TUTORIAL: How to use the ACS712 hall effect current sensor module with Arduino! (to measure current)

My website link for downloads (if any are present), etc:

Just some ramblings on how to measure current into the Arduino.

Wow! The quality is terrible! I'll redo this video soon.

[AntonyCartwright]

I'll explain how to measure AC current if I get enough requests! :-)

Hello sir,
I have a doubt regarding the use of acs712 sensor. My doubt such that, is it possible to measure current using this sensor in 3 phase spindle motor?

[farhanahossain]

Can u tell me why am I getting 1023 reading without load but however when I measured voltage for Vout pin of the current sensor it shows 2.3V

[pranav]

Is there a way i can use a sensor to detect current through a certain wire and then switch off a motor based on that input.

[acqurius-gxlr]

is it possible to measure ac current of signal with frequence of 1kHz with ACS712?

[kaioid]

i am trying to mesure the curent of a 12v DC motor using Acs712 and arduino nano. i used the same diagram and code but all i get is some wrong negative values. can anybody tell why ?

my term project is about reading AC-Current can you help me with that

[pedrocastillo]

How many volts can I put in ACS712 because I need to work with 3 different voltages 120VAC, 26VAC, 72VDC. Thank you in advance

hello sir !
i am measuring power factor through ATmega8 micro controller..
i used "zero cross detection" technique to find power factor..
but the output wave of this "ACS712" sensor does not touch zero (ground level),
it give me output wave form from "2.5" to "5".
i want to get its output symetrical across zero... what i need to do... ?
plz give me sugeestion to solve this problem..?

[zawirzahid]

sir what is the max voltsupply for the acs712 thatu use?. what type of acs712 that u used? it is 5/20/30A?

[patriciabrooks]

0.066 was stated as typical ... not to be taken as absolute.

[tablatronix]

These seem very susceptible to input voltage, so a stable 5v with no drops, I noticed. I also get wierd results depending on grounding and high or low side measurments, not sure if it has to be low side or not.

[christopherhemmings]

you need to adjust the 0.066 as it's obviously not the correct value as your. current does not line up

[mayankshri]

I am using ACS750 Hall effect current sensor and Arduino Mega. When I try to get the readingsinitially coming to Analog Pin, readings are too vague (values are changing continuosly, i.e. sometimes 540 and on the other instant 570, 480 and so on). I am not able to stablise the readings, kindly help

how to convert courant sensor(ACS712) value rawvalue to amper, in my circuit, i have capacity and a LED

[prashantthapliyal]

How to check if the module is not faulty?

[pqlsxlv]

hey Antony I'm a subscriber (if you didn't know I'm Jake you know right don't ya?) + Kian's messing with anvils 😂

[StayBased_]

Why did you use 0.066 to divide the voltage by?

[willentinejerry]

hey it can measure power? using P=I^2 R
