**New:** use [w1thermsensor as a CLI tool](#usage-as-cli-tool)! - Since version *0.3.0*

## Supported devices

The following w1 therm sensor devices are supported:

* DS18S20
* DS1822
* DS18B20
* DS28EA00
* DS1825/MAX31850K

## Setup

You just need a w1 therm sensor.

Some of them can be bought here: [Adafruit: DS18B20](https://www.adafruit.com/search?q=DS18B20)

I've used a Raspberry Pi with an GPIO Breakout (Pi Cobbler). Other hardware like the Beagle Bone are supported, too.

## Installation

### From PIP

This possibility is supported on all distribution:

pip install w1thermsensor

*Note: maybe root privileges are required*

### On Raspbian using apt-get

If you are using the `w1thermsensor` module on a Rasperry Pi running raspbian you can install it from the offical repository:

```bash
sudo apt-get install python-w1thermsensor
```

Or if you are using python 3:

```bash
sudo apt-get install python3-w1thermsensor
```

### Create debian packages

For python 2:

python setup.py --command-packages=stdeb.command bdist_deb

For python 3:

python3 setup.py --command-packages=stdeb.command bdist_deb

## Usage as python package

The usage is very simple and the interface clean..
All examples are with the `DS18B20` sensor - It works the same way for the other supported devices.

### Basic usage with one sensor (implicit)

```python
from w1thermsensor import W1ThermSensor

sensor = W1ThermSensor()
temperature_in_celsius = sensor.get_temperature()
temperature_in_fahrenheit = sensor.get_temperature(W1ThermSensor.DEGREES_F)
temperature_in_all_units = sensor.get_temperatures([
W1ThermSensor.DEGREES_C,
W1ThermSensor.DEGREES_F,
W1ThermSensor.KELVIN])
```

The need kernel modules will be automatically loaded in the constructor of the `W1ThermSensor` class.

If something went wrong an exception is raised.

*The first found sensor will be taken*

### Basic usage with one sensor (explicit)

The DS18B20 sensor with the ID `00000588806a` will be taken.

```python
from w1thermsensor import W1ThermSensor

sensor = W1ThermSensor(W1ThermSensor.THERM_SENSOR_DS18B20, "00000588806a")
temperature_in_celsius = sensor.get_temperature()
```

### Multiple sensors

With the `get_available_sensors` class-method you can get the ids of all available sensors.

```python
from w1thermsensor import W1ThermSensor

for sensor in W1ThermSensor.get_available_sensors():
print("Sensor %s has temperature %.2f" % (sensor.id, sensor.get_temperature()))
```

Only sensors of a specific therm sensor type:

```python
from w1thermsensor import W1ThermSensor

for sensor in W1ThermSensor.get_available_sensors([W1ThermSensor.THERM_SENSOR_DS18B20]):
print("Sensor %s has temperature %.2f" % (sensor.id, sensor.get_temperature()))
```

## Usage as CLI tool

The w1thermsensor module can be used as CLI tool since version `0.3.0`.

### List sensors

List all available sensors:

```
$ w1thermsensor ls
$ w1thermsensor ls --json # show results in JSON format
```

List only sensors of a specific type:

```
$ w1thermsensor ls --type DS1822
$ w1thermsensor ls --type DS1822 --type MAX31850K # specify multiple sensor types
$ w1thermsensor ls --type DS1822 --json # show results in JSON format
```

### Show temperatures

Show temperature of all available sensors: (Same synopsis as `ls`)

```
$ w1thermsensor all --type DS1822
$ w1thermsensor all --type DS1822 --type MAX31850K # specify multiple sensor types
$ w1thermsensor all --type DS1822 --json # show results in JSON format
```

Show temperature of a single sensor:

```
$ w1thermsensor get 1 # 1 is the id obtained by the ls command
$ w1thermsensor get --hwid 00000588806a --type DS18B20
$ w1thermsensor get 1 # show results in JSON format
```
