hi,plz tell me that how can i configure lm 35 with at89c2051 and plz send the necessary links ,from where i can study the circuit diagram.
 

The AT89C2051 has analog comparator but it’s really not enough to practically measure temperature with the LM35 ..
You need A/D converter, for example ADC0804 (see link below) or PCF8591 ..

Another option is to change the temperature sensor from LM35 to DS1820 which is reasonably easy to interface with any microcontroller .. see picture below ..

for the lm35 just you have to connect it to to adc.
10mV/C. it is simple but you must have a good pcb design.
The DS1820 is immune to the pcb design.
