Arduino_Project-IOT

• Welcome to my first official Arduino IOT project.
• The goal of this project is to create a smart-home implementation using my Arduino RP2040.
• As a start the Arduino will monitor the internal temperature.
• Future plan is to connect other smart devices and ultimately monitor the whole house.

Todo list

The project is now postponned, because my Arduino connector broke :/

• Implement all Docker images.
• Connect Arduino to the MQTT client and publish the data.
• Visualize data from Arduino on Grafana dashboard
• Arduino simulator that sends random temperature to MQTT subscriber
• Start a Telegram bot that will notify you about events.
• Enable more functionalitios for InfluxDB
• Improve Grafana dashboards

Orion Context Broker

The brain of your IOT network. Orion is a C++ implementation of the NGSIv2 REST API binding developed as a part of the FIWARE platform.

• To access Orion go to: http://localhost:1026/v2

IOT Agent

An IoT Agent is a component that lets a group of devices sends their data to and be managed from a Context Broker using their own native protocols. The API used here is NGSIv2.

• To access IOT Agent go to: http://localhost:4041/iot/about
• Implementation example

MQTT Broker

MQTT is a publish-subscribe-based messaging protocol used in the internet of Things

• Serves as a middleman between IOT devices (sensors) and Fiware network.

Telegraf

Telegraf is a server-based agent for collecting and sending all metrics and events from databases, systems, and IoT sensors.

• The raw data is sent to InfluxDB, therefore you can visualize them in Grafana.
• How does it work? Telegraf intro

InfluxDB

Smart data collector for your IOT devices.

• Introduction to InfluxDB Documentation

MongoDB

Simple database image to hold temporary data.

• Used by the Orion Context Broker to hold context data information such as data entities, subscriptions and registrations
• Used by the IoT Agent to hold device information such as device URLs and Keys

Grafana

Visually display the data from IOT devices (sensors).

• By default Grafana will have an InfluxDB configured with the available data.
• To access grafana go to: http://localhost:30001
  

Prerequsities & References:

• Must have knowledge: Orion Context basics
• Fiware IOT MQTT documentation: Fiware docs
• Fiware IOT MQTT repository: Github repo

Checklist:

• Installed Docker on your system. previous experience recommended
• Arduino (RP2040)
  • Arduino device or extensions that can connect to MQTT broker via Wi-fi
• Postman or cURL command interface
• Programming skills
• Patience & time

Setup:

0. Laptop (PC) should be connected to the same network as Arduino (Hotspot)
1. ./services start
   • Check if all docker images are running
2. In new terminal run:
   • MQTT subriber docker logs --tail 10 mosquitto

• to check if mqtt is running and arduino01 is connected docker run -it --rm --name mosquitto_sub --network fiware_arduino_default --platform linux/amd64 efrecon/mqtt-client:latest sub -h mosquitto -p 1883 -t '/#'
• to run the subscriber and listen to data incoming from arduino

3. Run Script
   • temperature_sensor.py
   • door_detection.py
