This is a problem. Pins 0 and 1 are used by Serial.begin(), so move s0 and s1 to some other, unused pins.
I didn't understand your code, hope this can clarify! !
The sensors are individually plugged to a 5v power supply. Just the signal wire goes to Analog's pins
Hello again
If you're getting 0 then 1023 values, an average would be absolutely useless. Does the sensor read exactly 0 when fully submerged in water? If not, you could only read the value if it is greater than 0.
To be honest, I dont quite understand your schematic.
When you would like to do the same thing over and over in code, you would use a for function. For example, instead of doing this:
Serial.print(" Percentuale umidita' vaso 1 ");
Serial.print(" e' : ");
Serial.println(A0);
delay(1000);
Serial.print(" Percentuale umidita' vaso 2 ");
Serial.print(" e' : ");
Serial.println(A1);
delay(1000);
Serial.print(" Percentuale umidita' vaso 3 ");
Serial.print(" e' : ");
Serial.println(A2);
delay(1000);
You can do this:
for (int i=0;i<16;i++){//i less than 16 to go through all 16 channels
Serial.print(" Percentuale umidita' vaso " + String(i) + " e' : ");
Serial.println(readMux(i));
}
So an example (test) code for reading the values would be:
#include "Arduino.h"
#include <light_CD74HC4067.h>
//Mux control pins
#define s0 D2
#define s1 D3
#define s2 D4
#define s3 D5
//Mux in "SIG" pin
#define SIG_pin = A0;
CD74HC4067 mux(s0, s1, s2, s3);
void setup(){
//set mux pins to OUTPUT
pinMode(s0, OUTPUT);
pinMode(s1, OUTPUT);
pinMode(s2, OUTPUT);
pinMode(s3, OUTPUT);
//digitalwrite all the mux pins low
digitalWrite(s0, LOW);
digitalWrite(s1, LOW);
digitalWrite(s2, LOW);
digitalWrite(s3, LOW);
//start the serial port for debugging
Serial.begin(9600);
}
void loop() {
for (int i=0;i<16;i++){//i less than 16 to go through all 16 channels
Serial.print(" Percentuale umidita' vaso " + String(i) + " e' : ");
Serial.print(readMux(i));
Serial.println("; Percentage: " + String(map(readMux(i), 0, 5, 0, 100)) + "%");
}
}
float readMux(int channel){
int controlPin[] = {s0, s1, s2, s3};
int muxChannel[16][4]={
{0,0,0,0}, //channel 0
{1,0,0,0}, //channel 1
{0,1,0,0}, //channel 2
{1,1,0,0}, //channel 3
{0,0,1,0}, //channel 4
{1,0,1,0}, //channel 5
{0,1,1,0}, //channel 6
{1,1,1,0}, //channel 7
{0,0,0,1}, //channel 8
{1,0,0,1}, //channel 9
{0,1,0,1}, //channel 10
{1,1,0,1}, //channel 11
{0,0,1,1}, //channel 12
{1,0,1,1}, //channel 13
{0,1,1,1}, //channel 14
{1,1,1,1} //channel 15
};
//loop through the 4 sig
for(int i = 0; i < 4; i ++){
digitalWrite(controlPin[i], muxChannel[channel][i]);
}
//read the value at the SIG pin
int val = analogRead(SIG_pin);
//return the value
float voltage = (val * 5.0) / 1024.0;
return voltage;
}
Take note that the MUX pins are D2, D3, D4, and D5 as #defined at the beginning of the code. Also, SIG_pin is connected to A0. Notice how the readMux() function is used. This function calculates percentage from voltage:
map(readMux(i), 0, 5, 0, 100)
Hope this helps!

Man i really appreciate your help, but as output of this i receive a message of error.
"'D2' was not declared in this scope" if i swap digital pins, or 0 too, in my case.
About the schematic
I have 15 sensors plugged from A0 to A14.
5 sensor plugged in C0 C2 C5 C9 C15 pins on the multiplexer.
From the mux to the arduino
-
- S0 to D0
-
- S1 to D1
-
- S2 to D2
-
- S3 to D3
- the SIGNAL to A15.
+5v from arduino to the mux.
Gnd + En from the mux to arduino.
All the sensors are plugged to a 5v power supply, only the signal wires goes to the arduino (or to the mux, for the others 5 sensors).
If you're still not understanding please let me know it so i will provide more infos.
Ok, I think I understand your connections now 
.
So, D0 and D1 on the Arduino are used for the serial port. Those pins are better left alone, unless you are tight on pins.
Connect MUX to Arduino:
VCC - +5V
GND - GND
EN - NO CONNECTION
S0 - D2
S1 - D3
S2 - D4
S3 - D5
SIG - A0
Sensors:
VCC - +5V
GND - GND
OUT - pins C0 through C15 of the MUX
NOTE: Do NOT connect any of the sensors to the analog pins of the Arduino, only attach them to the MUX pins C0 - C15.
Did you select the correct Arduino board in the IDE?
If you did select Mega already and it still wont work, exchange the #defines at the top with this:
#define s0 6
#define s1 7
#define s2 1
#define s3 5

The problem is that i have 20 sensors and i wanted all of them running.
I tought taking the most of them onto the arduino board would be better then stick to the mux, considering the noise of the signal that this would generate.
What's your suggestion about this?
I might just use 16 of them, i changed idea because i realized this is starting to be too complicated for me.
I was thinking about just skip the mux part, take the print of all the Analogs, remove the 0 and the 1023 from the equation (so this will fix the "faulty" side of the game) and show a percentage of the averaged result.
This should sound easier doesn't it?

Ah, I forgot you wanted to do 20 sensors. So, I would attach 15 of them to the Mega's analog pins like you already have I think, and I would hookup the other 5 to the mux.
Wire 5 of the sensors to the first 5 C# pins of the MUX.

Try auto formatting your code.
Did you notice the
void loop() {{
for (int i=0;i<5;i++){//i less than 16 to go through all 16 channels
Ser
Each { must have a } I bet if you count { and } the number is not equal.
You were right, but that didn't change much
"Serial.print(readMux(i));" gives "'readMux' was not declared in this scope"
did you happen post the changed code in a new post?
Afterall, if you made that error, you made others. One error at a time.
