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.

Smart Mask for COVID-19 E-wear

COVID-19 has been one of the most disastrous pandemics of the decade which has impacted several human lives and global economy. It is really difficult to control this kind of problem in a developing country like India where we have huge population. It is also difficult to maintain social distancing in such places. So, we have come up with an idea for the people to self-monitor and protect themselves from the spread of the virus. This paper aims to implement a smart mask which uses digital technology, for detection, prevention and precaution from this deadly virus. This virus is bound to spread in the event of interaction with other people, and we use technology to detect and prevent the virus by forming a personalized mask, which is capable of monitoring your vitals and indicating if the patient is infected by the virus. We are integrating the heart rate pulse sensor, infrared thermometer—MLX90614, respiratory sensor and Dht11 sensor which are used to monitor the inner temperature and humidity present inside the mask. This sensor is mounted on the mask which helps us to monitor the person who is wearing it 24/7. The overall equipment is less bulky with all the required features, rechargeable and replaceable filter. The vitals are monitored through personalized cloud using ThinkSpeak and mobile-based monitoring with alert system. The mask has an OLED display for real-time monitoring. © 2022, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
