Hi all, I'm new on this field, and if someone can help me to simulate Digital thermostat on Proteus with LM35 sensor, and write code in assembly language, thank you :)

LM35 gives an analog output. It outputs 10mV per degree Celsius. You will need an ADC (analog to digital converter) to interface the LM35 to the microcontroller. Few 8051 microcontrollers I know of have an on-chip ADC. So, you may need to use an external ADC such as 0804.

For interfacing LM35 with 89S52 using ADC0804 check here:
http://www.eprlabs.com/2011/11/89s52-based-temperature-sensor-using-adc/

If LM35 is not a strict requirement, you can use a sensor like DS18S20 to interface directly with the microcontroller without the need to use an ADC.

Hope this helps.
Tahmid.
