connecting NH3 and CO sensors to PIC16F877A

[skimask]

Hi,i want to connect ME3-NH3 and ME3-CO gas sensors to PIC16F877A,but their datasheets are not complete and not clear

Looks complete enough to me... Current ouput = gas concentration...

i have sent a mail to company and they send me some more information but i don't think it's enough

Ya...that'll work... NOT! Maybe if you were buying 1,000 of them.

could you tell me how can i connect them to PIC16F877A(hardware) and how can i write the code?

You can connect the output from the sensor to the '877A in the usual way and use the A/D inputs.
You can also write the code using a keyboard and a PC.

I use picbasic pro.

How often?
