- PZEM-004T is all in one power sensors module. It has a Voltage sensor, current sensor, frequency sensor, power factor, power, and energy meter.
In this video, we are going to learn how to use this sensor with Arduino and NodeMCU and also make a simple wattmeter.

i love u bro u r my hero, big love from saudi
Great video, is it possible tomeasure voltage waveform ??
Hello, I really liked the video and I want to monitor a power connection. Question, can you script the three devices and phases for the ESP8266 D1 mini, so that the output is displayed on a web page? Greetings
should the sensor power be connected to the load (example a heater), or should it just be connected to power and ground?
Yes . I have been using it for long periods now.
Good one there
Is it still running?
@@miliohm yes .
Very perfectly for over two years now
Hello sir, I just purchased one pzem004t 100A module for my college project, it measure voltage and current correct but in pure resistive load it shows 0.05 power factor, could you please guide me what is the problem? And how can I solve it?
@@Digi.world1 ok
@@samgongelectronics3761 i have problem with my sensor module PZEM-044T like voltage, power factor, ampere increase in running after 1 hour or even 5 minutes running this sensor, you have some problem like me?
Nice project
Thank you!
Please make 3phase power parameters monitoring like this video
hallo sir i have done everyhing accordingly to your diagram and code but i cant get values from the pzem not displaying just printing ( nan) any help would appreciate
Sir,Here how power factor is measured theoretically in this pzem 004t module.
Please make a video how to set address for pzem
what if I use a nodemcu and use an LCD display, what is the cable schematic from the nodemcu to the LCD display?
Can we use this with victron colour control gx device?
But I need to Detect Leading or Lagging powerfactor. Can I do this with PZEM004T?
I want to use 4 pzem004t sensors plz help sir in knowing the pins of arduino on which it is to be connected
In my exp 32devkitv1 it doesn't have D3 if try to chage it to other it shows error what to do ?? Please help me
Is the value measured in Pzem004t in seconds or minutes? Because I have 209 volts, 0.032 amps. And if that's hourly, it's almost hourly Doing 500 watts
I still get Nan message when running the code and the sensor. But, there is something different between my voltage source. I use dimmer instead of Main AC, like shown in the diagram to control a heater. Could that be the cause? Thanks in advance
hello, my pzem turns off when the AC voltage is running, why is that?
hallo very good system quick question sir which pins to connect for display while using NodeMCU
The i2c on NodeMCU is D1 and D2
@@miliohm thanks man i made the project i used 2004 lcd and dispayed all the values good work

I have the same issue, don’t know how to resolve it. Did you already figured out?
Recheck the code there are some flaws
@@vedanttirpude2967 thanks for your answer , it has phase connection problem. If we make connection proper then it should show correct answer.
what if i want to connect 2 sensors to a Arduino??? does the library support instructions for 2 sensors??
Use arduino mega or use multiplexer
Hi, nice explanation but where do I find the whole code?
It's on the description
I hate that it doesn't have sperate powering option. I dont trust capacitive dc power supply
How about for three phase supply?
You can use three sensors. But since this sensor only able to measure 260V max. You should measure phase to neutral.
hello. can data be send for writing to arduino sd card ?
Sure, you can watch my tutorial about sd card/make data logger
Can i use this sensor for dc?
No, you can use pzem 017 for DC
@@miliohm thank you
can we use this to measure DC voltage as well??
There's different pzem product for DC
@@miliohm can you please name it?
@@muhammadmobeenmalikawan8351 you can google pzem for DC. For DC example pzem-017
Hello! I followed all the instructions but still get a NaN output. Any thoughts why this is happening?
Were you connect the sensor to main AC?
Check if the tx pin from pzem is connected to rx pin of esp and rx pin of pzem to tx in of esp. Also check the baud rate
Anyone with a working demo using an esp32 wroom? I don't know if i have a code, library, or hardware issue. I got nothing from the demo code i found.
Try using serial2 pins for the PZEM
whats the problem
hi, im currently doing this project to adapt in my final year project at my uni, can i contact you because i have been following the steps but its not working, please!
i need your help how to contact you sir
