As most of all already know that AT89s52 is a microcontroller from microcontroller family and it has no any feature of internally built analog to digital converter and since LM35 being an anlog sensor, we will require a suitable means of converting the analog signal obtained from LM35 to a discrete time signal.

So, by now you must have already known that interfacing LM35 requires knowledge of interfacing analog to digital converter with AT89s If you donot have knowledge on interfacing analog to digital converter with AT89s52, you are recommended to read this post Interfacing ADC with AT89s52 first.

The pin layout on LM35 is shown below in fig a. The output of this temperature sensor is analog in nature and need to be converted to digital form and this is done with the aid of analog to digital converter. In this case we will be using ADC as an converter. The schematic for interfacing LM35 with AT89s52 is shown in figure b. The reference voltage for conversion of analog output from LM35 to digital form is 2. The procedure used to program to convert the analog signal to digital signal is the same which was used in previous post Interfacing ADC with AT89s After programming for conversion you need to write a code to convert the obtained digital value into decimal representation form which can be displayed in LCD.
