    Seeed Studio Grove - Hall Sensor

    #SEN14034P
    $4.49 $5.95
    ( 1 In stock)

    The Hall Sensor measures the Hall Effect, which is a production of a voltage difference across an electrical conductor, transverse to an electric current in the conductor as well as a magnetic field perpendicular to the current. The output of the continuous-time switch Hall sensor on this Twig switches low and turns on when a magnetic field (south polarity) perpendicular to the Hall sensor exceeds the BOP threshold, and it switches high and turn on when the magnetic field disappears.

    Key Features:

    • Grove compatible interface
    • 400ns transition period for rise and fall.
    • Continuous-time hall effect sensor

    Application Ideas:

    • RPM meter.
    • Simple dc motor.
