHeRe?

What is a hall effect sensor? Its a sensor simply by using hall effects principle to operate it.. Hey get to the point.. allright..

A hall effect principle is simply having electrical current flowing through a conductive material which is immersed in a magnetic field. The applications of hall effect sensor can be found widely in brushless DC motor, flow sensor, tachometer. To understand brushless DC motor just look at your desktop PC’s cooling fan.

If you try to open it up you’ll find that it has no brush or contacts to run the motor but what runs it is the Hall Effect sensor by giving the circuit board electrictrical pulse to alternately suplly current to generate electromagnetic field in order to rotate the motor.
