Automated Control of DIY Air Purifier with AC Fan

Abstract

This project aims to develop an innovative automated control system for a DIY AC air purifier fan, designed to enhance indoor air quality. By effectively detecting and activating the AC fab with a Filtrete filter based on sensor data, the system efficiently eliminates pollutants like smoke, dust, and allergens from the air. The project addresses the challenge of inconsistent and inefficient performance of homemade air purifiers, which can have adverse on individuals’ health and well-being in indoor environments. This project involves the seamless integration of hardware and software components, utilizing Arduino, particulate matter, and air quality sensors, in conjunction with an AC box fan, relay, and LCD display for control and monitoring purposes. Through continuous comparison of sensor data with predefined threshold values, the system intelligently determines the optimal activation of the filter, ensuring the maintenance of high air quality. The results highlight the accuracy and effectiveness of the filtration mechanism, showcasing the system’s capability to monitor and control air quality in an efficient manner. In conclusion, this automated control system offers a user-friendly and cost-effective solution, promoting healthier and more comfortable living or working spaces.
