IoT Based Air Quality Monitoring System

Abstract

Today's world is solely dependent on the IoT. As the number of automated devices related to the IoT is increasing in the world, new technologies are constantly being invented. IoT is where data is sensed from the environment through hardware and that data is displayed online through the Internet in various software through the cloud. Many things can be monitored in real time through automated devices of various technologies connected to the IOT. Weather can be monitored in real time, through which it can be decided whether the weather in different regions or environments is good or bad for people. Because all kinds of airborne infectious diseases, industrial wastes, building construction, manufacturing and other sectors using high levels of chemicals are spread through this weather. This awareness has come only through the rapid development of technology. Through which the weather of any area or environment can be checked. That is, the number of harmful gases in the climate of a region or environment can be checked through automated devices of various technologies connected to the IoT. What is the number of harmful gases in the climate of an area or environment such as - temperature, humidity, altitude, topography, LPG, smoke, alcohol, hydrogen, carbon dioxide, carbon monoxide, butane, propane, methane, benzene, ammonia, Ozone, nitrogen dioxide, Sulphur oxide, dust concentration, particulate matter etc can be tested through the mentioned technology. In this paper we have developed an IoT device that can detect air quality and take decisions accordingly. Many types of hardware are used to detect harmful gas through this technology like Arduino Uno, Arduino Nano, Arduino Mega, Node MCU Esp8266 Module, Raspberry Pi, STM-32 Blue Pill Development board, MQ2, MQ4, MQ7, MQ9, MQ131, MQ135, LM939 , BMP-280 Sensor, MiCS2714 Sensor, PM 2.5 Sensor, PMSA003 Sensor, PMS-7003 Dust Sensor, DHT11, DHT22, Geophone Sensor, GPS Sensor, LED Sensor, air sensor, air sensor 6, buzzer, LCD Display, LDR, HK-A5, HC12 module, SIM800C module, sim800A module, DS-1307 real-time clock, 5-megapixel camera module, DC motor, analog to digital converter etc. After some time, we will use our built application's API to gather data. Weather monitor technology can be used to analyze the obtained values, the obtained data can be noted. Air quality of any area of Dhaka will be known through this project. Based on those criteria, Dhaka city will be divided into two level, such as Good and Bad. It will tell you that you have to use a mask in certain areas of Dhaka.
