Hi every body .
i'm working now on the home weather project using the LM35 temperature sensor.
The goal of my project is the take readings from the sensor and displaying it on the computer recipient through the parallel port, thus a program is provided here to display the readings,which is written by c#.net programming language.
achieving this issue , other components included to our circuit such operational amplifier LM358 and ADC0804 convertor.
My question here is : what is the benefit of the opreational ampilifer in our circuit ?
this is the circuit diagram of my project :
**broken link removed**
