Can you elaborate about the application you are planning to use? To generate current you'll need some sort of pressure either AC or DC. PZEM-004 won't work with dc, you'll better off looking for a Shunt type ammeter.
If dealing with AC the PZEM should work with as little as 80vac but don't quote me on that as it's been a while.
Thanks for the fast response!
Yes it's a DC application. I just had the PZEM-004 lying around and i thought i could maybe make it work, plus the serial connection helps as i want to have multiple amp sensors on the same ESP32. Maybe I will incorporate some kind of inverter or just go with another type of amp meter as you suggested, probably a current transformer.
PZEM-017 is your best bet as it is designed for DC.
or acs712 maybe?
Hello to everyone,
I was wondering if there is a hack to power the chip from something other than an 220 V AC Power Supply in order to read only current.
For my application i dont have access to AC Power and i want to use the board just for reading current.
Thanks, Chris
