NodeGuard: WioTerminal MQTT Air Quality Monitor

Transforming air quality monitoring with cutting-edge technology. Our system combines advanced sensors and real-time analytics for proactive

Inspired by the recent fire outbreak at the solid waste dumpsite in Brahmapuram, Kochi, this project emerges as a comprehensive solution not only tailored to address the immediate environmental concerns of the incident but also designed with a broader vision. While the Brahmapuram fire serves as a catalyst for our initiative, the objective extends beyond a singular event to create an adaptable and scalable Air Quality Monitoring System applicable to various scenarios akin to the challenges faced in Kochi.

The impetus for this endeavor lies in recognizing the critical need for continuous air quality monitoring in the face of unforeseen incidents, such as fires and industrial activities, that can significantly impact the well-being of communities. By leveraging advanced sensor technology, real-time data analytics, and robust communication systems, our project aims to provide a proactive and versatile solution applicable to diverse situations.

This introduction sets the stage for understanding the dual purpose of our project: to address the immediate aftermath of the Brahmapuram fire and to establish a framework for a broader, scalable system that can be employed in various contexts where air quality monitoring is paramount.

Problem Statement
Despite advancements in waste management, the recent fire outbreak at the solid waste dumpsite in Brahmapuram, Kochi, highlights the persisting challenges associated with environmental emergencies. The incident not only led to hazardous air quality conditions but also posed significant health risks for the residents of Kochi and neighboring areas. The lack of an effective real-time air quality monitoring system exacerbated the impact of the fire, making it challenging to implement timely interventions.

The problem extends beyond this specific event, reflecting a broader issue of inadequate infrastructure for continuous air quality monitoring in many regions. Without proactive measures, communities remain vulnerable to the consequences of environmental incidents, such as fires, industrial accidents, or waste mismanagement. Therefore, the pressing problem is the absence of a comprehensive and scalable air quality monitoring solution that can address both immediate crises and serve as a preventive measure for future occurrences.

Solution Overview
To address the critical need for efficient and comprehensive air quality monitoring, our project draws inspiration from the recent fire outbreak at the Brahmapuram solid waste dumpsite in Kochi. We present an innovative solution designed to provide real-time monitoring of air quality in high-risk areas, with the capability to adapt to various environmental challenges.

The core components of our solution include a robust hardware platform, advanced sensors, and a centralized data processing system. Leveraging state-of-the-art technology, our project aims to create a scalable and adaptable air quality monitoring system applicable in diverse scenarios, similar to the challenges faced during the Brahmapuram incident.

By providing a comprehensive and adaptable solution, our project aims to contribute to the development of a robust air quality monitoring infrastructure that goes beyond reactive responses to environmental emergencies. The lessons learned from the Brahmapuram incident serve as a catalyst for developing a system with broader applications and the potential to safeguard communities in various high-risk scenarios.

Now the first step to doing our project is setting up the wio terminal this can be done by following the steps,

Welcome to the world of Wio Terminal! In this easy tutorial, we’ll walk you through updating the Wireless Core Firmware on your Wio Terminal to unlock exciting new features. Don’t worry if you’re new to this – we’ll keep it simple, and you’ll be a pro in no time!

now some of you maybe thinking why do I need to upgrade this firmware thingy.because new updates always comes with bugfixes and having the latest firmware ensures that there are no pesky bugs between you and your wio terminal

Materials Needed:

- Wio Terminal
- Computer (Windows, macOS, or Linux)
- Internet connection

Step 1: Get Ready with Arduino:

- Make sure your Wio Terminal is connected to your computer.
- Download the firmware update files (uf2 files) from the provided link.(click here).
- Slide the Wio Terminal’s power switch twice quickly. When the blue LED starts breathing differently, check your computer for a new drive called “Arduino.”

Step 2: Update Firmware:

- Drag the downloaded rtl8720_update_v2.uf2 file into the Arduino drive. Your Wio Terminal will reset, and you’ll see “Burn RTL8720 fw” on the screen – it means the firmware update is in progress.

Step 3: Download Latest Firmware:

- Download the latest firmware for RTL8720 from the given link(click here).

Step 4: Download Flash Tool:

- Download the flash tool from the provided repository link.(this is a link for the github repository there is button called code in the repository click it then click download zip from there to download the whole repository).

Step 5: Erase Initial Firmware:

- Open PowerShell (for Windows) or Terminal (for macOS/Linux) in the flash tool directory.(go to the space where u downloaded the flash tools then right click and select open terminal option).
Make sure that the folder containing the flashtool must be in the desktop so that no error occurs”
