Configuration Options Description
Basically, you can think of the package as a black box with one input (sensor data) and many outputs. For now only SDS011 sensor is supported, but if you are familiar with Python it'd be easy to add other sensors as well.
Have a look at configuration file:
{
"general":{
"publish_interval":30
},
"comstation":{
"enable":false,
"port":"/dev/ttyUSB0",
"work_period":300,
"geo":"",
"public_key":""
},
"httpstation":{
"enable":true,
"port":8001
},
"luftdaten":{
"enable":true
},
"robonomics":{
"enable":true,
"ipfs_provider":"/ip4/127.0.0.1/tcp/5001/http",
"ipfs_topic":"airalab.lighthouse.5.robonomics.eth"
},
"datalog":{
"enable":false,
"path":"",
"suri":"",
"remote":"wss://substrate.ipci.io",
"dump_interval":3600,
"temporal_username":"",
"temporal_password":""
},
"dev":{
"sentry":""
}
}At the moment it's possible to publish data to Luftdaten, Robonomics Network and Datalog. The last one is experimental!
DO NOT edit
config/default.jsonfile. Instead make a copy
Play around with the configuration!
Explanation of options:
| Field | Description |
|---|---|
general/publish_interval | integer number from 1 and above. Tells how often send measurements. Keep in mind that if measurements from sensors come less often than this number connectivity sends last data |
comstation/enable | true/false. Enabling/disabling the station |
comstation/port | valid path to com port, for example /dev/ttyUSB0. It is where a sensor is connected to |
comstation/work_period | integer from 0 to 1800. For SDS011 sensor 0 means continuous work. Recommended period is 300 seconds |
comstation/geo | lat,lon a string with two floats separated by a comma. It represents latitude and longitude of a sensor |
comstation/public_key | Ed25519 verifying key in hex format. If not provided connectivity generates a new one |
httpstation/enable | true/false. Enabling/disabling the station |
httpstation/port | what port listen to |
luftdaten/enable | true/false. Whether or not publish data to Luftdaten. Don't forget to register the sensor's mac address on the site |
robonomics/enable | true/false. Whether or not publish data to IPFS topic according to Robonomics communication protocol |
robonomics/ipfs_proveder | an endpoint for IPFS daemon. By default it's /ip4/127.0.0.1/tcp/5001/http that means local daemon. The endpoint must by in multiaddr format. For example for Infura.io it would be /dns/ipfs.infura.io/tcp/5001/https |
robonomics/ipfs_topic | IPFS topic's name. If you want to use DApp provided by Robonomics team leave it untouched |
datalog/enable | true/false. Enable/Disable saving log to Robonomics on Substrate chain |
datalog/path | full path to robonomics executable file. You can find the latest release on this page |
datalog/suri | a private key from substrate chain account |
datalog/remote | an endpoint to substrate instance |
datalog/dump_interval | specify a period of time for collecting log in seconds |
datalog/temporal_username | set username to upload files to Temporal.Cloud (Optional) |
detalog/temporal_password | set password to upload files to Temporal.Cloud (Optional) |
dev/sentry | for development purpose. If you have a Sentry.io account you can put sentry's credentials in here |
Scenario #1: Connect SDS011 to serial port
The easiest and the most straightforward way to connect your sensor to the network is using the serial port
Connect you SDS011 sensor to a USB port, let's assume it got /dev/ttyUSB0 address
{
"general":{
"publish_interval":30
},
"comstation":{
"enable":true,
"port":"/dev/ttyUSB0",
"work_period":300,
"geo":"59.944954,30.294534",
"public_key":""
},
"httpstation":{
"enable":false,
"port":8001
},
"luftdaten":{
"enable":true
},
"robonomics":{
"enable":true,
"ipfs_provider":"/ip4/127.0.0.1/tcp/5001/http",
"ipfs_topic":"airalab.lighthouse.5.robonomics.eth"
},
"datalog":{
"enable":false,
"path":"",
"suri":"",
"remote":"wss://substrate.ipci.io",
"dump_interval":3600,
"temporal_username":"",
"temporal_password":""
},
"dev":{
"sentry":""
}
}Scenario #2: Connect SDS011 via HTTP
Connectivity Configuration
{
"general":{
"publish_interval":30

"comstation":{
"enable":false,
"port":"/dev/ttyUSB0",
"work_period":300,
"geo":"59.944954,30.294534",
"public_key":""
},
"httpstation":{
"enable":true,
"port":8001

"luftdaten":{

"robonomics":{
"enable":true,
"ipfs_provider":"/ip4/127.0.0.1/tcp/5001/http",
"ipfs_topic":"airalab.lighthouse.5.robonomics.eth"

"datalog":{
"enable":false,
"path":"",
"suri":"",
"remote":"wss://substrate.ipci.io",
"dump_interval":3600,
"temporal_username":"",
"temporal_password":""
},
"dev":{
"sentry":""
}
}Do not forget to open the port in system firewall
On NixOS you can do:
networking.firewall.allowedTCPPorts = [ 31313 ];
Scenario #3: Connect Multiple Sensors and Publish to Datalog
Install Robonomics
From root user do:
echo "https://github.com/airalab/airapkgs/archive/nixos-unstable.tar.gz nixos" > /root/.nix-channels
nix-channel --update
Then edit /etc/nixos/configuration.nix and add:
...
environment.systemPackages = with pkgs; [
substrate-node-robonomics-bin
];
...
Run rebuild and find out where robonomics is:
nixos-rebuild switch
whereis robonomics
Let's assume you got the following path: /nix/store/2gz2ik17w5xad8w819bsb05a23pbjbya-system-path/bin/robonomics
