The IoT-based air purification system is an advanced and intelligent solution designed to monitor and improve indoor air quality in real-time. Air pollution has become a major concern due to increasing industrialization, urbanization, and vehicular emissions, which lead to harmful health effects such as respiratory problems and allergies. This system uses various air quality sensors to detect pollutants such as carbon dioxide (CO₂), carbon monoxide (CO), smoke, dust particles, and other harmful gases present in the environment. The collected data is processed using a microcontroller like Node MCU or Arduino, which continuously analyzes air quality levels. When pollution levels exceed the safe threshold, the system automatically activates the air purification unit. The purifier may include components such as a High Efficiency Particulate Air (HEPA) filter, an activated carbon filter, and an exhaust fan to remove dust, odor, and toxic gases effectively. Through internet of things (IoT) technology, the system sends real-time air quality data to a cloud platform or mobile application, allowing users to monitor and control the purifier remotely. Additionally, the system can be powered by renewable energy sources such as solar panels to enhance sustainability and reduce electricity consumption. This smart and automated approach ensures energy efficiency, user convenience, and improved health conditions. The IoT-based air purification system is suitable for homes, offices, hospitals, and industrial environments, providing a cost-effective and reliable solution for maintaining clean and healthy air.
