Introduction

Hall sensor module use the hall device A3144. The principle of the hall sensor 3144 is the Hall Effect, when the current is perpendicular to the magnetic field through the conductor, a electric field will be generate at the direct of being perpendicular to current and magnetic field. The hall sensor output low and turns on when a magnetic field is perpendicular to the hall sensor exceeds the threshold. When the magnetic field disappeared, the hall sensor output high.
