Design of IoT Based Indoor Air Purifier

An IoT-based system for monitoring the quality of the air within a building, which includes a "Smart-Air"air quality sensor on a web server. IoT and cloud storage are used to evaluate the quality of the air at any time and from any place. Smart-Air is a product of the Internet of Things (IoT), a device that uses LTE to broadcast real-time data on air quality to a web server. Today, air pollution is a leading cause of preventable mortality and disease across the world. Pollution has become a major concern all around the globe. The discharge of chemicals or unfriendly compounds has a devastating impact on human, animal, and plant life. This is referred to as pollution. Many studies have been conducted on different air purification techniques because of this. Air purifiers that utilize HEPA filters, activated carbon, and UV light are discussed in this paper. The water and chemicals that an air purifier sprays into the air will spread out contaminants. © 2022 IEEE.

But it will only lead to better result if the students are actually learning during this process. Hence, it becomes very important to know the perception of the students for online learning. This research article highlights the major factors affecting the student's experience of online learning. For this questionnaires are filled by 110 students and responses collected are analysed using principle component analysis. As a result we came across major four factors effecting the perception of students towards online learning and also Covid 19 has significant impact on the number of students engaged in online learning. © 2023 Contributors and Manakin Press.
