    Digital Thermostat using 8051 Microcontroller

    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 :)

    Re: Digital Thermostat using 8051 Microcontroller

    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...sor-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.
