You also need to change the LCD connection as you have connected RB0->D7 RB1->D6 and so on ...

Which is a reverse order.

Also you have connected the PGD and PGM pins which are used to transfer program to PIC16F877A. It is recommended that they are left free.

Hello,

I have attached a proteus simulation project that will show humidity and temperature on the LCD module. Please check and inform.
