Arduino Library for Maxim Temperature Integrated Circuits
This library supports the following devices :
- DS18S20 - Please note there appears to be an issue with this series.
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)
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
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@example.com originally developed this library. Tim Newsome firstname.lastname@example.org added support for multiple sensors on the same bus. Guil Barros [email@example.com] added getTempByAddress (v3.5) Note: these are implemented as getTempC(address) and getTempF(address) Rob Tillaart [firstname.lastname@example.org] added async modus (v3.7.0)
