RMS Voltage Sensor Part 3: Arduino Code

We build an RMS voltage sensor using a ZMPT101B and an Arduino to measure and chart the voltage of your wall outlet. We explain what RMS is, what typical ranges of wall outlet voltage, and solve some challenges in configuring and calibrating the voltage sensor. We also show how to stream the resulting data into Excel Data Streamer, and record a long duration CSV file for analysis and plotting.

Your has thrown more insight into the zmpt101 library and your code gives a better way to go. But, what if am using the sensor for 220V? What will change in DC offset and sensitivity? Thanks in anticipation.

How did you set up all those Excel spread sheets? I found that interesting I don't know anything about doing that. I enjoyed these 3 videos about reading AC RMS with an Arduino microcontroller.

Thank you man. You save my day

Thank you for the RMS Voltage Sensor Series. This video, Part 3, mentions a follow up video, but I don't see it. Did the video never get made?

[@rftech1608]

Hi Again where do I find the video with the live voltage readings? Video 4 is this playlist? I'm missing the finally! Thank you so much for your explanation of this subject

[@adambeedle]

Great video mate 👍

You my idol

[@sheikhsahab6342]

Could you tell what to do when Vref is not regulated..
And how to take dc_offset into the void loop

[@rodrigofernandes2388]

what happens If you measure 4 different signals at the same time ? is it possible ?

[@sandeshgondane3520]

How did you take out that DC offset from it? Sir, Can you help me please

[@alaswdi]

can you give me the code sir ??

[@EETechStuff]

Why?

[@bromsnor7852]

Works only with Library ZMPT101B 0.0.1 and not with the latest version 1.0.1

[@EETechStuff]

How did you modify the code to get it to work?
