Error in compiling code

Hi everyone, I hope you are all well, I'm not so much, I do not speak much English so I counted on the help of google translator to write.
I am facing serious problems with my source code while compiling in the Arduino IDE, it gives the error in the following passage: sensor = analogRead (A5); And says: sensor not declared in this scope.

I ask for your help. grateful.

here is the code:
int bomba = 8;

#define SP 95

void setup() {
Serial.begin(9600);
pinMode (A5, INPUT);
pinMode (8, OUTPUT);
// put your setup code here, to run once:

}

void loop(){

int sensor = analogRead(A5);

if (sensor > SP){
digitalWrite (bomba, HIGH);
// put your main code here, to run repeatedly:
}
else{
digitalWrite (bomba, LOW);
}
Serial.print("valor do sensor de humidade do solo: ");
Serial.println(sensor);
delay(1000);

}

Serial.print("valor do sensor de humidade do solo: ");
Serial.println(sensor);
delay(1000);

}

it compiled fine for me, but I got a warning about #define SP... so in arduino it is already defined

try:

#define SP_VALUE 95

int bomba = 8;

void setup() {
  Serial.begin(9600);
  pinMode (A5, INPUT);
  pinMode (8, OUTPUT);
}

void loop()
{
  int sensor = analogRead(A5);
  if (sensor > SP_VALUE) 
  {
    digitalWrite (bomba, HIGH);
    // put your main code here, to run repeatedly:
  }
  else 
  {
    digitalWrite (bomba, LOW);
  }
  Serial.print("valor do sensor de humidade do solo: ");
  Serial.println(sensor);
  delay(1000);
}

Ohh worked, thank you very much.
