Nice One but whats the Capacitor voltage you used cause it only shows the 10uf on the circuit???

Uhm what are the jumper cables did u use??

Is it permissible to change the calibration factor in the code? this line I mean: #define vCalibration 200 #define currCalibration 0.50

how is it , with three phases,? that is to say with 3 three current sensors and three voltage

hi nice project but can we configure it to read power and energy in bidirectional mode.

Can you share where did you make circuit simulation

Can you make the same project for 3 phase power monitoring?

do you mind sharing the pub design for this 2.0 version

How to send current measure to email use in ESP32 board

hello guys i just build this project but i got some confusion when i add blynk function my serial monitor print zero but when i remove all the blynk function it read voltage and current all good where did i do wrong guys ....the issue is when i add blynk to send those data to blynk app it print all zero value but when i only do without blynk it work fine... any help guys i just stack here

Wifi connected nahi hoga to LCD me parameters nahi show honge.

Vro how can I get auth code

let's assume the wifi is faulty but there is power, does it have local (Offline Storage) that can be used during this time, so that when the wifi is back on it just syncs up? or does it just resume from where it lost connection?

Adjust the contrast using the potentiometer at the back of the display. Or it could be the I2C address issues, the LCD display has 2 i2c address, please check and modify the i2c address in code.

For everyone whos checking out this project, be aware of the following: 1.The code used in the linked webpage is masking APPARENT POWER into REAL POWER and thats completely wrong. 2. Whats worse is that the energy calculation in the code takes apparent power as real power sooo guess what? the energy calculation is also wrong. 3. The ZMPT module introduces a phase shift in the voltage signal. This is because on the secondary side the signal is fed into an amplifier. This doesnt affect RMS voltage readings at all but it completely screws up the REAL POWER calculation. Im not saying this is a bad project at all, it works pretty well to get VRMS,IRMS and Apparent Power readings however forget about calculating real power, power factor and energy because as I said earlier, this is screwed up by the ZMPT module itself.. You may try to correct that phase shift by software but I cant guarantee you will get decent accuracy in the readings. If you want to calculate real power then you should use a crude step-down transformer.
