IoT Solar-Powered Rooftop Vent With IAQ Control

What it does

This IoT-integrated, solar-powered rooftop ventilator with smart IAQ control automatically adjusts airflow based on real-time air quality data. It reduces energy consumption, improves indoor air quality, and is designed to resist Malaysia's tropical climate.

Your inspiration

The idea to solve this problem from the growing concerns about poor indoor air quality and its impact on health, particularly in Malaysia's tropical climate. I was inspired by the need for a more energy-efficient and environmentally friendly solution to improve air circulation in enclosed spaces. Traditional systems were not enough to handle and pollutants like CO₂ and VOCs, which led to the development of a smarter, more sustainable system powered by solar energy. By integrating IoT technology, this design allows real-time monitoring and automatic adjustments, offering a more efficient way to maintain healthy indoor environments.

How it works

The solar-powered rooftop ventilator works by capturing sunlight using solar panels. The energy generated by the solar panels powers the ventilator, ensuring it operates without relying on non-renewable energy sources. Inside the system, sensors continuously monitor the air quality, detecting pollutants like carbon dioxide (CO₂) and volatile organic compounds (VOCs). When the air quality decreases, the system automatically adjusts the airflow to improve ventilation. This adjustment is made possible through IoT technology, which allows users to monitor and control the system remotely using a smartphone or computer. The system also includes smart features like real-time monitoring, which automatically increases the ventilation when pollutants are detected, ensuring a healthier and more comfortable indoor environment.

Design process

It began with identifying the key problems: poor indoor air quality and the inefficiency of traditional ventilation systems in Malaysia’s tropical climate. We began by researching existing solutions, analysing their shortcomings, and understanding customer needs through surveys. From there, we brainstormed and generated several conceptual designs. We evaluated these concepts using criteria such as energy efficiency, ease of installation, and weather resistance. The most promising concept focused on integrating solar power, IAQ sensors, and IoT technology for real-time monitoring. We then created CAD models for all components, including the solar panel, ventilation lid, fan blades, and structural frame. Prototypes were developed, beginning with a basic working model to test airflow and solar efficiency. Upon testing, improvements were made to optimize airflow, durability, and weather resistance, addressing issues like the strength of materials and enhancing the modularity for easier installation. The final prototype included improvements based on real-world feedback, such as a dual-louver design for enhanced weather protection and modular components for easier assembly. We also focused on user-friendly features, allowing users to control the system remotely via an app.

How it is different

What sets our design apart is the seamless integration of solar power, IoT technology, and real-time air quality monitoring. Unlike traditional ventilation systems, which rely on constant energy consumption and lack adaptability, our system adjusts airflow dynamically based on the real-time air quality data from IAQ sensors. This reduces unnecessary energy usage and enhances efficiency. Additionally, the modular design makes installation and maintenance easier, while the dual-louver system ensures durability against Malaysia's tropical climate, protecting the system from rain, debris, and humidity. The combination of sustainability, smart technology, and ease of use makes it a unique and forward-thinking solution in the ventilation market.

Future plans

The next steps for this design include integrating a filter to enhance air purification, adding more IAQ-related sensors for more comprehensive monitoring, and implementing mechanisms to prevent insects and birds from entering the system. Additionally, we plan to refine the design to make it more commercial, aiming for wider adoption in both residential and industrial markets. These improvements will increase the system’s efficiency and appeal, positioning it as a more advanced and versatile solution for indoor air quality management.
