IoT Based Air Quality Monitoring System with Server Notification

The level of pollution has increased with times by lot of factors like the increase in population, increased vehicle use, industrialization and urbanization which results in harmful effects on human wellbeing by directly affecting health of population exposed to it. The Air Quality Monitoring System (AQM) is intended to educate people about the dangers of pollution. One of the notable aspects of the suggested system is that it is biased with IOT and that it provides warnings if sensors value crosses threshold value. This device is equipped with an LCD monitor to display the current amount of pollution. In order to monitor quality of air, a Wireless sensor network (WSN) based new framework is proposed which is based on data acquisition and transmission. The parameters of the environment to be monitored are chosen as temperature, humidity, volume of CO, volume of CO2, detection of leakage of any gas - smoke, alcohol, LPG. The value of temperature and humidity are transmitted over internet also so that every person in the range of the system can check it over their smart phones and laptops as these parameters hold importance to everyone. CO, a dangerous parameter is monitored with an extra precaution. A text message is sent to the base station through GSM module whenever its volume exceeds a particular safe limit intended for a particular application. The proposed system is also biased with the android application and it more helps to identify the data of pollutants all over the world by using Global Positioning System [GPS].
