Need help in interfacing of DS 1820 with 8051

Hi all

how can i interface DS1820 temperature sensor with 89s52 uC. So that it can display temp on LCD.

thanks in advance

  • The datasheet for the DS1820 tells what interface it has. It will tell what size of pull-up you need and the timing for the protocol.

    The datasheet for your display will give the needed information how it should interface to the processor.

    Google will find you sample code for the Dallas one-wire interface. Most probably, you will be able to find sample code for your display too.

    Integrate and add a bit of glue code in between, that picks up the temperature values and formats them into a string and displays that string.

    How much have you done already?
