Hi Robojax! Im doing my final career project and Im building an EPS for a Cubesat. I have to use this type of current sensors with Arduino and MATLAB (college requirement) and I tried to measure 20mA current from Solar Array, but I couldnt read anything (because sensitivity I guess). Im using ACS712 30A with 66mV/A. Is is possible to use the 30A unit or the 5A unit for measurements of 20mA to 500mA? I guess this values are to low that the sensitivity doesnt variate the voltage enough to give measures. Thanks in advance! :)

It's good you mentioned the bad design of the PCB.... In addition to the problem with high current you mentioned, there appears to be terrible separation between the 5V measurement side and the potentially high voltage side. The chip boasts a 2.1kV isolation, but that PCB looks like it could easily fail well below that (possibly even at 240v mains once it gets a bit of dust on it).

Hladám skúsenosti ohladne merania AC prúdu s ACS712. Ale tu nachádzam kadečo, (kdejaké odkazy) , napr učenie s arduino..... Proste nedá sa v tomto vyznať, hoci názov je jasný: "Meranie striedavého a jednosmerného prúdu 5A-30A pomocou ACS712" a nie nejaké učenie arduina. A hlavne , tu by stačil jeden riadok : odkaz na robojax

please how to Measuring high voltage arduino

@robojax 4 жыл бұрын

Here kzfaq.info/get/bejne/fMefft2anNrLfXk.html you can measure any DC voltage .

@udomjanjarassuk1604 3 жыл бұрын

The AC current should be measured in RMS, not in average. That's why the reading is less than the actual value. Assuming that the current is a sine wave, a simple fix is to multiply the average by 1.11

You may be right, but the datasheet does not say anything about extra factor for AC or DC. I have implemented whatever was in datasheet. Thanks for the comment on the matter.

Sir can you please share AC Current measurement Arduino code

@robojax 2 жыл бұрын

This is for AC and DC. It depends on the sensors . I have explained it . Please watch carefully.

عوامل مختلف باعث خطا در خواندن مقدار میشود. ۵٪ خطا در‌این کشاف (سنسور ) طبیعی است. من فازسی زبان از خراسان بزرگ‌هستم که مشتمل بر تاجیکستان،ازبکستان،افغانستان، نصف ترکمنستان و قسمتهای شرقی ایران امروزی است. سلامت باشبد

@@robojax از هم زبانی و اشنایی با شما خوشبختم .برای برطرف کردن این مشکل راهی هست ؟؟

@robojax 2 жыл бұрын

بلی است. باید کشاف با دقت بالا بگیرید. و ساده ترین راه آن است که شما اگر 100ملی آمپر را مثلا میخواهید اندازه گیری کنید از کشاف مثلا 5 آمپر استفاده کنید نه از 20 آمپر. هر قدر مقدار حد اکثر کشاف بالا برود به همان اندازه خطای 2 تا 5% بزرگتر ظاهر میشود.

You didn't explain absolutely anything about the wiring. Oh yeah, and your library is full of mistakes and doesn't work :) Good job buddy

@robojax 3 жыл бұрын

when you skip the video this is what happens. I have just watch it and wiring is explained wire by wire and even wire color is explained. Library has been tested and works according to the datasheet. Good luck agne.
