Introduction: ARDUINO TEMPERATURE SENSOR LM35

By

Now make your own temperature sensor by Arduino and LM35 Sensor
You required following parts
1-ARDUINO BOARD ANY VERSION
2-LM35 TEMPERATURE SENSOR
3-USB CABLE
4-COMPUTER WITH ARDUINO SOFTWERE

MAKE THE CONNECTION AS SHOWN IN IMAGE AND UPLOAD THE FOLLOWING CODE ON ARDUINO BOARD.




int val;
int tempPin = 1;

void setup()
{
Serial.begin(9600);
}
void loop()
{
val = analogRead(tempPin);
float mv = ( val/1024.0)*5000;
float cel = mv/10;
float farh = (cel*9)/5 + 32;

Serial.print("TEMPRATURE = ");
Serial.print(cel);
Serial.print("*C");
Serial.println();
delay(1000);

/* uncomment this to get temperature in farenhite
Serial.print("TEMPRATURE = ");
Serial.print(farh);
Serial.print("*F");
Serial.println();


*/
}








NOW SEE THE SERIAL MONITOR IN THE ARDUINO SOFTWERE ,
ITS DONE.
