Hall Magnetic Sensor Module


The Hall Magnetic works on the basis of Magnetic field around the sensor. If there is no magnetic field around the sensor then the output from data pin is high (i.e. 3.5V) and if there is some magnetic field then the output from data pin is low (i.e. 0V). Here the polarity should be considered mainly, the opposite polarity of magnetic field should be placed to the polarity of front side of sensor.
