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