hatandm Posted May 13, 2007 Report Share Posted May 13, 2007 For a simple smoke detector you could use an MC14467 ic. Look at page five in this datasheet and it gives you a pretty simple circuit schematic; just a few external components and a piezo alarm. (The chip costs like $1.50 at digikey.com)Datasheet:http://rocky.digikey.com/WebLib/Motorola/Web%20Data/MC14467-1.pdf Quote Link to comment Share on other sites More sharing options...
