I wonder how the sensor woul behave if the curent reaches 35 or 40 amps.
I think the analog pin is going to get more than 5 volts....
Any one any experience ....??
The lowest sensitivity part outputs 0.185V/A, so at 30A that would be 5.55V.
At the same time, output won't exceed VCC, or 5V.

The sensor can't output more than it's own supply.
If you supply it from Arduino's 5volt pin, 5volt is the theoretical limit of the output.
Practically, you won't get more than 4.75volt.
That means that a 30A sensor might measure a bit more (~33.75A) before it reaches the limit.
