Hi Hello Everybody today I am going to show you that how to make Temperature monitor project using LM35 sensor and Pic microcontroller.
Why we chose PIC16F877A not 8051 Microcontroller?
The answer is simple in this project we are using LM35 sensor which is analog sensor here we need another ic (Analog to Digital) to convert the sensor analog reading in to digital so If you are going to chose 8051 microcontroller for this project you must attach another A2D ic because 8051
have no bulletin A2d converter but Pic microcontroller have so that’s why we select PIC16F877A instead of 8051 because it’s easy, cheap and simple.
This is Temperature sensor which you can get easily from the market with low price The LM35 pin out is so simple the first pin is for input power maximum 5v Dc and the Middle pin is for Analog input and the third pin is for Ground
10mV ===> 1C
20mV ======> 2C
370mV ====> 37.0C and so on……
Software and Other Tools :
First you need to install the Proteus vsm on your computer the good news is that you people can download Proteus Setup free from our blog and the second one is PIC-C compiler where you people can compile the C-code and will get the Hex file.
you just need Pickit 2 Burner just put ic and Burn program on it and enjoy …
i upload the Zip file to Mediafire click to Download
