Indoor Air Pollution Monitoring System (Mobile)

A mobile indoor air quality monitoring system for measuring humidity, temperature, volatile organic compounds, particulate matter and detecting concentration of various gases.

Getting Started

These instructions will get you a copy of the project up and running on your local machine. You will be able to access:

Live Dashboard
Webite
Thingspeak channels for both the nodes
OneM2M server containing data

Prerequisites

You will need Python 3 to run the Flask application for the Live Dashboard, it can be installed on Ubuntu/Debian using the following command:

$ sudo apt-get install python3 python3-pip

The other requirements can be installed as follows:

$ cd Indoor-Air-Pollution-Monitoring-System 
$ cd Live_Dashboard 
$ sudo -H pip install -r requirements.txt

You will need Arduino 1.8.9 or above along with the appropriate libraries included for the sensors to flash the code onto the NodeMCU.

Libraries Used

The following are the libraries included in the Arduino code for obtaining data from the node and sending it to the OneM2M server as well as Thingspeak.

//Libraries required for OneM2M communication
#include <JSONVar.h>
#include <Arduino_JSON.h>
#include <JSON.h>
#include <Wire.h>
#include <stdlib.h>

//Sensor Libraries
#include "Adafruit_SGP30.h"
#include "MutichannelGasSensor.h"
#include "SdsDustSensor.h"
#include "DHT.h"
#include "sgp30.h"
#include "sensirion_common.h"
#include <Adafruit_Sensor.h>
#include <SDS011.h>

//Libraries required for Thingspeak communication
#include <ThingSpeak.h>
#include <ESP8266HTTPClient.h>
#include <ESP8266WiFi.h>
#include <SoftwareSerial.h>
#include <Arduino.h>

Live Dashboard

The Live Dashboard contains real-time data in the form of SI Unit vs Time graphsas well the calculated AQI.

The Flask application can be run with the following commands after cloning this reposirory.

$ cd Indoor-Air-Pollution-Monitoring-System 
$ cd Live_Dashboard 
$ sudo -H pip install -r requirements.txt
$ python3 run.py

This will start the server and and the user will see a line as follows:

Running on http://127.0.0.1:5000/ (Press CTRL+C to quit)

Click on the HTTP link to acces the dashboard!

Email Alert System

Website

The Website contains a map of International Institute Of Information Technology, Hyderabad's campus and the graphs of data collected by the node at different indoor locations during three important time slots:

Before Diwali Friday 7/10/2019
During Diwali Saturday 8/10/2019
After Diwali Sunday 9/10/2019

Thingspeak

Visit the homepage for Thingspeak
Choose Channels from the nav bar at the top and search for the following channel numbers corresponding to sensors in the 2 nodes!

Channels for first node:

873276      //DHT Sensor
873290      //VoC and eCO2 Sensor
873271      //Nova PM Sensor
873290      //Grove Multichannel Gas Sensor

Chanel numbers for second node:

905895      //DHT Sensor
905904      //VoC and eCO2 Sensor
905893      //Nova PM Sensor
905902      //Grove Multichannel Gas Sensor

OneM2M

Insert method of setting up own server here when we figure out how to!

For now:

Visit onem2m.iiit.ac.in/webpage
Enter admin as the username
Enter admin as the password
Select Team 10 and click on the instances under the respective nodes to view the data collected.
