# 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
* MAX31850
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](https://datasheets.maximintegrated.com/en/ds/DS18B20.pdf) (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)
