Honeywell Speed Sensors with Arduino

Hello All,

I want to code in Arduino Mega for 2 Honeywell Speed Sensor SNG series for calculating average speed of the vehicle but I am unable to get it.
Does anybody has any idea regarding it or can I get some sample code for reference basis, it will be helpful for me.

I am attaching pdf for the same.

Thanking You in Prior.

It's just a regular quadrature encoder. Use any library/function (for example Arduino Playground - RotaryEncoders) and just multiple "clicks" by corresponding length.
