Hall Effect Sensors
Hall effect sensors are used to determine the presence of magnetic fields that use the Hall effect. The Hall effect, discovered in 1879 by Edwin Hall, refers to movements of charge carriers across a conductor to a magnetic attraction. The effect produces a measurable voltage differential that renders a negative and positive charged side.
Once the Hall effect is detected, the sensors transform the findings to electronic data. The sensors can detect a mechanical system’s displacement, speed, and proximity. They are non-contact sensors, so they do not have to initiate contact with physical elements. The signals they produce can be analog or digital – analog signals are continuous while digital ones go on and off.

Hall effect sensors are made of thin rectangular-shaped p-type semiconductors, such as indium arsenide or indium antimonide, graphene, indium phosphide, and gallium arsenide.
Hall effect has a magnetic sensor known as the Hall voltage. It is directly proportional to the magnetic field’s strength, which is measured by a Hall probe. Applications that benefit from Hall effect include the following devices:
- Keyboard switches
- Position sensing instruments
- Automotive fuel-level indicator
- Direct Current (DC) transformers
Types of Hall Effect Sensors
There are two types of Hall effect sensors: devices with digital outputs and analog devices/devices with linear outputs
- Digital output Hall effect sensors use a Schmitt trigger to generate a steady output increase and decrease as the voltage rises and falls. They come in two types: unipolar and bipolar. Unipolar digital hall sensors use one magnetic South Pole. Bipolar digital Hall effect has positive magnetic fields to operate and negative fields for release.
- Linear output Hall effect sensors have a continuous voltage output. When placed in a weaker field, the output decreases. When placed in a strong magnetic field, the output increases.
