Hi,i want to connect ME3-NH3 and ME3-CO gas sensors to PIC16F877A,but their datasheets are not complete and not clear, i have sent a mail to company and they send me some more information but i don't think it's enough,could you tell me how can i connect them to PIC16F877A(hardware) and how can i write the code?
I use picbasic pro.

you can see their datasheets in this website:
