Robonomics package to read data from sensors and publish to different output channels

Project description

Sensors Connectivity Module for Decentralized Sensors Network

The module for launching your own server instance for receiving data from sensors (like SDS011) and their further processing.

Available Guides

We have created a nice complete guide that reveals the idea of the Decentralized Sensors Network and the Sensors Connectivity module. The guide is available at Robonomics Academy:

https://robonomics.academy/en/learn/sensors-connectivity-course/overview/

Pre-requirements

IPFS daemon should be installed to build this package. Assuming you work on Linux:

wget https://dist.ipfs.io/go-ipfs/v0.8.0/go-ipfs_v0.8.0_linux-amd64.tar.gz
tar -xzf go-ipfs_v0.8.0_linux-amd64.tar.gz
cd go-ipfs
sudo bash install.sh
ipfs init

You also need at least Python3.10.0 to run this project.

Sensor Preparation

To prepare a sensor for the work with the package follow instructions on Robonomics Academy.

Installation as PyPi package

Run the following commands:

pip3 install py-sr25519-bindings
pip3 install sensors-connectivity

Configuration

At Robonomics Academy you can find an article to set a proper configuration for your instance:

https://robonomics.academy/en/learn/sensors-connectivity-course/sensors-connectivity-config-options/

Launch

First, launch IPFS daemon:

ipfs daemon --enable-pubsub-experiment

After configuration and log files are set, you can run the service in another terminal:

sensors_connectivity "path/to/your/config/file"

You will see logs in your terminal and in ~/.logs.

Build from Source

To build a python package from source Poetry should be also installed. Assuming you work on Linux:

curl -sSL https://raw.githubusercontent.com/python-poetry/poetry/master/get-poetry.py | python -

Get a package and install dependencies:

git clone https://github.com/airalab/sensors-connectivity
cd sensors-connectivity
poetry install

Configuration

At Robonomics Academy you can find an article to set a proper configuration for your instance:

https://robonomics.academy/en/learn/sensors-connectivity-course/sensors-connectivity-config-options/

Make a copy of default.json and fill it using description from the article.

You also can set a logging file. The default file for logs is logging.py, which uses console and file handler by default. Pay attention to the file handler.

The template is stored in connectivity/config/logging_template.py. You can specify the path (filename), where your logs will be stored in (do not forget to create this directory if it doesn't exist). Default path for logs is ~/.logs. You can find any other handlers in the Logging facility module for Python.

Launch

First, launch IPFS daemon:

ipfs daemon --enable-pubsub-experiment

After configuration and log files are set, you can run the service in another terminal:

poetry run sensors_connectivity "path/to/your/config/file"  

If your log file is set with console handler, you will be able to see logs in your terminal.

Development

To test the module with HTTP station use:

poetry run test_mobile_lab
test_environmental_box

For more information about development check /docs directory:

Troubleshooting

Python.h: No such file or directory::

If during running poetry install command you get such error, you need to install the header files and static libraries for python-dev. Use your package manager for installation. For example, for apt you need to run:

sudo apt install python3-dev

Note: python3-dev does not cover all versions for Python 3. The service needs at least Python 3.10, for that you may need to specify the version: sudo apt install python3.10-dev.

Here you can find examples for other package managers.

Python versions mismatch:

If during running poetry install command you get SolverProblemError, which says The current project's Python requirement (3.6.9) is not compatible with some of the required packages Python requirement:.., even though you have older version of Python (e.g. Python 3.10.9), you may need to specify the Python version for Poetry:

poetry env use python3.10.9
