The Health Benefits of Improved Air Quality Through a Mini Ozone Generator in Train Compartments

In this project, we focus on enhancing air quality within train compartments through an integrated system comprising gas sensors, an Arduino controller, and a mini ozone generator. Trains, often characterized by confined spaces and high passenger density, can experience significant air quality issues due to elevated levels of CO2 and various harmful gases. To address these concerns, our system utilizes the MQ135 sensor to detect CO2 levels and the MQ6 sensor to monitor the presence of other gases such as methane and LPG. Data from these sensors are processed by an Arduino microcontroller and displayed in real-time on an LCD screen for easy monitoring by train staff.When the sensors detect CO2 or gas levels exceeding predefined thresholds, the Arduino triggers a relay to activate the mini ozone generator. Ozone, known for its powerful oxidizing properties, is used to neutralize pollutants and improve overall air quality. By employing this proactive approach, the system aims to create a healthier and more comfortable environment for passengers. The use of the mini ozone generator, managed by the Arduino, ensures that the air remains fresh, reducing the risks associated with poor air quality, such as respiratory issues and discomfort, thereby enhancing passenger well-being during their journey.
