Hi all;
I'm fighting with ASM-010 sensor, so i'm trying to make some code to measure the current through this sensor and Im getting some problems.
The problem I have is that i dont know how to read an AC value with my arduino. I have tried to sample Volts signal but I failed.
I have read a lot from this web:
http://openenergymonitor.org/emon/buildingblocks/ct-sensors-interface
and I know im close to achieve my aim. Is there anybody who has made some code for arduino or something to control this sensor?
Here is the datasheet:

Thanks a lot
Re: ASM-010
That looks to me like a standard ring-type current transformer. If so, you treat it exactly like our "standard" YHDC split-core current transformer, and you can use the sketch that's linked at the bottom of the page you quote - just above the start of the comments.
The sketch uses the emonLib library that you can download from Github. The library handles reading the input and calculating the average current.
