C

I have a Wireless Sensor Network (WSN),that composed from coordinator and 3 end nodes with Zigbee technology ,connected the coordinator to the PC by serial port and opened it with C#. the coordinator collect the data (temperature reading from temperature sensor) from the 3 end nodes and monitor it on c# design and also save it in DB , Now i want to compare the data i get from the sensor with a set point i set it in the coordinator , if the data read greater than the set point the fan on PORTA.f0=1 else PORTA.f0=0.

float temp_res=0;
float temp;
const unsigned short VREF = 4.75;
char address;
char txt[4];
char FanStatus=0x66;     // fals(f)=0x66

void main() {
ANSEL = 0x02;               //Configure AN1 pin as analog
TRISA = 0x02;               //Configure AN1 pin as input
ANSEL = 0X00;              //configure AN0 pin as digital
TRISA = 0X00;               //configure AN0 pin as an output pin
TRISB  = 0;                 //configure POrt B as an output port
PORTB=0;

        ADC_Init();                               //Initialize the ADC
        UART1_Init(9600);                         //Initialize the UART with 9600Kbps Baud Rate
        Delay_ms(100);                           // Wait for UART module to stabilize
       PORTA.f0 = 0;                            // FAN initially OFF
 while(1){    temp_res = ADC_Get_Sample(1);      //Get temp readings from ADC module
              temp = (temp_res * VREF)/10.240;
              floatToStr(temp, txt);

           if (UART1_Tx_Idle()==1)                 // end if idel
              {
                 UART1_Write_Text("z");
                 UART1_Write(FanStatus);
                 UART1_Write_Text(txt);
                 UART1_Write_Text("end");
               }
               
            if (UART1_Data_Ready()==1)              //If data is received
               { address=UART1_Read();              // read the address
                  if(address==(0x7A))               //if the address=z
                     {
                PORTA.f0 = !PORTA.f0 ;        // switch FAN ON/OFF
                if(PORTA.f0==1)
                      {
                         FanStatus=0x74;  //true
                      }
                else if (PORTA.f0==0)
                      {
                          FanStatus=0x66;   //fals
                      }
                     }
               }                                   // end if ready

          }                                       // end while
