Key Takeaways
- The Roomba Air Quality Sentinel is an innovative device that transforms a Roomba vacuum cleaner into an air quality monitoring system, enabling users to visualize and map indoor air pollution.
- The Roomba’s RGB LED changes color based on the levels of volatile organic compounds (VOCs) detected, providing a visual representation of air quality in different areas of a room.
- PLOTS’ open-source approach and the availability of the project details encourage collaboration and community involvement in tackling indoor air quality challenges.
In a world where air quality concerns are rising, a team of creative minds at PLOTS (Public Laboratory for Open Technology and Science) has devised a novel solution. They’ve transformed a humble Roomba robot vacuum cleaner into an air quality sentinel, embarking on a mission to map indoor air pollution.
The Air-Sensing Roomba: A Revolutionary Approach
The modified Roomba, equipped with an air quality sensor, embarks on a journey through your living space, diligently sniffing out the presence of volatile organic chemicals (VOCs) such as ammonia, alcohol, and carbon dioxide. These VOCs often lurk in our homes, emitted from various sources like cleaning products, paints, and even our own breath. The Roomba’s sensitive sensor detects these gases and translates them into a visual representation.
Visualizing Air Quality: Color-Coding the Room
To make the air quality assessment accessible and visually appealing, the Roomba is adorned with an RGB LED. As it roams, the LED changes color based on the air sample it encounters. Green indicates a healthy air environment, while yellow signals moderate levels of VOCs. When the Roomba detects high concentrations of pollutants, the LED turns red, urging you to investigate the source and take action.
Capturing Air Quality Patterns: Long Exposure Photography
The PLOTS team has devised an ingenious method to create visual maps of air quality distribution within a room. By taking long exposure photographs while the Roomba roams, they capture a trail of colored lights. These photographs reveal areas with high VOC concentrations, allowing you to pinpoint potential sources of pollution and address them accordingly.
Open-Source Design: Empowering the Community
In the spirit of open innovation, PLOTS has made the details of their project publicly available on their website. This transparent approach encourages others to replicate and improve upon their work, fostering a collaborative effort to tackle indoor air quality challenges.
Hamster Ball Air Sensing: An Alternative Approach
PLOTS is also exploring an alternative approach to air sensing, utilizing a hamster ball. This spherical contraption houses an air quality sensor and roams freely around a room, collecting data on VOC levels. The hamster ball’s unique design allows it to navigate tight spaces and gather air samples from various heights, providing a comprehensive assessment of indoor air quality.
Bonus: The Art of Clean Air
The PLOTS team’s innovative work serves as a reminder of the importance of clean air in our living spaces. By visualizing air quality, we gain a deeper understanding of our indoor environment and can take proactive steps to improve it. Simple measures like opening windows for ventilation, using non-toxic cleaning products, and avoiding smoking indoors can significantly enhance air quality and contribute to our overall well-being.
The PLOTS team’s dedication to open-source innovation and their pursuit of creative solutions to real-world problems are truly inspiring. Their work empowers us to take control of our indoor air quality and create healthier living spaces for ourselves and future generations.
