About sensors and microcontroller PIC18F4550

Hey

I have a question in my course work and would like to ask for your help. I've made a homemade moisture sensor with two galvanized nails placed at a distance from one another and i'm going to use a NTC10K temperature sensor. I wonder how can I read the signal output of the two sensors. The humidity sensor is connected to RA0 pin PIC18F4550 and the temperature in the same microcontroller RA4.

Thanks, guys.
