Based on the relation between hall voltage and magnetic flux density hall effect sensors are of two types.
Linear hall effect sensor circuit.
Provides a constant driving current to the sensors amplifies the output signal.
As a result such sensors require a linear circuit for processing of the sensor output signal.
The a139x family of linear hall effect sensor integrated circuits ics provide a voltage output that is directly proportional to an applied magnetic field.
Hall effect sensors are available with either linear or digital outputs.
It thus becomes useful for measuring the strength of magnetic fields and in applications that require an output switched through magnetic triggers.
This ic can detect magnetic fields.

Linear hall effect ics are magnetic sensor devices designed to respond to magnetic fields to produce a proportionate amount of electrical output.
Such a linear circuit.
Hall effect sensors are linear transducers.
In the linear sensor the output voltage is linearly related to magnetic flux density.
The heart of every micro switch hall effect de vice is the integrated circuit chip that contains the hall element and the signal conditioning electronics.
We will then connect this ic to an arduino so that we the arduino can read the voltage output by the a1302 and we can display the readings to the computer screen.
Although the hall effect sensor is a magnetic field sensor it can be used as the principle component in many other types of sensing devices current temperature.
Each ratiometric linear hall effect sensor contains a monolithic integrated circuit on a single chip.
Hall effect sensor circuit.
This circuit incorporates a quadratic hall sensing element which minimizes the effects of mechanical and thermal stress on the hall element and temperature compensating circuitry to compensate for the inherent hall element sensitivity.
A hall effect switch will turn on in the presence of south magnetic field on its face or north magnetic field on the opposite side.
The hall effect sensor we will use in this circuit is an a1302 hall effect sensor manufactured by allegro.
Before amplification the sensitivity of typical hall effect ics measured in mv g is directly proportional to the current flowing through the hall effect transducer element inside the ics.
It will turn off when the magnet is removed.
The output signal for linear analogue sensors is taken directly from the output of the operational amplifier with the output voltage being directly proportional to the magnetic field passing through the hall sensor.
