AC meter clamp in sleep mode

Other Hardware Sensors
1

Hello,

I am using an arduino board to read the output voltage of the AC meter clamp.
One of the AC meter clamp output pin is connected to an analog pin of the arduino board
The other AC meter clamp output pin is connected to Vcc using a 470 Kohm resistor and to nd using a 470 Kohm resistor and a capacitor in parallel.

What is the configuration of the analog pin of the arduino board that I need to have during the sleep mode in order to reduce energy consumption : output or input ? value = low or high ? WPU active ?

Does I need to add a resistor before the analog input pin of the arduino board ?

Thanks

Input.

If my guess of your circuit is correct, yes you have to add a resistor to convert the current the clamp produces into a voltage the Arduino can read. A wiring diagram of your setup would help.

Why would you send the board to sleep? I guess you won't power it by battery.
