Product number of mCookie Sensor—Hall:MSDS41 mCookie Sensor-Hall is a linear hall sensor, which can detect the strength and polarity of the magnetic field. Sensor hall is a magnetic field sensor based on Hall effect. Hall effect is a kind of magnetoelectric effect, which is found by Hall（A.H.Hall）on 1879 when he was studying the conduction mechanism of the metal.
