Hello Folks.....


i'm working on a digital speedometer....


i jus want to know about speed sensors......all about them.....any websites on them ?....also any good cheap available such sensors.....i tried googling.....but thats jus toooooooo much info......
 
even a simple switch can be used as a speed sensor, count the pulse for a given time the result is proportional to the speed
 

Hi there!

You need to narrow your terms--both on Google and here. "Speed sensor" could mean a lot of different things, and neither a search engine nor people on a forum will want to guess at what you mean.

What do you want to measure the speed of? A car? A robot wheel? A data transfer? A subatomic particle? Try to describe the actual application and the precise problem you're trying to solve.

Post more information, and good luck!

For a signal source, you need to use the drive shaft or the speedo cable coming out of the tranny. For resolution, the pick up will have to output several pulses per driveshaft revolution. And then you'll need to figure some way to calibrate the ditital speedo - relating pulses/sec to actual speed.
 
Search this Electro Tech forum for speedometer and tachometer. You will get some good info and an intro to microcontrollers.
 
Guys stop responding to this guy...he's obviously either a complete moron or a fake poster...look at his other posts.

If you can't be bothered to make the slightest effort to communicate properly, why should anyone bother answering?.

I can only hope that this is a joke or that you aren't ACTUALLY in 3-4th year engineering. That is the WORST grammar I have ever seen on the internet...not even a translator would be that bad.

Actually, the grammar does not look too bad to me.

The spelling and puctuation is a different matter ...
