PZEM-004T Sensor Tutorial (Current, Voltage, Frequency, Power, Power Factor and Energy meter).

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.

Yes . I have been using it for long periods now. Good one there

Is it still running?

[@samgongelectronics3761]

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?

[@cepotastrajingga1704]

@@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?

[@lutzmuller5703]

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

[@CompostelaOnline]

should the sensor power be connected to the load (example a heater), or should it just be connected to power and ground?

[@rakamulyaputra5478]

Great video, is it possible tomeasure voltage waveform ??

[@creativeelectronicchannel7647]

Nice project

[@miliohm]

Thank you!

[@anastasiawairimu4751]

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

[@hexonsystem3284]

what if i want to connect 2 sensors to a Arduino??? does the library support instructions for 2 sensors??

[@bensonmathew9136]

Sir,Here how power factor is measured theoretically in this pzem 004t module.

[@achannel4686]

what if I use a nodemcu and use an LCD display, what is the cable schematic from the nodemcu to the LCD display?

[@creativeelectronicchannel7647]

Please make 3phase power parameters monitoring like this video

[@user-du2pz6ci1b]

But I need to Detect Leading or Lagging powerfactor. Can I do this with PZEM004T?

Can we use this with victron colour control gx device?

[@sakshitripathi39]

I want to use 4 pzem004t sensors plz help sir in knowing the pins of arduino on which it is to be connected

[@keeeerthan]

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

[@rasittastan]

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

[@giorgosiotis1557]

Please make a video how to set address for pzem

[@alexanderpurba5533]

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

[@davidkinuthia1052]

hallo very good system quick question sir which pins to connect for display while using NodeMCU

[@miliohm]

The i2c on NodeMCU is D1 and D2

I have the same issue, don’t know how to resolve it. Did you already figured out?

[@vedanttirpude2967]

Recheck the code there are some flaws

[@Digi.world1]

@@vedanttirpude2967 thanks for your answer , it has phase connection problem. If we make connection proper then it should show correct answer.

hello. can data be send for writing to arduino sd card ?

Sure, you can watch my tutorial about sd card/make data logger

can we use this to measure DC voltage as well??

[@miliohm]

There's different pzem product for DC

[@muhammadmobeenmalikawan8351]

[@miliohm]

@@muhammadmobeenmalikawan8351 you can google pzem for DC. For DC example pzem-017

[@gargantieljustinelouisel.1884]

How about for three phase supply?

[@miliohm]

You can use three sensors. But since this sensor only able to measure 260V max. You should measure phase to neutral.

[@tirebatireba6626]

Can i use this sensor for dc?

[@miliohm]

No, you can use pzem 017 for DC

[@reuxgalang5753]

Hello! I followed all the instructions but still get a NaN output. Any thoughts why this is happening?

[@miliohm]

Were you connect the sensor to main AC?

[@syamkrishna5078]

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

[@sauravmodak507]

I hate that it doesn't have sperate powering option. I dont trust capacitive dc power supply

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
