# Senseair S8 for Python

Python module for reading CO2 concentration from a Senseair S8 sensor connected to a Raspberry Pi

## Connecting the Senseair S8 to your Raspberry Pi

Hook up the Senseair S8 to your Raspberry Pi using the following schematic:

## Module installation

```bash

pip install senseair-s8

```

## Usage

As a module:

```python

from senseair_s8 import SenseairS8

senseair_s8 = SenseairS8()

print(senseair_s8.co2())

```

From the command line:

```bash

python -m senseair_s8

```

## Troubleshooting

- This module expects the sensor to be connected to port `/dev/ttyS0`. It was only tested using that port, but you can override this settings when initialising the sensor:

```python

sensair_s8 = SenseairS8(port='/dev/ttyS0')

```

- Out of the box, `/dev/ttyS0` is disabled on a Raspberry Pi, resulting in a `permission denied`-error. You can enable it by:

    1. Run `sudo raspi-config`

    2. Select Interfacting options

    3. Select P6 Serial

    4. Select No for login console

    5. Select Yes for serial port hardware

    6. OK, Finish, Reboot - Yes
