Hello, I am looking for someone to write an article on Hall Effect Sensor. It needs to be at least 1250 words. As a result of the above, the movement of electrons through the semiconductor is affected by the availability of an external magnetic field which is usually at right angles to it. The effect of this magnetic field is much felt in flat rectangular material. Hall effect sensors are available either with digital output or linear output. Those who operate with linear output are called analogue sensors. The output signal for analogue or linear sensors is retrieved directly from the operational amplifier’s output. The voltage output, in this case is directly proportional to the magnetic field moving through the Hall Effect sensor. The output voltage is given as

VH=RH[I/t X B].

Where

VH is the Hall Voltage (given in volts).

RH is the co-efficient of the Hall Effect

I am the amount of current flowing through the sensor (given in amps)

t is the thickness of the sensor (shown in mm)

B is the Magnetic Flux density (given in Teslas) (Electronics-Tutorials.ws., 2011).

&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp. Moseley and Crocker (1996) explain that the analogue or linear Hall Effect sensors continuously give a voltage output that rises with a strong magnetic field and decreases whenever there is a weak magnetic field. One phenomenon that is notable in this type of sensor is that when there is an increase in the strength of the magnetic field, there is also a rise in the output signal from the amplifier until it begins to saturate the by the limits that the power supply has imposed on it. Any additional magnetic field will not have any effect on the output. Instead, it just drives it into saturation.

&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp. On the other hand, the digital output Hall Effect sensors have a Schmitt-trigger with an internally built hysteresis that is connected to the op-amp. The design principle in this type of senor is that when the magnetic flux moving via the Hall sensor surpasses the value that is already present, the output from the device quickly switches from its “ON” condition from an “OFF” state without any form of contact bounce.

Operations conditions

Weiser (1991) explains that for a Hall Effect sensor to produce an output signal, a reference voltage must be supplied to it. This voltage is provided from the vehicle’s onboard computer. This could be which maybe 5 to 12 volts depending on the application.&nbsp.
