• A Hall effect sensor is a transducer that detects the presence of a magnetic field.

• Based on the Hall effect, which is the creation of a voltage difference (Hall voltage) across an electrical conductor when subjected to a magnetic field perpendicular to the current flow.

• Sensor contains a small semiconductor element known as a Hall plate or Hall element.

• When a magnetic field is applied perpendicular to the Hall plate, it generates a Hall voltage across the plate due to the Hall effect.

• Hall voltage created across the Hall plate is directly proportional to the strength of the magnetic field applied.




3144 Hall Effect Sensor:




• 3144 Hall effect sensor is a digital Hall sensor commonly used for detecting the presence of a magnetic field.
• Provides a digital output signal, meaning it outputs a logic HIGH or LOW depending on the presence or absence of a magnetic field.
• When a magnetic field is brought close to the sensor, it triggers the Hall effect within the sensor, causing it to produce an output signal.
