stuee Posted January 13, 2010 Report Share Posted January 13, 2010 Im installing a thermo fan in my car but want to use the existing temp sensor to my temp gauge for the sensor. I can find out the resistance for it but something i can vary too would be good. If anyone knows a simple circuit / diagram i would appreciate it.thanks Quote Link to comment Share on other sites More sharing options...
Hero999 Posted January 13, 2010 Report Share Posted January 13, 2010 A simple comparator circuit will do, I'd recommend the LM311, read the following :http://home.cogeco.ca/~rpaisley4/Comparators.htmlhttp://www.silicontronics.com/index.php?action=ezportal;sa=page;p=17 Quote Link to comment Share on other sites More sharing options...
