Hello
I am doing a project on over current protection by using ACS712 with Arduino.
Can u please help me to measure ac current which will in the range of 0 to 30A
The current value may be directly displayed by an instrument, or converted to digital form for use by a monitoring or control system. Current sensing techniques include shunt resistor, current transformers and Rogowski coils, magnetic-field based transducers and others.
In electrical engineering, current sensing is any one of several techniques used to measure electric current. The measurement of current ranges from picoamps to tens of thousands of amperes.
