Configuration Options Description

Basically, you can think of the Sensors Connectivity module 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.

At the moment it's possible to publish data to Luftdaten and Robonomics Network Datalog. Robonomics team has prepared a few ready-to-use configurations. You can find the full overview of the configuration fields here.

This Article contains advanced configurations scenarios. If you haven't read the previous article "Sensors Connectivity Module Setup" yet, please read it first.

#Scenario #1: Connect SDS011 to serial port

The easiest and the most straightforward way to connect your sensor to the network by the serial port.

First, connect you board to a USB port, and find path to board with next command:

$ ls -l /dev/serial/by-id
total 0
lrwxrwxrwx 1 root root 13 сен  5 14:01 usb-1a86_USB2.0-Ser_-if00-port0 -> ../../ttyUSB0

In the example it is ttyUSB0. Now you need to create a new configuration file, or edit the existing configuration file from the previous article. Insert what you see below to the configuration file. Write the full path to your database in the file.

{
   "general": {
      "publish_interval": 30,
      "db_path": ""
   },
   "comstation":{
      "enable":true,
      "port":"/dev/<YOUR-PATH-TO-BOARD>",
      "work_period":300,
      "geo":"00.000000,00.000000",
      "public_key":""
   },
   "httpstation": {
      "enable": false,
      "port": 8001
   },
   "mqttstation": {
      "enable": false,
      "host": "localhost",
      "port": 1883
   },
   "luftdaten": {
      "enable": false
   },
   "robonomics": {
      "enable": true,
      "ipfs_provider": "/ip4/127.0.0.1/tcp/5001/http",
      "ipfs_topic": "airalab.lighthouse.5.robonomics.eth"
   },
   "datalog": {
      "enable": false,
      "suri": "",
      "dump_interval": 60,
      "temporal_username": "",
      "temporal_password": "",
      "pinata_api": "",
      "pinata_secret": ""
   },
   "dev": {
      "sentry": ""
   },
   "frontier": {
      "enable": false,
      "suri": ""
   },
   "trackagro": {
      "enable": false,
      "token": ""
   }
}

And start Sensors Connectivity module.

#Scenario #2: Connect SDS011 via MQTT

Attention, Robonomics sensors firmware doesn't work with MQTT. These settings for additional sensors, which work through MQTT. Example of those sensors you can find here.

Let's assume you already have MQTT broker mosquitto or similar.

Again as in the previous scenario you need to create a new configuration file, or edit the existing configuration file from the previous article. Insert what you see below to the configuration file. Write the full path to your database in the file.

Sensors Connectivity Module will listen /freertos_mqtt_robonomics_example/ topic.

{
   "general": {
      "publish_interval": 30,
      "db_path": ""
   },
   "comstation":{
      "enable":false,
      "port":"/dev/ttyUSB0",
      "work_period":300,
      "geo":"",
      "public_key":""
   },
   "httpstation": {
      "enable": false,
      "port": 8001
   },
   "mqttstation": {
      "enable": true,
      "host": "<MQTT-broker-host>",
      "port": <MQTT-broker-port>
   },
   "luftdaten": {
      "enable": false
   },
   "robonomics": {
      "enable": true,
      "ipfs_provider": "/ip4/127.0.0.1/tcp/5001/http",
      "ipfs_topic": "airalab.lighthouse.5.robonomics.eth"
   },
   "datalog": {
      "enable": false,
      "suri": "",
      "dump_interval": 60,
      "temporal_username": "",
      "temporal_password": "",
      "pinata_api": "",
      "pinata_secret": ""
   },
   "dev": {
      "sentry": ""
   },
   "frontier": {
      "enable": false,
      "suri": ""
   },
   "trackagro": {
      "enable": false,
      "token": ""
   }
}

And start Sensors Connectivity module.

#Scenario #3: Publish sensors data to Datalog

In this scenario it doesn't matter how data is being gathered: over HTTP, MQTT or COM. Let's look at the default HTTP configuration.

This scenario shows how to upload your sensor's data to Robonomics Parachain Datalog. Robonomics Datalog is analog of "Telemetry" in Web3 technologies. Datalog function is meant to create a sensor's data snapshot each period of time, which increase reliability of data.

Just like in the previous scenario you need to create a new configuration file, or edit the existing configuration file from the previous article. Insert what you see below to the configuration file. Write the full path to your database in the file.

Here we work with datalog field. It includes next lines:

• suri - a private key from robonomics parachain account;
• dump_interval - specify a period of time for collecting log in seconds;
• temporal_username, temporal_password - Credentials to upload files to Temporal.Cloud (Optional);
• pinata_api, pinata_secret - Credentials to upload files to pinata service(Optional).

Insert what required to file:

{
   "general": {
      "publish_interval": 30,
      "db_path": ""
   },
   "comstation":{
      "enable":false,
      "port":"/dev/ttyUSB0",
      "work_period":300,
      "geo":"59.944954,30.294534",
      "public_key":""
   },
   "httpstation": {
      "enable": true,
      "port": 8001
   },
   "mqttstation": {
      "enable": false,
      "host": "localhost",
      "port": 1883
   },
   "luftdaten": {
      "enable": false
   },
   "robonomics": {
      "enable": true,
      "ipfs_provider": "/ip4/127.0.0.1/tcp/5001/http",
      "ipfs_topic": "airalab.lighthouse.5.robonomics.eth"
   },
   "datalog": {
      "enable": true,
      "suri": "<YOUR-SECRET-KEY>", 
      "dump_interval": 60,
      "temporal_username": "",
      "temporal_password": "",
      "pinata_api": "",
      "pinata_secret": ""
   },
   "dev": {
      "sentry": ""
   },
   "frontier": {
      "enable": true,
      "suri": ""
   },
   "trackagro": {
      "enable": false,
      "token": ""
   }
}

And start Sensors Connectivity module.
