Hi,I am working on a project in which I use ACS712_30A with esp32 but its not working fine (It can't calibrate right power) can You help me with some solution.
..would be nice, to implement a kind of “if-then” string in the sketch that activates an output, when a certain current-limit is reached (for example to switch off parts of the load with a solid-state relay when the current gets too high). A kind of switching-hysteresis to prevent pumping would be necessary, too, I guess. As I'm an Arduino-beginner, I'd really appreciate getting some help :)
Hello, the person trying to use this should have learned a lot before coming here. Arduino Step by Step course that starts here ruclips.net/video/-6qSrDUA5a8/видео.html
So you want energy meter? You need to measure the voltage. I have a video on that so you can measure any voltage her ruclips.net/video/t8xwrVj2aFs/видео.html and I am right these days busy working on a Energy Meter Project. The first step for meter project was to measuring voltage (video above) then current using shunt so you can measure up to 500A and the video is here ruclips.net/video/9jwCc7uPGoc/видео.html energy meter is coming for Shunt resistor.
Hi, you may have come to the wrong video then. the rule is this. first you should be able to read the current without LCD and just print it on the serial monitor, then use the LCD. Here the introduction video to ACS712 Sensor with library ruclips.net/video/3C33DpcSwIw/видео.html
I would like to make a device that connects to the rectifier 12V lead-acid batteries from 0 to 15A. The device would be connected to the current cables coming out of the charger and only from the device would I connect to the battery. The device would measure the current voltage V on the battery, the current A which is currently being charged, the amount of Ah that the battery has taken and the charging time. Can you design such an arrangement for arduino? Thank you.
This can work to measure current only. you can connect any configuration either in + line or - line. But it can't measure voltage . Here my video on voltage sensor: ruclips.net/user/robojaxTVsearch?query=voltage
Hi, you can power arduino board via the IN pin or the power adapter pin using 6 to 12V. Then from 5V output of Arduino you can power the sensor or any other modules.
This device from the current it generates voltage and from voltage current is calculated. There is no voltage for the source. Watch the video again and do not escape.
it can't be like this. please provide the actual error. have you installed the library? this tutorial needs you to watch 2 video 1-introduction to LCD 2-Introduction to ACS712. so you must do both before coming to this video.
I copied and pasted your sketch into the Arduino IDE. It appears to have loaded but it comes up with an error saying " No such file or Directory. This is my first Arduino project so I may be the problem here or not. How do I correct this?
Hello, good day Sir! I am planning to somehow progress this project by adding a GSM Shield module so that if the current sensor detects 0 current/load it can then send an alert to me through SMS. Is that possible, Sir? Your response would be very much appreciated!
Yes it is possible but you gotta write the code or hire someone to write it for you. Please watch the pasted video with library I have written so it will be clean code Measuring 5A-30A AC and DC current using Allegro ACS712 with Robojax Library (code added into video) ruclips.net/video/3C33DpcSwIw/видео.html
I wrote library this (which have not sent as this is just raw code) but did not see much interest and did not go for esp. not sure if anyone else has written anything.
I mentioned this is for AC and DC. It seems you haven’t watched the introspection video. You must watch it before coming to this video ruclips.net/video/3C33DpcSwIw/видео.html
You must watch the following two videos before you can understand this video: 1- introduction to ACS712 Current Sensor: youTu.be/DVp9k3xu9IQ 2- LCD1602 with 2IC display : youTu.be/q9YC_GVHy5A
yes you can if you set the voltage I've explained to 3.3V if your board is 3.3V. This is 3 project. 1-reading DC voltage, 2-LCD 3-Current. you have to make sure each work before coming this which has all 3 combined. this way you can find the issue.
@@robojax Thanks for your prompt response. My LCD has 2 rows, but 14 pins only. I have I2C converter to 4 pins. I heard that the last 2 pins of LCD panel are for backlight, which I do not need it. Do I need to change the sketch?
Thank you so much for the video I think this will do the job for my MA meter that I asked you about thanks Bob in the UK
You are very welcome. Good to hear that. Please share Robojax on your social networks. Ahmad
Got that portion of it working. Just like you said I needed to download the LiquidCrystal_I2C.h>. Thanks for your quick reply.
You are welcome. I am glad you were able to resolve the issue.

Hi Sir, how to do the same measument for 3 phase? Pls help.
Perhaps one solution would be to use 3 of them for each phase and then mathematically calculate the current of 3ø
what is max current can it handle for safe use continuous wtih 12v voltage?
Voltage does not matter. The current value is what you purchase.
@@robojax so if i buy acs712 30A, it can safe for continuous 30A everyday? No need to add shunt?
Hey I would like to know how to measure voltage current and power to display on lcd

Can I connect it in AC? To measure the Current and the output voltage? The input voltage is 220 V ac.
Yea you can.
why my display on my LCD is always say "No current'? i need your help to fixed my code...
because you don't have current, if you connected the device incorrectly. Check it again.
hi, thank you so much for the video.. But I want to ask can I use battery 9 V as the power supply?
Hi, you can power arduino board via the IN pin or the power adapter pin using 6 to 12V. Then from 5V output of Arduino you can power the sensor or any other modules.
In code it says voltage. Plz make a video how to display voltage with current known
This device from the current it generates voltage and from voltage current is calculated. There is no voltage for the source. Watch the video again and do not escape.
Thank you for the video .for the app ,how can i build it please?
what do you mean how can I build it? You buy the components and connect them, use the code I provided and it should work.
How can I measure the power consumed? Great video by the way
Thank you. You can do some calculation in code P=VxI and display it. You can also do energy W/h as well.
@@robojax okay thank you so much
You are welcome.
nice vdo thx for these information
You are welcome.
why my arduino cant upload and error at
it can't be like this. please provide the actual error. have you installed the library? this tutorial needs you to watch 2 video 1-introduction to LCD 2-Introduction to ACS712. so you must do both before coming to this video.
Sir, what should we do to measure overload
You can learn it from this video ruclips.net/video/vs7Nw107AOo/видео.html
I copied and pasted your sketch into the Arduino IDE. It appears to have loaded but it comes up with an error saying " No such file or Directory. This is my first Arduino project so I may be the problem here or not. How do I correct this?
Watch the video where I explained the code. you must have escaped.
I would like to measure a 3w lamp and show watt as result, can i use the same code and add v*current to show watt result.
yes that is why I provided this so you everything is ready for you.
@@robojax i was dm u at Instagram...i still learning... please explained it at new video
Can it show both voltage and current at same time
it is up to you want to display it or not. here is the video showing you how to measure voltage ruclips.net/video/t8xwrVj2aFs/видео.html
Is it measures current in 3 phase voltage (415v)
So you did not watch introduction to ACS712 please watch it here ruclips.net/video/3C33DpcSwIw/видео.html

@@robojax Thank you so much for the response Sir. I'm from the philippines, do you have someone you know that we can hire to code?
Is there need for change in input voltage?
Your question shows that you have not watched the video or escaped. Please watch it and you will find the answer.
How can i get the sketch for this project
The link to the code is under the video in the description: snag.gy/t94goi.jpg
Is it better to use this sensor or shunt resistor?
Here watch and decide ruclips.net/video/9jwCc7uPGoc/видео.html
What is power range for 5A module? Can I use it for 85V DC and 5A for 5A module...please share your idea...
The link to the datasheet has been provided in the same page where the code is. You can check it there.
@@robojax In data sheet...Viso = 365 V peak then power range for 5A..is 1825w...Then it is also suitable for 85v * 5A =425w.. Is it right?
power doesn't matter because we look at current. If current is 5A or lower it is okay.
@@robojax Okk...Thank you so much...☺
Is there any acs712 coding for esp32?

That I sent you the video . Watch and get answer
Sir how much load should be given
this video require you to watch the actual video tutorial on ACS712. The link is in the description.
Use only dc load ?
