Analyzer - meter of 230VAC network parameters - single phase.

@futek2 how did you handle the non-blocking ADC readout? Did you compile this on some old version of Arduino, or some other way?

Hello coll. jarekgo l and Sentimental .
Replying to colleague jarekgol it compiles on version ARDUIONO IDE 1.1.18.
Everything is without problem after the normal installation of libraries.

Replying col. Sentimental .
The components used are typical ones available in any electronics shop. And the potentiometers used are only for calibration of the analyser, because I have just taken into account in the project that the values of the elements can be different at the factory, so calibration is a comparison of the values shown on the web page of the meter and the digital readings of the meter with the range of voltmeter and ammeter.
I have used the meter for another year and I do not notice that the calibration results differ significantly and I check it about every 3 months.

I wish you a brave step, because the meter-analyser circuit is easy to make and you will have a lot of fun when you check it at home.

@futek2 have you had a chance during this time to check it on a clean capacitor or choke? Because I have it put together, but it was showing me wrong at the time and we didn't come to any constructive conclusions. I wanted to write something myself, but I fell down on the fact that non-blocking functions on the then contemporary arduino didn't compile. But as you write that version 1.something this explains a lot.

Hi. I have been doing a lot of measuring lately, because the energy undercutting people who own food shops have active refrigerators, wedges, and they already have a position on the invoices to pay for reactive inductive and capacitive energy. In order to reduce this, it is necessary to make sure to buy a compensator, but only to take measurements by switching off devices one by one and observing which ones generate a lot.
And this works and confirmation that it improves is enough to switch on the kettle and immediately the sinusoids of current and voltage balance out and come closer to each other. And as for your meter, assemble it again, maybe you have made some mistake, because it works from the first time.
Tell us how it went. Because I see from the points for downloading it is a lot of downloads and generally there is no attention to the project.

Then, as you do a lot of measuring, please measure a simple capacitor from a motor (but without the motor), and post a screen shot. A choke from a fluorescent or sodium lamp wouldn't go amiss either.

Hi all, I have a request to the author if there would be an option to add communication over mqtt and display all the readings in topics ? thanks to such a solution you can read the data even with the help of graphene or Home Assistants, which will allow you to consolidate and compare the data of a longer period of time thank you

Hello kol jesiakdawid .
I have already closed the project and I do not improve or correct anything, because no one reports the errors.
It has been going on for more than a year now, it would be difficult to make any changes in the code and I do not remember where to do what in the code.
I understand that you have made the meter and is satisfied as for such little money and works quite correctly.
Maybe one day I will return to the topic, but everything works correctly, so what to invent.
But when you do the configuration via the website, because there is such an option, you can configure the sending of data to the server to draw graphs 24 hours a day.
and 4 values will be sent:

1 - Voltage_network
2 - Phase current
3 - Power Factor - it is necessary to describe the graph manually as it is 1 in the middle of the scale
4 - Apparent Power.

Here a quite similar project, with source code: f1atb .

Hi,


I have a question regarding the Analyser,
is this device suitable for checking whether the household meets the conditions included in the agreement with TAURON?
(here is a fragment of it - tariff G11)

Very similar to the title project - I think if there is no notation then you would need to look in the code.
I don't know about the cost of buying the finished product.
