With Arduino

The following sketch demonstrates a simple application of measuring the amplitude of the
alternating voltage.The SIG pin will output a alternating voltage based on the alternating current
being measured. You can measure the value using ADC.
 Connect the module to the analog A0 of
 Put the alternating current wire through the hole of the current transformer.
 Copy and paste code below to a new Arduino sketch.
