 automotive electronic project Looking for ideas on a curcuit that I can monitor the output of a 5 volt DC sensor. It has to be adjustable, when the sensor reads a set voltage or higher it turns on a 12 volt automotive relay. Anny ideas would be greatly appreciated. | |

| I'd use the LM311 myself as it's output can directly drive small relay. Some good sites with information on comparators. http://www.play-hookey.com/analog/comparators.html http://home.cogeco.ca/~rpaisley4/Comparators.html http://www.google.com/search?num=100...or&btnG=Search
