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).

8. ARDUINO Arduino is open-source hardware. An Arduino board consists of an  Atmel 8-, 16- or 32-bit AVR  microcontroller  (ATmega8, ATmega168,  ATmega328 , 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.

10. EXISITING 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

11. PROPOSED SYSTEM IOT(internet of things)

12. The Internet of Things (IoT) is a system of interrelated computing devices, mechanical and digital machines, objects, animals or people that are provided with unique identifiers . IoT has evolved from the convergence of wireless technologies, micro-electro mechanical systems (MEMS), micro services and the internet. also used in operational technology (OT), information technology (IT).

13. NODE MCU Nodemcu 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. PROPOSED SYSTEM IOT(NODE MCU )

15. AIR QUALITY SENSOR

16. 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.

17. FEATURES Wide detecting scope. Stable and long life time. Fast response.

18. 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.

19. APPLICATIONS Roadside pollution monitoring. Industrial perimeter monitoring. Site selection for reference monitoring stations. Indoor air quality monitoring.

20. FUTURE SCOPE 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.

21. 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.
