Measure Mains Voltage with raspberry Pi and PZEM-004T ?
Posted: Wednesday 03 January 2024 23:44
Hi newbie here. please be gentle
All I want to do is measure mains voltage 230v and display a graph, thats it
My Pi will be in a remote location, using a USB 4G modem. I need a low cost solution,
Whats the easiest way to this.
After some research tonight I see one solution is to use a PZEM-004T and esp8266, how would this connect, what do I need to do? Cant I just use the serial on the Pi?
Any help would be really appreciated.
