I0T based air pollution monitoring system
Project Area of Specialization Internet of ThingsProject SummaryAir pollution is the biggest problem of every nation. Health problems have been growing at faster rate especially in urban areas of developing countries where industrialization and growing number of vehicles leads to release of lot of gaseous pollutants, include mild allergic reactions such as irritation of the throat, eyes and nose as well as some serious problems like bronchitis, heart diseases, pneumonia, lung.
Previously we have built LPG DETECTOR using MQ6 sensor and smoke sensor but this time we use MQ135 sensor which is best choice for monitoring the air as it can detect most harmful gasses IOT Based Air Pollution Monitoring System monitors the Air quality over a web server using Internet and will trigger an alarm when the air quality goes down beyond a certain threshold level, means when there are sufficient amount of harmful gases present in the air like CO2, smoke, alcohol, benzene, NH3, LPG and NOx. It will show the air quality in PPM on the LCD and as well as on webpage so that it can monitor it very easily. The system can be installed anywhere but mostly in industries and houses where gases are mostly to be found and gives an alert message when the system crosses threshold limit.
Project ObjectivesTo study various sensors and related technologies.To study IOT for efficient communication between sensors and controllers.
To develop & deploy low cost sensor based controllers for air pollution measurement.
To develop a monitoring system for air pollution.
Project Implementation Methodproject planing------workflow analysis------design-----implimentation----testing-----maintainance---
Benefits of the Project- The data collected from air quality monitoring helps us assess impacts caused by poor air quality on public health.
- Air quality data helps us determine if an area is meeting the air quality standards devised by CPCB, WHO or OSHA.
- The data collected from air quality monitoring would primarily help us identify polluted areas, the level of pollution and air quality level.
- Air quality monitoring would assist in determining if air pollution control programmes devised in a locality are working efficiently or not.
- Air quality data helps us understand the mortality rate of any location due to air pollution. We can also assess and compare the short term and long term diseases/disorders which are a result of air pollution.
- Based upon the data collected control measures can be devised for protection of environment and health of all living organism
