What Is A Hall Sensor
it is a sensory device used to detect the
presence and magnitude of the magnetic field.
the name is given after the discovery of the
“hall effect” done by american scientist mr. edwin
hall.
it is like a binary switch that detects the
presence of a magnetic field and produces a binary signal (1, 0),
the voltage is either high (~5v) or low (ov)
depending on the type of the sensor. it specifically only react to a pole of
the magnet.
also, read how
the hall sensor works?
they are widely used in the bldc electric
motors to detect the position of permanent magnets and provide necessary output
signals to the driver system.
you can find them in the application of
speed detection, proximity sensing, positioning, and current sensing.
it has three pins input, ground, and output.
