ACS758 Arduino Current Sensor Tutorial

Results 1 to 9 of 9. That part is not a problem. The problem I am seeing is the same problem I read about in this thread Just so I could see some real current other then a light bulb I am using a watt hair dryer which I am attempting to read how much current it is using. When I turn it on the current follows the AC and my reading goes from This is equal to datasheer.

The math seems right so far. What I am having a problem with is as I said the same as the other person. The current is rising and falling with the AC so I am not getting a steady reading.

I have used the MAX command to get this far but I just can’t seen to figure out how to get or keep track of a reading that is not fluctuating with the wave of the AC. I didn’t see that the person who was trying to do the same thing with the and ever came up with a solution. As always any help would be appreciated. Join Date Dec Posts 1, Assuming a more or less pure sinewave, current follows the same pattern, However, for anything other than a pure resistive load, voltage and current will be out of phase and you may or may not have a sinewave.


You have to take many instantaneous measurements of dagasheet voltage and current and average them over time to get true power. You had me at thus Originally Posted by dhouston. With a purely resistive load, you should be able to establish the peak through timing.

At 60Hz it will occur 4. It will also change with dahasheet loads which most electronic gear presents. The only way to do this accurately is with many nearly simultaneous samples of current and averaging over time.

Digital power meters sample voltage and current several thousand times per second. Your PAUSE means you are only sampling a few times datawheet second and so are unlikely to get the peak.

In a perfect world Trial and error and possible solution I’ve been trying allot of different approaches to my problem not wanting to give up and certainly not going to wait for someone to drop code in my lap.

I came up with this routine that seems to be pretty stable. Allegro Support Just got off the phone with Allegro support who called me back after I emailed them just to confirm I wasn’t going crazy and I didn’t hook up something incorrectly and sure enough the Vout on the Daatasheet will produce a acs7544 wave proportionate to the current being used. So I simplified the heck out of my prorgam and just have it loop through as quickly as possible keeping track of the MAX and displaying that at every count.


I will experiment with that and watch it closely. I need to incorporate this into a circuit with another sensor, pressure transducer, hopefully I can run that pressure transducer and 2 of these Allegro ACS’s all on my 16F He also told me that the have an 8 pin version that for my application will read up to 30 amps and I should really be looking at that.

He also told me the xcs754 sheet for the ACS has some peek voltage circuit examples which I am going to look at right now. Again if anyones worked with one of these current sensor and has any good code examples they found worked I would not mind taking a peek at that.
