Hall Sensor Module for ArduinoA magnetic field sensor based on Hall effect. Hall effect is a kind of magnetoelectric effect, which was discovered by Hall (a.h.hall, 1855-1938) in 1879 when he studied the conductive mechanism of metal. Later it was found that semiconductors and conductive fluids also..
