Oh!! What an excellent project I really love it

This is really useful. Thank you so much 😊😊😊 for this video.

I like your video, it's very clear, starting from the pictures of the circuit of each tool, device design, and program. I like it. Always healthy, good people❤

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

Wow! simply explained👍

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

very helpful video. THANK U

Really helpful tutorial

How if I want to measure 3 phase current and voltage using that sensor? What pin will I use?

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.

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 ?

@BLOCKsignallingUK

The two 100k resistors make a voltage divide by 2, so with Vcc at 5V, the mid point of the resistors is 2.5V. The 2.5V is fed to the ADC input via the 100R resistor. The current clamp is across the 100R resistor and when the clamp measures a current it generates a voltage across the 100R resitor, adding (or subtracting depending on the ac cycle) to the 2.5V. So the 2.5V could vary between 1.5V and 3.5V with 100A flowing through the clamp. The 10uF is probably for noise supression. That is my thinking anyway. Let me know if I have misunderstood.

no pin other than ADC (ADC0) can be used to measure analog voltage, as the CT & Voltage transformer has Voltage output(i.e. Analog). As we all know there is only one pin there on NodeMCU ESP8266 to measure analog signals, which is not at all used in the above schematic.

use a 200W and a 60W filament bulb in parallel and measure the current using a multimeter. In my test, it showed that this setup draws 1.03A AC, so hence you can calibrate your current clamp accurately by fiddling the current calibration value accrodingly Now to calibrate the voltage, its a simple task of fideling the calibration value till you hit the sweet spot

In the video, we can see the USB cable connected to the ESP32 chip. Is this to provide the DC supply for the chip? Could we use the output of ZMPT101B with a basic AC-DC rectifier circuit to power up the ESP32 chip? Or this would affect the measured power quality? Thanks.

@simonmasters3295

Haha. I just spent a day trying to find a sufficiently accurate solution. You need to measure mV across a fixed resistance shunt, and an op-amp to boost the mV (which may be negative or positive depending on the direction of current flow) to a signal between 0 - 3.3v that the ESP or Arduino can measure on an analogue input pin. That said my non-invasive meter has a DC voltage measurement, but I don't want to spend all day reading and recording the read-out. I think there is a code error which accounts for the zero kWh readings.

why your reading are incorrect? how to calibrate to get correct readings

My blynk app is not showing values why
