Hi all. i am currently trying to build a energy monitor station with an arduino and labview. I am using a CT clamp sensor to measure roughly 1.3 amps. Because this is so small the sensor outputs an AC signal in Mv which the arduino cant read. So i built a non inverting Op amp circuit to amplify the signal of my current transducer. The signal is now approximately 2.40v AC. When i connect this to the input pin on my arduino i cannnot seem to get a reading at all. Any help greatly appreciated as i am out of ideas and not very familiar with with the whole operation

 

Use ADC to take reading of ac voltage.

 

I am using an arduino and interfacing this with labview. But when i have my 2.40v AC connecting to my arduino i do not get a reading on labview????

 

Oops, you did say you use labview.

Try using Arduino IDE Serial Monitor. It is pretty easy to use. See if that works.

 

I have my adruino connected to my PC via usb so no problem there. I cannot seem to read the AC voltage coming in
