cent88 Posted August 21, 2012 Report Share Posted August 21, 2012 I'm not familiar with inductor. I need this metal sensor for my project. Unfortunately all info I got from the internet are all about the whole device, which is connected to the buzzer.Any one here has any idea or schematic on how to create inductive loop sensor that can output an analog signal or just high/low signal to micro-controller? :) Quote Link to comment Share on other sites More sharing options...
Hero999 Posted August 21, 2012 Report Share Posted August 21, 2012 There are plenty of schematics available. You need to learn how to use a search engine.https://www.google.co.uk/search?q=metal+detector+schematic&hl=en&client=opera&hs=iMn&rls=en-GB&channel=suggest&prmd=imvns&tbm=isch&tbo=u&source=univ&sa=X&ei=JGkzULTLOcqw0QWaoIDwDg&ved=0CFIQsAQ&biw=1024&bih=608As you're obviously having difficulty with that. My advice would be to buy an inductive proximity sensor which can give an analogue or logic signal to the microcontroller. Again, a search engine is your friend.https://www.google.co.uk/search?client=opera&rls=en-GB&q=inductive+proximity+sensor&sourceid=opera&ie=utf-8&oe=utf-8&channel=suggest Quote Link to comment Share on other sites More sharing options...
