In this project, we will learn how to make our own IoT Based Electricity Energy Meter using ESP32 & monitor data on the Blynk Application. With the current technology, you need to go to the meter reading room and take down readings. Thus monitoring and keeping track records of your electricity consumption is a tedious task. To automate this, we can use the Internet of Things. The Internet of Things saves time and money by automating remote data collection. Smart Energy Meter has received quite a lot of acclaim across the globe in recent years. So, why not build our own IoT Based Electricity Energy Meter?

We need to select the current sensor as well as the voltage sensor so that the current & voltage can be measured and thus we can know about the power consumption & total power consumed. The best current sensor available in the market is SCT-013. This is SCT-013 Non-Invasive AC Current Sensor Split Core Type Clamp Meter Sensor which can be used to measure AC current up to 100 amperes. Similarly, the best voltage sensor is the AC Voltage Sensor Module ZMPT101B. The ZMPT101B AC Voltage Sensor is the best where we need to measure the accurate AC voltage with a voltage transformer.

Using the SCT-013 Current Sensor & ZMPT101B Voltage Sensor, we can measure the all required parameters needed for Electricity Energy Meter. We will interface the SCT-013 Current Sensor & ZMPT101B Voltage Sensor with ESP32 Wifi Module & Send the data to Blynk Application. The Blynk Application Dashboard will display the Voltage, Current, Power & total unit consumed in kWh.

3:00 current sensor
4:02 voltage sensor

Shraddha.. your voice is I saw this video again and again just for your voice and your project is too excellent...!🙂

[ManishGpt]

Very informative as you express all the points in a very nice way.

[Atom]

hi, i have tried, but the current sensor, not have responsive read the current yet, how can i fixed it?

[innovateyourself]

Thank you shraddha for this video. This was the most awaited video ❤️ your efforts are really appreciated ❤️

[mosesakpan]

Oh!! What an excellent project I really love it

[jephtah]

Good video, i need to understand something, the GPIO pin of the esp32 is 0 to 3.3v logic level and the voltage transformer is 0 to 5v, so the question is how do you manage the this voltage level incompatibility in the esp32 ADC ?

[killua]

Thanks for this. Just a doubt. Will this work with 3 phase supply? If not, what should be added to make it work?

[dassajityadav]

Best ever project seen today by you thanks this is possible for 3 phase supply

[deepujoy]

But not sure if it is considering of power factor because that factor also affects KWh

[ashwinamani]

May you kindly provide guidance on how to utilize this in a three-phase system?

[find_the_truth.]

Very nice project, I am also trying to make this as my college project, but I am facing the issue that, i want to measure multiple bulbs power with the help of only one sensor what you are using because I have some financial issue, so my question is that, Is it possible to measure power of all bulbs with only one sensor ? Pls help my project has stopped.

[funlifeu]

Can we connect other appliances like refrigerator, AC?

[binisol]

Great one. Just to know what capacitor voltage did you use cause it only says 10uf ?

[nazmussakib]

It's a great project! Do you have any report on this project. I am willing to work on this for future. If you have than do a reply please. Thanks.

[pranaysharma]

It is really cool project
And the quality your video is really damn awesome!!!!

madam just what i wanted and what a sweet voice you have

[masumbiswas]

how we reset it after every month? recoding the whole? How to add a reset button?

[mohanvakil]

The CT clamped on wrong wire in your video, It should be on the wire in series with 'Lamp LOAD', but in video it is wrongly shown on voltage sensor input wire which is parallel to lamp. There fore you can not get the correct readings.
