3. Introduction
• The main objective of this project is to monitor the air eminence in
industrial and urban areas.
• In this Arduino platform is used to communicate the data simply and
quickly.
• WSN (Wireless sensor network) acts as the trans receiver.
communication technology.
• The projected monitoring system can be transferred to or shared by
different applications. Through IOT we can able to visualize the values
from the globe.
• Keywords – Wireless Sensor Network(WSN), Air Quality Monitoring
Systems (AQMS), Gas Sensors (CO).

6. Hardware/Software Requirement
• Arduino. (ATMEGA328)
• IOT.(node MCU)
• Air quality sensor.
Software Tools -
• Proteus.
• Arduino. (1.8.0)
Hardware Tools -

7. Arduino Board
• Arduino is open-source hardware.
• An Arduino board consists of an Atmel 8-, 16- or32-bit AVR
microcontroller (ATmega8,ATmega168, ATmega3,ATmega1280,
ATmega2560).
• Arduino microcontrollers are pre-programmed with
a boot loader that simplifies uploading of programs to the on-chip flash
memory.
• Boards are loaded with program code via a serial connection to
computer.
• The Arduino board exposes most of the microcontroller's I/O pins for
use by other circuits.

8. PIN DISCRIPTION OF ATMEGA328

9. Existing System
BLUETOOTH
• Drawback: it passes information only one device.
GSM
• Drawback: when signals drops it passes information slowly.
ZIGBEE
• Drawback: we need more than one zigbee. It is cost
effective and more expansive

10. Proposed System
IOT(internet of things)

11. Proposed System
IOT(NODE MCU)
• Node mcu is an open source iot platform.
• It includes firmware which runs on the ESP8266 WIFI SOC from
Espressif Systems,and hardware which is based on the ESP-12
module.
• The firmware uses the Lua scripting language.
• It is based on the eLua project,and built on the Espressif Non-OS
SDK for ESP8266.
• It uses many open source projects,such as lua- cjson,and spiffs.

12. Air Quality Sensor
• Gas Sensor(MQ2) module is useful for gas leakage detection. (home and
industry)
• It is suitable for detecting H2, LPG, CH4, CO, Alcohol, Smoke or Propane.
• Due to its high sensitivity and fast response time, measurement can be
taken as soon as possible.
• The sensitivity of the sensor can Be
adjusted by potentiometer.

13. Features & Advantages
Features –
• Wide detecting scope.
• Stable and long life time.
• Fast response.
Advantages -
• Sensors are easily available.
• Detecting a wide range gases like CO2,CO etc.
• Simple , compact and easily handle.
• Continous update of change in percentage of quality.

14. Application/Future Work
Application -
• Roadside pollution monitoring.
• Industrial perimeter monitoring.
• Site selection for reference monitoring stations.
• Indoor air quality monitoring.
Future Work -
In future the project can be upgraded in more ways than one.
• Interface more no.of sensors to know gases present in air.
• Design webpage and upload data on webpage.
• Interface SDCARD to store data.
• Interface GPS module to monitor the pollution.

15. Conclusion
• The system to monitor the air of environment using arduino micro
controller.
• Iot technology proposed to improve quality of air.
• Gas sensor gives the sense of different type of dangerous
gases.
• It supports new technology and healthy life concept.
