ABSTRACT

Measuring Air Quality is an important element for bringing lot of awareness in the
people to take care of the future generations a healthier life.

Based on this, Government of India has already taken certain measures to ban ‘Single
Stroke’ and ‘Two Stroke’ Engine based motorcycles which are emitting high pollutions
comparatively. We are trying to implement the same system using IoT platforms like Thing
speak or Cayenne, we can bring awareness to every individual about the harm we are doing to
our environment.
Already, New Delhi is remarked as the most pollution city in the world recording Air
Quality above 300PPM. We have corrected the other papers where they have wrongly
calibrated the sensor and wrongly projecting the PPM values. We have also used easiest
platform like thing speak and set the dashboard to public such that everyone can come to know
the Air Quality at the location where the system is installed. Also, we have reduced the cost of
components used on comparing with the papers referred.

CHAPTER 01

INTRODUCTION

Nowadays the air condition is very polluted. In recent years, car emissions, chemicals
from factories, smoke, and dust are everywhere. That is the reason why now air condition is
very polluted. The effect of air pollution is very bad for our health, especially for a place where
the air in our body is taken for breathing.

Air pollution cannot be detected by human feelings. Air pollution may contain a lot of
dangerous substances such as ozone, particulate matter sulfur dioxide, nitrogen dioxide, carbon
monoxide, and lead. This proposed system uses a wireless sensor network with low-cost
sensors and hardware components along the necessary software to effectively monitor the air
pollution phenomenon.

Air pollution is the worst environmental problem and it causes a multitude of adverse
effects on human health, water bodies, and climate. The main source of air pollution in all
major cities is due to vehicles and the second major source remains the industries. The air
pollution monitoring system is installed in a particular locality where there are traces of acute
air pollution to detect the constituent gases of air which may lead to harmful effects on human
health and other leaving beings. Substances in the polluted air are very dangerous.

For example, if the carbon monoxide is above 100ppm, it makes humans feel dizzy,
nauseous, and within minutes they could die. This research makes humans find out which
content of the air is polluted. With Bluetooth module, we can monitor the air pollution
remotely, because there is a Bluetooth module in mobile. This makes the air condition can be
monitored every time.

Continued exposure to environments with poor air quality is a major public
health concern in developed and developing countries. It is estimated that the pollutants
responsible for poor air quality cause nearly 2 million premature deaths per year world-wide.
Significantly, around 1 million of these deaths are due to polluted indoor air, and it is
suggested that poor indoor air quality may pose a significant health risk to more than half of
the world’s population. Due to its link with industrialization, societal health problems
associated with poor air quality disproportionately affects developed and developing nations –
it is estimated that air pollution is responsible for the premature deaths. Remedial action to
improve air quality is often easy to implement once airborne pollutants have been detected.

This project provides a combination of process of sensing several gas levels in
the air and also the ambient temperature and humidity, thus sensing the quality of the air. The
levels of the gases and the temperature is displayed in a LCD display panel, which continuously
shows the real time output values of the gas sensors, temperature and humidity sensor. Air is
getting polluted because of release of toxic gases by industries, vehicle emissions and increased
concentration of harmful gases and particulate matter in the atmosphere. The level of pollution
is increasing rapidly due to factors like industries, urbanization, increasing in population,
vehicle use which can affect human health. Particulate matter is one of the most important
parameters having the significant contribution to the increase in air pollution [2]. This creates
a need for measurement and analysis of real-time air quality monitoring so that appropriate
decisions can be taken in a timely period. This paper presents a real-time standalone air quality

low-cost air quality system was discussed in 2008 because at that time the sensors were quite
expensive and also the system.

The industrial air pollution monitoring system for safety and health enhancement was
introduced to know the hazardous gasses and their impact. By using the mobile GPRS system
the air pollution information could be transmitted. Wireless sensor network-based pollution
monitoring system in metropolitan cities was introduced to know the air quality. The pollution
Dynamic Monitoring System is also done previously. We need a smart environment monitoring
system with IoT support to know the information on the mobile itself.

The purpose of air quality monitoring is to assess the level of pollution in relation to air
quality standards. These standards are a regulatory measure to set the target for pollution
reduction and ultimately achieve clean and breathable air.

These are the motivation of that we are choosing the project to detect the Air Quality
Monitoring System.

CHAPTER 1.

OBJECTIVE

To measure and display temperature and humidity level of the environment.

To combine advanced detection technologies to produce an air quality sensing system with
advanced capabilities to provide low-cost comprehensive monitoring.

To display the sensed data in user friendly format in LCD display panel.

For making this project some components are required like Arduino uno, Jumper wires,
HC05 Bluetooth module, MQ 135 Gas Sensor Bread board.

CHAPTER 02

LITERATURE SURVEY

These are the paper articles that are published in the different news papers and online article
websites about air quality monitoring.

CHAPTER 03

PROPOSED APPROACH

In the hardware part we are using Lcd, power supply, Jumper wires, MQ135 air
quality this sensor, is used to detect CO2, CO, Ammonia as well as smoke. Followed by
Bluetooth module why we are using means we need to display this data to the application
because Arduino doesn't have Bluetooth capacity so that we use this chip and connect this
Bluetooth to our mobile Bluetooth 5V Power supply is one of the most common power supplies
in use today. H44780 Character LCD is an industry-standard LCD Display device for
interfacing with embedded systems. Here we are using 16X2 Configuration 4-bit write mode
in this project. We use electromagnet inside the Buzzer In the software part we are using as an
alert. we created the application also for observation of output.

Arduino uno

Arduino UNO is a microcontroller board based on the ATmega328P. It has 14 digital
input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz ceramic
resonator, a USB connection, a power jack, an ICSP header and a reset button. It contains
everything needed to support the microcontroller; simply connect it to a computer with a USB
cable or power it with an AC-to-DC adapter or battery to get started. You can tinker with your
UNO without worrying too much about doing something wrong, worst-case scenario you can
replace the chip for a few dollars and start over again.

MQ

The gas sensor module consists of a steel exoskeleton under which a sensing element
is housed. This sensing element is subjected to current through connecting leads. This current
is known as heating current through it, the gases coming close to the sensing element get
ionized and are absorbed by the sensing element. This changes the resistance of the sensing
element which alters the value of the current going out of it.
