what about toyota corolla car's sensors?

my car is toyota corolla 2000
I want to convert my current dashboard from analog to digital one.
What is the type of the outputs of the car's sensors(speedometer sensor,temperature meter sensor and fuel meter sensor)?
Is it voltage,current,resistance or frequency?
How can I know the location of these sensors in the car??

Why don' t you look in the service manual ?

yes I did , thank you.
The Toyota will have an OBD port hidden somewhere. The simplest thing to do is to read that, and process the data from there to your display.
