Multiple I2C sensors and libraries using Arduino(s) on a Water Tank ( Wireless )

Abdulaziz14:
So, the code is good ?

it looks good.

Abdulaziz14:
Could you explain me the step 5 ? is this a systematic way to read values ?

I use

    byte hi = x.read();
    byte lo = x.read();
    int res = hi * 256 + lo;

but shift operator is faster
