In this paper, we can identify the design, development, and implementation of an IoT-enabled solar-powered air purification and monitoring system, aimed at providing sustainable and real-time solutions for indoor and semi-outdoor environments. The developed system makes use of PM2.5, MQ135, and DHT11 continuing monitoring critical air quality parameters which consist of particulate matter, the concentration of toxic gases, temperature, and humidity; and identifies these parameters before and after the air purifier. Centralized control and data processing are carried out by one ESP32 microcontroller, which controls the operation of the air purifier's blower and transmits sensor data wirelessly to the ThingSpeak IoT cloud platform. Furthermore, the developed system benefits from a solar panel and battery backup which allows for an off-grid energy-efficient system; therefore, the developed. [i.e. solar-powered air purification and monitoring system] is especially suitable because of its energy-efficient design for installation where power is not constant, such as semi-outdoor environments. Information on real-time feedback is available locally (through an LCD display) and remotely (via an SDK cloud platform), so users can be aware of the pollution in the air wherever they are located. For example, it can be useful to compare differences in performance between different types of filters such as HEPA filters and filter paper, showing a meaningful difference in pollution level reductions. A review of the literature highlights an original contribution combining solar power, IOT connections, multi-stage sensors, and filter designs on one platform provides an effective and definitive way to manage air quality. The research findings demonstrated the prototype platform significantly improves air quality with sustainable energy consumption and efficiency in a comprehensive, practical, scalable, and low-cost manner to combat air pollution in home, institutional, and rural communities.
