The KY-003 Hall magnetic sensor is a magnetic
switch. If a magnetic field is present near the KY-003 Hall magnetic sensor,
the signal pin will output a LOW signal. The polarity of the magnetic field
affects the switch action, with the front side needing an opposite polarity to
the back to turn on.
The KY-003 Hall magnetic sensor has a beam of electrons
flowing, when there is no magnetic field present there is no electron
deflection occurs, which supply a high voltage to the signal pin, when a
magnetic field is applied these electrons get deflected and there is a fall in
voltage and the signal pin receives a low input
