interface sht11 sensor via pic16f876 to display temperature

[wmipdivarathne]

:?: im designing a wireless sensor network which measures temperature at a remote place. And im using sht11 sensor with pic 18f876 microcontroller. Can anybody help me to get the source code in microC and the circuit diagram.

yeah this i viewed before i do have all the data sheets but i need to have a simple circuit setup of connecting pic 16f876 to this sht11 sensor and the program code in microC to program the pic.
anyway thanx for your post...:!:

Why use SHT11? If it's only for temperature measurement, it is a financial overkill.
Farnell price for SHT11 is 23.79 €

I think that it is better to use DS18B20
Farnell price for DS18B20 is 5.32 €

And DS18B20 is much easier to interface (by means of software libraries) than SHT11

explain the program for the transmitter

unsigned short
i, ch;
char s1[] = "Adhoc";
void main() {
INTCON.GIE = 0; // Disable interrupts
Man_Send_Config(&PORTB,5); // Initialize manchester sender
while (1)
{
Man_Send(0x0B); // Send start marker
Delay_ms(100); // Wait for a while
ch = s1[0];
i = 0;
while (ch != 0) // string ends with zero
{
Man_Send(ch); // Send char
Delay_ms(90);
i++;
ch = s1;
}
Man_Send(0x0E); // Send end marker
Delay_ms(1000);
}
}

this is the microc coding for a transmitter using pic16f877.
it's using the manchester coding.
i need explanation of what's happening exactly in this program. please give full explanation.
