The 30A range Current Sensor Module ACS712consists of a precise, low-offset, linear Hall circuit with a copper conductionpath located near the surface of the die. Applied current flowing through thiscopper conduction path generates a magnetic field in which the Hall IC convertsinto a proportional voltage.
