Sorry about that, the sensor tolerance ±0.012 uA/ppm. Aside from the calibration procedure, the circuit I have made keeps failing. I connected this to a wall outlet, so 120V the resistor i am using is 10K so 16.6KOhms +-1%. As for the sensor I just disconnected this from the 5V pin and itis reading the following values

No idea what's going on here. Sorry to say but I'm pretty lost.

 

Wait, nevermind the sensor I think is ok since it goes from 0-100 ppm and it is reading 13ppm. So, for now, it is OK. Thank you a lot. Im going to continue on my quest and finish connecting this to the Arduino without short circuiting which is happening a lot.

 

I connected this to a wall outlet...

The wall outlet provides AC, not the DC signal that would be expected.

 

DC signal for what? Should I change it up?

I assumed you were trying to simulate the current produced by the sensor? That would be a purely DC signal. A battery would work.

 

Ok, thank you very much. I even learned a lot from this.
