I think, your RS pin from lcd1 is connected to a floating pin on pic (RE0) and your code is putting RB0 to ground.
are you supposed to connect RS to RB0 ?
I don't know basic pro, I use C. Make sure you're initialising lcd properly in your code (with specified minimum delays).
I've simulated same lcd with 8051 and (...)

You have to use A/D converter of pic and implement a conversion table on code based on sensor chart.
for displaying on the lcd screen, i think you have an in-built controller on lcd.
For code you can search in piclist forum at
