Integrated Air Purification System in Two-Wheeler Helmets

Abstract - Air pollution is a major menace to riders of two-wheeled vehicles due to its hazardous effects on their health. In most cases, this is evident in urban areas characterized by constant traffic. Helmets offer riders with physical protection without considering the type and quality of air that the rider inhales. The major contributors to decreased air quality include vehicle emissions and dust. This article proposes and discusses IoT-based Integrated Air Purification System in Two- Wheeler Helmets that have the ability to detect environmental changes and offer clean air instantly. The system uses an MQ135 gas sensor and a DHT11 sensor that detects environmental changes such as temperature and humidity. The ESP32 microcontroller is responsible for processing these data and automatically turning on the fan and filter system whenever environmental changes go beyond specified limits. This system also uses an OLED display that offers instant data and is connected to a mobile application through Blynk IoT technology. Experiments contributed significantly towards proving that this technology is effective in improving air quality within a two-wheeled vehicle helmet and also offers significant comfort to riders as well as reduces risks associated with riders inhaling large amounts of polluted air..
