4. While increasing air pollution, We developed an Advanced Air Quality
Monitoring System using nodemcu. The system involves monitoring the air
quality by considering parameters like Carbon dioxide, Smoke, Methane,
SNO2, Hydrogen, NH3, Benzene Particulate matter being a very important
parameter gives a clear indication of pollution in that particular time in the
area. These pollutant data are extracted using sensor like MQ135, MQ-2 , MQ-
7 . Most of these sensors produce analog output. Using software and coding of
the Arduino the data are taken and all values will be displayed on LCD
Display. This system would help to take real-time decisions and very effective
in today’s situation of high air pollution in most of the Indian cities.
ABSTRACT:
5. • Air is one of the important component of our biosphere. The quality of air is
changing day by day. All the industrialization affects the air quality so the
components of air, such as nitrogen, carbon dioxide, carbon monoxide, Sulphur
dioxide etc. are changing. These changes for gases are affecting the ecosystem. To
get an idea of this changing of quality and the quantity of pollutants over time our
project is used. This change in quality of the air is affecting humans as well as
other animals and plant health. Due to this high industrialization, large amount of
toxins is being introduced in the air, which are foreign.
INTRODUCTION:
6. EXISTING SYSTEM:
There are masks that protect us from rising air pollution, as well as numerous laws
that regulate air pollution. It is also vital to raise public awareness about the
dangers of air pollution.
It is vital to precisely estimate air quality.
There are a variety of traditional methods for measuring it, but the findings aren't
always exact, and it necessitates a lot of mathematical calculations
7. Existing System Drawbacks:-
Less amount of accuracy score
Small level dataset
Applicable on small level prediction work.
8. PROPOSED SYSTEM:
• In proposed system we are using gas sensors MQ135 and MQ2 with
controller NODEMUC it has more accuracy score it regulates air
pollution.
12. • I am suggesting you to buy NodeMCU because it is having inbuilt WIFI, you
can connect NodeMcu to internet without much effort compare to connecting
UNO to internet, and the best thing is NodeMCU is arduino compatible you
can do all possible stuff that can be done with UNO. We can also program
NodeMCU in 'C' language using Arduino IDE directly
Why NODMCU:
13. NODEMUC( esp8266v2)
ESP8266 ESP-01 Serial WIFI Transceiver Module is a cheap and
easy way to connect any small microcontroller platform, like Arduino,
wirelessly to Internet.
In our project we use it to make private network so we reserve a spot

14. MQ-135 GAS SENSOR:
The MQ-135 “Air Quality” sensor is part of the MQ series of
gas sensors that uses a chemical sensitive element. The
resistance of such element varies when exposed to certain
gases. The MQ-135 is sensitive to multiple gases including
Benzene, Acetone, Alcohol and Ammonium. Like all MQ gas
sensors, the MQ-135 follows a sensitivity curve
PIN1:Vcc(+5v)
PIN2:Ground
PIN3:Digital Out
PIN4:Analog Out
15. MQ-2 GAS SENSOR:
The MQ-2 Gas Sensor module is useful for gas leakage
detecting in home and industry. It can detect LPG, i-butane,
propane, methane ,alcohol, hydrogen and smoke. Some
modules have a built-in variable resistor to adjust the
sensitivity of the sensor. Note: The sensor becomes very hot
after a while, don't touch it!

PIN2:Ground
PIN3:Digital Out
PIN4:Analog Out
16. IOT:
Internet of things, IoT, is when physical objects are embedded with sensors, software, and
other technologies for the purpose of connecting and exchanging data with other devices
and systems
We are using to store cloud information other THING SPEAK web page.
Thing Speak is IOT Cloud platform where you can send sensor data to the cloud.
You can also analyze and visualize your data with MATLAB or other software,
including making your own applications. The Thing Speak service is operated by
Math Works
By Every Second We Can Update POLLUTION DATA
18. I2C:
The I2C interface only requires 2 data connections,
+5 VDC and GNDto operate

code, a message area, a text console, a toolbar with
buttons for common functions and a series of menus. It
connects to the Arduino hardware to upload programs
and communicate with them.
Download and install Arduino IDE
(https://www.arduino.cc/en/Main/Software)
Plug in your Arduino Board
Select the proper board in the IDE (Tools>Boards>Arduino Uno)
Select the proper COM port (Tools>Port>COMx (Arduino Uno))
