Analog Temperature reading using Analog Temperature senor and Arduino Nano development board.

Requirement

1x Arduino Nano 3.0
1x LM35 temperature sensor
Breadboard and wires

Below connection diagram would help to connect Analog Temperature senor with Arduino Nano development board.

Board connections.Development Board Setup.

Copy sample code to analysis analog temperature.

// Setup by Sourabhh Sethii.
//TMP36 Pin Variables

int sensorPin = 0; //the analog pin the TMP36’s Vout (sense) pin is connected to the resolution is 10 mV / degree centigrade with a 500 mV offset to allow for negative temperatures.

/*
* setup() — this function runs once when you turn your Arduino on
* We initialize the serial connection with the computer
*/
void setup()
{
Serial.begin(9600); //Start the serial connection with the computer
//to view the result open the serial monitor
}

void loop() // run over and over again
{
//getting the voltage reading from the temperature sensor
int reading = analogRead(sensorPin);

// converting that reading to voltage, for 3.3v arduino use 3.3
float voltage = reading * 5.0;
voltage /= 1024.0;

// print out the voltage
Serial.print(voltage); Serial.println(“ volts”);

// now print out the temperature
float = (voltage — 0.5) * 100 ; //converting from 10 mv per degree wit 500 mV offset
//to degrees ((voltage — 500mV) times 100)
Serial.print(temperatureInC); Serial.println(“ degrees C”);

// now convert to Fahrenheit
float temperatureInF = ( * 9.0 / 5.0) + 32.0;
Serial.print(temperatureInF); Serial.println(“ degrees F”);

delay(10000); //waiting a second
}
