SHT11 Humidity Sensor I2C Code for MplabX problem

[Yamber]

Hi all,
I'm very new in Programming. I would like to realize a project using an Lm032 LCD, A SHT11 Humidity Sensor, PIC18f2620 (mplab, Proteus). I went through the device datasheet and I wrote the following code. But the result is terrible. I need assistance please.
Tnx in advance.

//#include <stdio.h>
//#include <stdlib.h>
#include "HUMIDITY.h"
#include <delays.h>


void DelayXLCD (void);
void Delay18ForTCY (void);
void DelayPORXLCD (void);
void init_XLCD (void);

char humidity = 0;
int temperature = 0;

void delay_1s (void);
//void delay_s (void);


int main (void){
    char data ;
    //TRISC = 0xFF;
    OSCCON = 0x76;
    init_XLCD();

   putrsXLCD ("SYSTEM READY");
    __delay_ms(60);
    WriteCmdXLCD(0x01);
    OpenI2C (MASTER, SLEW_OFF);
    SSPADD = 45;
    /***********************/
    IdleI2C ();
    StartI2C ();

   while (SSPCON2bits.SEN);
   __delay_ms(90);
    while(1){

        RestartI2C ();
        IdleI2C();
        WriteI2C (0x03);
        IdleI2C ();
        temperature = ReadI2C ();
        IdleI2C ();
        AckI2C ();
        __delay_ms(1);

        WriteI2C (0x05);
        IdleI2C();
        humidity = ReadI2C();
        IdleI2C();
        NotAckI2C ();
        __delay_ms(1);
        StopI2C ();

       // LATB = ReadI2C ();
        putrsXLCD (" Temp= ");
        putrsXLCD (humidity);
        putrsXLCD ("    ");


//        SetDDRamAddr (0x40);
//        putrsXLCD("RH =");
//        putrsXLCD(humidity);
//        putrsXLCD("    ");

    }
 }

void delay_s (void){
    int i;
    for (i =0; i < 20; i++)
        __delay_ms(50);

  }
void init_XLCD (void) {
    OSCCON = 0x76;
    OpenXLCD(FOUR_BIT & LINES_5X7);
    while (BusyXLCD());
    WriteCmdXLCD(0x06); //Move right don't shift
    WriteCmdXLCD(0x0C); //Display On
    WriteCmdXLCD(CURSOR_OFF);
    WriteCmdXLCD(0x01); // Clear Screen

}


void DelayXLCD (void){
    Delay1KTCYx (20);
}
void DelayFor18TCY( void ){
    Delay10TCYx(20);
}
void DelayPORXLCD (void){
     Delay1KTCYx (60);
}
