What is a Hall Sensor and how does it work in phones?

    1. A hall sensor is an electronic device fitted in a phone to determine the proximity, speed, and location of a device’s mechanical system.
    2. It does this by detecting varying magnetic fields.
    3. It then converts the variance into electronic signals that are relayed to the phone’s processor.
    4. A hall effect sensor does not have to come in contact with a physical element to detect and relay information.
    5. Hall sensors are important in the Global Positioning System (GPS) function of a phone or even a vehicle.
