Hi ravitejashivuni,

How can I calculate speed if my sensor give me voltage/meter.

So you get a voltage dependend on a distance?

To get speed you need to calculate "(distance(now) - distance(previous)) / (time interval)" - use a shift register…

Here I am getting Voltage data from speedometer

Does your "speedometer" output "speed" - or should it be called "distancometer" instead? 😄

Please be clear in your explanations. Attaching a data sheet always helps for such type of questions…

To convert voltage value to the correct Speed first you should know the voltage out put range of the meter(you will get that in data sheet of the meter),For ex:0 to 5 V corresponds to 0 to 100RPM.Then based on this value you can convert voltage to speed.

Or maybe a Metermeter!
