DallasTemperature

Arduino Library for Maxim Temperature Integrated Circuits

Usage

This library supports the following devices :

• DS18B20
• DS18S20 - Please note there appears to be an issue with this series.
• DS1822
• DS1820
• MAX31820

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'.

In case of temperature conversion problems (result is -85), strong pull-up setup may be necessary. See section Powering the DS18B20 in DS18B20 datasheet (page 7) and use DallasTemperature(OneWire*, uint8_t) constructor.

We have included a "REQUIRESNEW" and "REQUIRESALARMS" definition. If you want to slim down the code feel free to use either of these by including

#define REQUIRESNEW 

or

#define REQUIRESALARMS

at the top of DallasTemperature.h

Finally, please include OneWire from Paul Stoffregen in the library manager before you begin.

Credits

The OneWire code has been derived from http://www.arduino.cc/playground/Learning/OneWire. Miles Burton miles@mnetcs.com originally developed this library. Tim Newsome nuisance@casualhacker.net added support for multiple sensors on the same bus. Guil Barros [gfbarros@bappos.com] added getTempByAddress (v3.5) Note: these are implemented as getTempC(address) and getTempF(address) Rob Tillaart [rob.tillaart@gmail.com] added async modus (v3.7.0)
