    Hi guys I’m working on a thermometer I already build both the Celsius one and the one with the conversion from Celsius to Fahrenheit and they both work well. There is any way to update the code to have two sensors with two different temperatures. Outside temp and inside temp. I must use two LM35, but do I have to write a code to interface two different ADC0804 or there is other ADC able of handle two different sensors? Any one who can help me? Thank in advance here are; the links. http://www.engineersgarage.com/microcontroller/8051projects/celsius-fahrenheit-scale-thermometer-AT89C51 http://www.engineersgarage.com/microcontroller/8051projects/Celsius-scale-thermometer-AT89C51

     go for ADC0808..

    check this http://www.engineersgarage.com/microcontroller/8051projects/interface-three-input-channels-ADC0808-AT89C51

    you can interface more than one LM35 with ADC0808

    good luck!!
