Analog to Digital Circuit Design

[itachi012587]

Hello everyone.
I am looking for the circuit of LM35 temperature sensor interfacing to a microcontroller, by the way I am using PIC16F877A. And also, a sample code in assembly where show the convertion of analog signal into digital.
Thank you.

i interfaced the LM35 with Pic 16F877 but i did programing in C langauge is it helpful to u

Thank you for your reply.

If you don't mind may I have a copy, what I mean the schematic diagram and the program code even though it is written in C. Because I thought that is really help me a lot.

Thank you.
Best regards.

hi
if ur using To92 pakagae i.e transister like, first pin is vcc 2nd is output,3rd is ground,all u need to do is to take 2nd pin to ur controller input pin, i did it but i used a unity follower buffer between the out put pin of sensor and input pin of cotnroller, another ciruit is can be seen at following link
