thermometer library for IoT

Project description

===
python thermometers
===

idea: read data from various thermometers

reality: we have one dallas 18s20 connected via 1wire what is mostly used on RaspberryPi

PULL REQUEST FOR ANOTHER DEVICES ARE WELCOME

supported logger
----------------

'thermometer.d18s20.w1' write data from thermometer to logger as list of values, this allow to use i.e. fluent for
store data into graphite or another type of data storage.


instalation
------------
```
pip install thermometer

```

basic usage
-----------
measured values are in degrees of Celsius

```
>>> from thermometer.dallas_18s20 import w1
>>> w = w1.dallas_18s20()
>>> w.get_temps_aliases()
[('870155007fff0c108a', 24.437), ('080255007fff0c10a5', 32.5)]

```


alias usage
-----------
measured values are in degrees of Celsius

```
>>> from thermometer.dallas_18s20 import w1
>>> w = w1.dallas_18s20()
>>> w.alias('870155007fff0c108a', 'temp1')
>>> w.get_temps_aliases()
[('temp1', 24.437), ('080255007fff0c10a5', 32.5)]

```

Note about Dallas 18S20 and 18B20
---------------------------------

during development I found out there are two Dallas thermometers 18S20 and 18B20
- *DS18S20* High-Precision 1-Wire Digital Thermometer, 10.000010EF0000
- *DS18B20* Programmable Resolution 1-Wire Digital Thermometer, 28.000028D70000


so far name was badly chosen, for 18s20 it was wrong, regarding historical instalations I decide to let it be.
Interesting resource about 1Wire devices: http://owfs.sourceforge.net/adapters/patch.html
