The Hall Effect Sensor

Linear sensors can measure the wide range of magnetic fields.

The hall effect sensor.

A hall effect sensor is a sensor that response to a magnetic field. When the hall sensor is put in a magnetic field the electrons running through will move to one side of the sensor. Hall effect sensors are used for proximity sensing positioning speed detection and current sensing applications. It was discovered by edwin hall in 1879.

Hall effect sensors are devices which are activated by an external magnetic field. They are generally classified based on their manner of output or means of operation. Working on the principle of hall effect these sensors generate a hall voltage when a magnetic field is detected which is used to measure the magnetic flux density. The sensor will then have one positive and one negative side and create a voltage known as hall voltage.

A hall effect sensor is a device that is used to measure the magnitude of a magnetic field. The hall effect is the production of a voltage difference across an electrical conductor transverse to an electric current in the conductor and to an applied magnetic field perpendicular to the current. We have hall effect sticks compasses and even hall effect sensors on gas motors which co. For clarity the original effect is sometimes called the ordinary hall effect to distinguish it from other hall effects which have different physical mechanisms.

Hall effect sensors are magnetic components that convert magnetically encoded information such as position distance and speed so that electronic circuits can process it. Hall effect sensors are simple inexpensive electronic chips that are used in all sorts of widely available gadgets and products. We know that a magnetic field has two important characteristics flux density b and polarity north and south poles. The hall effect sensor usage today.

The hall coefficient is defined as the ratio of the induced electric field to the product o. Hall effect probes are more expensive and sophisticated instruments used in scientific laboratories for things like measuring magnetic field strength with very high precision. Hall effect sensor is basically the transducers whose voltages varies by changing magnetic field. Hall effect sensors are the linear transducers that are used to measure the magnitude of the magnetic field.

Its output voltage is directly proportional to the magnetic field strength through it.
