Portable Air Quality Monitoring and Controlling System Using Vacuum Draw-Off

Abstract

Air pollution is one of the most concerning facts of today’s world. Among all air pollution poses a serious threat for health. It affects human body through breathing and since this pollution is barely visible in eye, a monitoring system is necessary to stay cautious. This is the motivation behind our work so that in hospital all people can stay aware of the toxic gas (CO) they are breathing. Our objective is to provide a system to measure continuous Air Quality in hospital environment and AQI level using gas sensors and also an inbuilt fire detector is present to determine fire out broken. We proposed a portable model in which monitoring sensors are connected through IoT technology. From previous dataset we got high accuracy. In this model our aim to detect the toxic gas and fire outbreak by using the gas sensor MQ2, MQ7, MQ135 and flame sensor. When the toxic gas is detected, the vacuum can automatically run and suck the toxic gas. In addition to this, it provides alert to the main device which is connected through IOT and buzzer. we included fire detector, DHT11-temperature and moisture to maintain the environment in hospital. Whenever the temperature and moisture are crossed the normal range, it gives alert to the device (mobile) by Bluetooth. Also, we're going to use the air purifier model to reduce the problems.
