Wheel speed sensors- data interfacing

[bobdxcool]

Hello

Could anyone suggest any wheel speed sensor circuit circuit, so that the output of the sensors (speed ) is fed to a micro controller.

Or is it possible to take the reading from a digital speedometer? Is there any circuit for this?

Which micro controller should I use?

at89s51 or arduino?
