Air Purifier with Thermoelectric Cooling and Advanced Air Monitoring Sensors

Abstract

Global air pollution presents a pressing concern impacting human well-being. The growing emphasis on indoor air quality (IAQ) and heightened demands for enhanced home comfort have fueled interest in innovative solutions. This research introduces a comprehensive system integrating real-time monitoring, air purification, and cooling technologies using sensors, filters, Ultraviolet light, and a Peltier Module. Effectively eliminating indoor pollutants like dust and microparticles, the device is equipped to detect smoke, methane, LPG, and carbon monoxide, while monitoring temperature and humidity. Post-purification, the air undergoes partial chilling for improved interior temperatures. Operated through a manual remote control and the 'BLYNK I. O. T. ' Android application, The system enables remote operation over long distances, extending its functionality to operate seamlessly through the internet. Assessments indicate a temperature decrease of 5.7 ⁰C in real-time monitoring accuracy. Furthermore, the project incorporates automated control functions for the cooling system, humidifier activation, and alarm notifications, responding from the output of the sensors. This holistic approach showcases the potential for future advancements in IAQ solutions and Heating, Ventilation, and Air Conditioning (HVAC) technologies.
