Spark Core compatible Dallas Temperature sensor library

This library is a port of the Arduino Dallas Temperature Sensor library. Some includes have been fixed, but the libary is otherwise untouched.

Note: This library depends on the OneWire library, so be sure to include it in your project too.

Original repository by Miles Burton: Arduino-Temperature-Control-Library.

This library supports the following devices:

  • MAX31850 - New!
  • DS18B20
  • DS18S20 - Please note there appears to be an issue with this series.
  • DS1822
  • DS1820

You will need a pull-up resistor of about 5 KOhm between the 1-Wire data line and your 5V power. If you are using the DS18B20, ground pins 1 and 3. The centre pin is the data line '1-wire'.

Example code

!! Make sure to include the libraries !!

// Init Dallas on pin digital pin 3
DallasTemperature dallas(new OneWire(D3));

void setup(){

void loop(){
    float celsius = dallas.getTempCByIndex( 0 );
    Serial.print("Temperature: "); Serial.println(celsius) ;
