Guest Posted May 24, 2004 Report Share Posted May 24, 2004 Here i have made a digital thermometer using LM 35. Check out the circuit for digital voltmeter on this site and also the discussion on it.LM35 gives the proportionate voltage which will be measured be the voltmeter. Use the voltmeter for 2V full scale reading. I will post the circuit diagram tomorrow. Quote Link to comment Share on other sites More sharing options...
