The right library used in this video : miliohm.com/files/ACS712.zip

Just minor correction: 6:18 If you are using the 30 amp type, you need to change the value in the code to 0.066 NOT 0.66.

This is the first video I've seen showing acs712 noise through an graph... Thank you very much

Thank you for this video it will help me in my design.

Ok if this guy passed 230VAC through the devBoard I am no longer feared to use this -_-

Sir what sensor should i use for less then 0.4 amp sensitivity ?

Nice video, thanks for sharing :)

Good day Sir. I want to somehow progress this project by adding a gsm shield module so that when the current detected by the sensor is 0 amp, the gsm shield module will then send an alert to my phone through SMS. Is that possible? Your response would be very appreciated.

Using a 240v to 12v adapter, can i short the + and - terminals on the left terminal block?

Hi, Could you recommend the above sensor for measuring a current less than 0.9mA from a board? My project is based on Arduino.

Can I use this sensor for ındustrıal electrical motor to monitoring current and consumption of the motor for predictive maintenece

Can the code be used in esp32 and when no load is connected adc value is 816

nice work

thank you it really great help from your code...thank you..

what is the unit of the current output? is it amps or milli amps

I plan to utilive the sensor for a current of about 1.27 amps, will this be sufficient for the 5amp input module? If not then which adc would you recommend? for the voltage sensor on my device, I understand the arduiono has one available that will need a voltage divider for measurment.

Hi, do you have a video of using arduino uno using acs712 sensor and a voltage sensor? i am doing a project currently and will be greatly appreciate

usefull content.. good explantion... keep it up .. subscribed..

Can we do it with esp32

Can it be possible to display current and voltage at the same LCD using that same sensor

I have 20A ASC712 Why is it not measuring current 0.9 A? As multimeter showing. I am following the same procedure. 12V DC source and 12 V load with 0.9A

Can someone please explain to me how we are comfortable passing 30a in series through this tiny device with a tiny wire?

yes

excuse me sir, i got 3070-3080 in my sensor output,.. what wrong with my sensor?

If im using nodemcu, where vcc is 3v...is there any change i should make for code? If yes what part should i change?

Can the sensor read negative current? I want to experiment this on motorcycle stator.

can ACS useful for single phase ac motor like drill

Hi，i am using this sensor on my work right, do you have any ideas about the acs712 sensor output doesn't change? Thank you

Hello, can ask how to fix this error? Error: ACS712_05B was not declared in this slope?

I want to see the this lcd value in blynk 2.0 is it possible?

My adc reading >2000, what's the solution??

The code for measuring AC current is not functioning properly.

Please my current sensor is 30A and after doing everything, my sensor is reading zero current when no load is present but it’s reading 2.5 voltage when no load is present as well

Library code in the website is slightly different from your video. It shows enlighter js master. It can be use for AC current measuring or not? Please reply. I want to measure AC CURRENT comes from small transformer (1-30A)range. Please send the solution.

why did you use 1023? When the base is 1024? other tutorials use 1024... Please explain why u used 1023. Thank you for video :) vOut = (voltageSensorVal / 1024) * vCC; // convert the value to the real voltage on the analog pin

the library "ACS712" for the AC current is not showing up on github

hi can you write code for solar monitoring 80 amp input 150 volt input i read on mobile by blynk

Hello..i already follow your step but my reading show 0.00 A. Im using 20A and already change to the 20 A formula but still get 0.00 A..any idea? Thank you

Can't we use any other than A0?

0.066v, not 0.66v

kalau mau ukur arus DC 0-6A adakah yg perlu diubah sir pada kodingan seperti di video?

acs715_05B error showing please help

iam using acs712 30amp and notstabil measuring, whyyy?
