PROBLEM STATEMENT

• Air pollution is one of environmental issues that cannot be ignored.

• Inhaling pollutants for a long time causes damages in human health.

• Traditional air quality monitoring methods, such as building air quality monitoring stations, are typically expensive.

• This project is suitable for air quality monitoring in real-time.

INTRODUCTION

• The purpose of our device is to monitor the quality of air using different sensors.

• Sensors data is then collected in controller and transmitted through GSM module to PC where it is calibrated and displayed to user.

• The data is stored in database in order to extract information for future use.

COMPONENTS

• Sensorso MQ-7(Carbon mono-oxide sensor)o MQ-131(Ozone sensor) o MQ-135(Smoke sensor/air pollution)o MQ-136(Hydrogen sulphide sensor)o MICS-2714(Nitrogen dioxide sensor)

• Controllero Arduino UNO-R3

• GSM module(transmitter/receiver)

Working

• MQ-7 is a 6-pin device that is used to detect concentration of CO in air.

• VCC=5V• Can detect CO-gas concentrations

anywhere from 20 to 2000ppm.• High sensitivity and fast response time

CONTD..

• MQ-131 gas sensor is used to detect O3 concentration in air.

• It’s also 6 pin device, 4 of them are used to fetch signals, and other 2 are used for providing heating current.

• VCC=5V• Can detect O3 concentration form 10ppb-2ppm• Fast response and high sensitivity.

CONTD..

• MQ-135 is used for detecting a wide range of gases, including NH3, NOx, alcohol, benzene, smoke and CO2.

• 6 pin device.• VCC=5V• Detecting concentration scope 10ppm-300ppm

NH3• 10ppm-1000ppm Benzene• 10ppm-300ppm Alcohol

CONTD..

• MQ-136 sensor used to detect the concentration of hydrogen sulphide present in air.

• 6 pin device but since we are using module MQ-131 thus it has 4 pins o 1. VCC=5vo 2.DOUT(Digital output)o 3.AOUT(Analogue output)o 4.GND

• Detecting concentration scope: 1-100ppm H2S

CONTD..

• MICS-2714 is a robust MEMS sensor for nitrogen dioxide and leakage detection.

• Detectable gases• Nitrogen dioxide NO2 0.05 – 10ppm• Hydrogen H2 1 – 1000ppm

1.)Hardware part2.)Gantt chart3.) Documented Work4.)Visited EPA for data collection and sensors info

CHALLENGES

• Collection of data/calibration.o Visited EPA thrice.o They just imported devices from japan and

they only know how to operate. They don’t know the how that device works.

• Sensor ordered but not received yet thus we just stimulate how sensors will work.

CONCLUSION

• Till mid of December our sensors will arrive (sir Kashif Islam)

• Interface with controller will then be completed

• In FYP-2 prototype of device and its GUI on PC will be completed.

• Data will be then verified by EPA.
