Sample Code1

Library installation

void setup()

{

Serial.begin(9600);//Set Baud Rate to 9600 bps

}

void loop()

{

int val;

int dat;

val=analogRead(0);//Connect LM35 on Analog 0

dat=(500 * val) /1024;;

Serial.print("Temp:"); //Display the temperature on Serial monitor

Serial.print(dat);

Serial.println("C");

delay(500);

}

Sample Code 2

float tempC;

int reading;

int tempPin = 0;

void setup()

{

Serial.begin(9600);

analogReference(INTERNAL);

}

void loop()

{

reading = analogRead(tempPin);

tempC = reading / 9.31;
