DEVELOPMENT OF AN AUTOMATED SMOKE-FILTERING ASHTRAY USING ARDUINO UNO WITH AN IGNITION SYSTEM AND STORAGE MECHANISM

Abstract

Indoor air pollution caused by cigarette smoke remains a serious health concern, particularly in enclosed spaces with poor ventilation. Exposure to second-hand smoke significantly increases the risk of respiratory illnesses, cardiovascular diseases, and cancer. Traditional ashtrays merely collect cigarette waste but do not mitigate the harmful airborne particles and gases emitted during smoking. This study aims to design and develop a multifunctional, automated ashtray that not only filters cigarette smoke but also includes features such as real-time maintenance notifications, a safe cigarette ignition system, automated waste handling, and a cigarette dispensing mechanism, all powered by a renewable solar energy system. The study employed an Experimental Prototyping Methodology alongside a Descriptive Survey Approach to design and evaluate the functionality of the automated smoke-filtering ashtray. The prototype integrated components such as an ignition system, smoke detection module, waste storage mechanism, SMS notification feature, and solar-powered backup system, with operations managed through four Arduino Uno microcontrollers. The prototype was successfully developed and demonstrated reliable integration of its key subsystems. These included a smoke filtration system, safe cigarette ignition, coin-operated cigarette dispenser, and real-time user notifications via SMS. The system was powered by both a conventional source and a solar backup, ensuring continuous operation. Feedback from initial testing indicated strong performance across all features, validating the ashtray’s potential for effective indoor smoke control. The findings suggest that combining microcontroller-based automation with health-conscious design offers a promising solution for indoor air pollution management. The system’s ability to filter smoke, automate waste disposal, notify users remotely, and operate sustainably supports its applicability in various settings such as homes, offices, and designated smoking areas. This innovation highlights the potential of engineering solutions in addressing public health concerns through smart and environmentally responsible technologies.
