FREQUENTLY ASKED QUESTION

Q. What voltage i need to supply to module to power it on?
A. Give regulated +5V to module at its VCC connector.

Q. What is output voltage without any load?
A. It is VCC/2 so it means around 2.5V

Q. What happens to output voltage if i connect a DC load current?
A. When DC load takes current the output voltage will deviate from 2.5V to either 0V or 5V depending on polarity of sensing load.

Q. Does DC load and AC load has same type of output?
A. No. With DC load you can check simply with multimeter, But in case of AC load its totally different. Your multimeter will show same 2.5V output whatever load you put on AC because what happens here is when positive AC phase is going on the output voltage increased from 2.5V and during negative phase the output voltage decreases from 2.5V so your multimeter will average that and show you same voltage.
