Hi guys,
I am a final year automobile engineering student. I have to make a speed sensor for my project. I am thinking of making a magnetic pickup type sensor. I came across an article abt making this sensor using the windings of a relay. So I think, I am good upto the sensor. Can someone tell me how to process the sine wave output(i.e. converting to square wave and then processing). The objective is to get the speed of the output shaft of a gear box and energize a solenoid when the required speed is attained. I dont know much abt electronics. But I ve a lot interest. So please help me. Thanks![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
