Hello, I just wanna know if it's possible to build an energy monitor like this one: http://openenergymonitor.org/emon/buildingblocks/how-to-build-an-arduino-energy-monitor-measuring-current-only but not using the CT sensor used in that project, i want to use this one (cheaper): http://store.ecof…

20A CT Sensor

Thanks a lot!
I tried to calculate the proper burden resistor but i need to know the turns of the CT. How is possible to find it out?
