Description

Simple 3 Digit Temperature Meter





This project is a simple temperature meter using LM35 analog sensor connected to PIC microcontroller PIC16F676. The temprature is displayed on 3 digit 7-segment display. Project code is written in C language for CSS compiler for PIC. Here are few things that you can expect to learn from this project:

1. Using Analog port of PIC Microcontroller
2. Interfacing LM35 temperature sensor
3. Interfacing 7-segment display
4. Multiplexing multiple 7-segment display

Simple yet so much to learn in this project. If you are a starting to learn microcontrollers then this is your project. The download package also includes a proteus simulation so you can modify and test this code before building the actual hardware.

I want to thank Rakesh Suthar for submitting this project. I hope to see more learning oriented project from him.

Download Package Content:
  • main.c : Project C code
  • main.hex : Hex file
  • schematic.PDF : Schematic file
  • lm35-temp-meter.pdsprj : Proteus simulation Project file


If you have any questions or queries on this project feel free to ask in forum.

The site editor may have removed the 0 from \0.Actually it should not be needed, sochar *phone_no[3 ]={"1234567890" ," 9087654321" ,"76676667676"}; //array of pointers should work.
