For discussions related to emonPi, emonTx, emonBase and emonGLCD hardware and Arduino firmware
hello I’m new to all this, Please give me if I’m posting this in the wrong Section. My first time on this site. I’m working with the Basic hardware for Monitoring current on my Ac system. I followed this page here. So far everything is current. I have the same hardware as far as current sensor, Resistors and caps. My skills lay in hardware not software. But I’m learning as much as i can.
I have tired the arduino code that is on the page with the library. I do notice where the voltage is at in the code originally it was set for 230v. So i changed it to my voltage which I’m in the USA at 120v. However i do not know how to do the Calculate for this line
double Irms = emon1.calcIrms(1480); // Calculate Irms only. Can someone please help me. My ac unit the breakers are at 30a.
