Analog Temperature Sensor with Arduino

Eli the Computer Guy Arduino, Arduino - Sensor Basics

You can use Analog Temperature Sensors in Arduino Projects to determine the temperature in your environment.

Functional Parts in the Project:

#define sensorPin  A0

void setup()
{
  Serial.begin(9600);
}

void loop()
{
  int reading = analogRead(sensorPin);
  float voltage = reading * 5.0;
  voltage /= 1024.0;
  float temperatureC = (voltage - 0.5) * 100 ;
  float temperatureF = (temperatureC * 9.0 / 5.0) + 32.0;

  Serial.print(voltage); Serial.print(" volts  -  ");
  Serial.print(temperatureC); Serial.print(" degrees C  -  ");
  Serial.print(temperatureF); Serial.println(" degrees F");

  delay(3000);
