Error while reading analog input through arduino to labview.

I didnt connect sensor to analog pin of arduino  but still its showing some analog voltage read by arduino in labview.

That is normal for any analog input (not just Arduino).

P.S. I recommend that you switch to LINX since LIFA is no longer supported (for the last couple years).

I am able to read exact analog voltage if single sensor is connected.But the problem is while connecting multiple sensors, the analog voltage on one pin is copied  to another pin even if i didn't disturb another pin.

You'll need to be more specific about what exactly you have hooked (the

sensors) and to which pins as well as which pins you are reading and what

values you are getting on those pins.

Thank you for your valuable suggestion, telling to switch over to LINX.Just now i tried with LINX i got best results with out errors.
