Noise on CT sensor Input

Submitted by Wesleyphoenix on Mon, 12/10/2015 - 23:30

I'm doing this with the Arduino Mega and the display shows values even without devices connected to the sensor.

Please, someone help me.

It's probably just noise.  Have a read of http://openenergymonitor.org/emon/node/10111 and see if anything there helps.  Pay particular attention to how you power your Arduino, and make sure you have good solid grounds everywhere.
