Speedometer Sensor

[atheos]

Dear electronics-lab community,


I have decided to build one of the many speedometers (for my motorcycle) I have found around in the internet.Unfortunately all of the projects dont include the sensor or even imply one.I have searched through the internet (and electronics-lab) for such a kind of sensor.

I have found magnet sensors and  hall effect that apply to similar low speed/revolution projects.I havent found a project that certifies that any of the above stated sensors would be reliable or even work at the speed of 200km/h.

This is where the community steps in.Has anyone actually had any experience  with the kind of sensor I am looking?

P.S Thank you in advance

How is the original speedo arranged on your bike?

It is a regular analog speedometer connected via a cable (mechanical that is) fitted on the front fork

You could attach a small tacho to the cable and convert the output to suit the circuit. Or you could use a small inductive sensor to count the rpm
