You have to use A/D converter of PIC and implement a conversion table on code based on sensor chart.
for displaying on the lcd screen, i think you have an in-built controller on lcd.
For code you can search in piclist forum at www.piclist.com

look at AN684 application note on microship's site.
On this app. note the temperature sensing with thermocuples is revealed.
The theory is the same for your application. This can help you.

simple...
the adc just measures the analogue voltage present on an ADC channel (in the datasheet this is given as AN0, AN1, this simple means analogue channel 0, 1 etc.), and then converts it to a 10 bit value. The 16F877 has a 10 bit ADC, this means a maximum of 2^10 range, or 1024 bits for a full scale value.
In other words when 5 volts (same as the ADC reference voltage) is given to an ADC channel, the equivalent word value is 1024.
Thus the calculation for conversion is as follows.
ADC Word= (Channel VoltageX1024)/5
when I volt is given we get (1024X1)/5 = 51
Similarly this value can be converted back to voltage, during display..

The complete code ,including LCD interface and the temperature sensor interface with microcontroller can be found here on the following website in different post.

hi
u can test using proteus software.
and it has built in LM35 sensor.
this software can download this side.
