This magnetic field is detected by an integrated Hall sensor IC, which converts it into a proportional analog voltage output. At zero current, the output sits at approximately 2.5V (half of the 5V supply). As current flows in one direction, the output voltage increases above 2.5V; in the opposite direction, it decreases below 2.5V. With a sensitivity of 66 mV\/A for the 30A variant, a current of +10A produces approximately 2.5V + (10 x 0.066V) = 3.16V, while -10A produces approximately 1.84V.
