Description : http://www.seeedstudio.com/wiki/Grove_-_Hall_Sensor 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. Features Grove compatible interface 400ns transition period for rise and fall. Continuous-time hall effect sensor Application Ideas RPM meter. Simple dc motor. Mechanic Dimensions 20mm by 24mm For all Grove users (especially beginners), we provide you guidance PDF documents.
