Description
Air pollution is a growing global concern that poses severe risks to human health, ecosystems, and climate. Traditional monitoring systems are often limited in coverage, costly, and incapable of providing real-time localized data. To address these challenges, this project proposes an IoT-based automated detection system for air pollution that leverages low-cost sensors, ARDUINO controllers, and cloud platforms to continuously monitor air quality.
The system integrates gas and particulate sensors (for pollutants such as CO, CO₂, NO₂, SO₂, and PM₂.₅/PM₁₀) with an IoT-enabled controller to collect environmental data. Using wireless communication protocols, the data is transmitted to a cloud server where it is processed, analyzed, and visualized through dashboards and mobile applications. This automated detection framework provides cost-effective, and real-time monitoring, enabling individuals, communities, and policymakers to make informed decisions. By bridging the gap between traditional monitoring and modern IoT solutions, the project contributes to smart city development, public health protection, and sustainable environmental management.
Note- add
Automated detection system for air pollution is the project of last year’s engineering projects, BE final year engineering project. This project is used for the BE last year’s Electronics, electrical and Tele. Communication department students. This project is a Electronics project. This project is electronics and Tele. Communication department students. This project is mini project.
Automated detection system for air pollution is the project of a good price for the engineering projects. It is a very comparative engineering project. It is a very good BE final year project. It is a project for ARDUINO based project. This project is sensor based project as well as ESP8266 based project .
The engineering projects give in the ELECTROSAL HI- TECH PVT.LTD. The best place for the degree final year engineering projects as well as for Electronics ,electrical and electronics and Tele. Communication students’ final year for the golden opportunity.
Automated detection system for air pollution is an easy project and idea for the electronics ,electrical and Tele . Communication base students and 100% output is done.
HIGHLIGHTS
- It is necessary to monitor air quality and keep it under control for a better future and healthy living for all.
- The sensors interact with Arduino UNO which processes this data and transmits it over internet.
- Core monitoring and detection-Multi-pollutant sensing:Measure key pollutants (PM2.5, PM10, NO₂, SO₂, O₃, CO, VOCs) with appropriate sensors.
- Real-time data capture:Continuously sample and stream data with minimal latency.
