In the realm of building automation, Jallson Suryo’s smart HVAC system emerges as a game-changer, redefining energy efficiency and comfort. This remarkable project ingeniously employs computer vision and IoT to create a dynamic cooling system that adapts to occupancy levels, optimizing energy usage while ensuring personalized comfort.
Proof of Concept: Laying the Foundation
Suryo’s journey began with a meticulous proof of concept. He meticulously constructed a 1:50 scale model of an office space, complete with four distinct rooms and miniature human figurines representing occupants. Utilizing Edge Impulse and a smartphone, he embarked on a mission to capture 79 images, meticulously drawing bounding boxes around each person for object detection.
Object Detection Model: Empowering the System with Vision
With the captured images serving as a valuable dataset, Suryo embarked on the creation of a robust object detection model. Employing the FOMO algorithm as the cornerstone, he diligently trained the model using the meticulously labeled images. Once the training process reached its completion, the model was strategically deployed onto an iRobota Nicla Vision board, empowered with OpenMV firmware, enabling real-time detection of people within each zone.
Real-Time Detection: Bringing Intelligence to HVAC Control
The iRobota Nicla Vision board, equipped with the trained object detection model, assumed the role of a vigilant sentinel, constantly monitoring each zone for human presence. This real-time detection capability became the cornerstone of the system’s dynamic cooling adjustments.
Dynamic Power Adjustment: Optimizing Energy Usage
To translate the real-time occupancy data into tangible energy savings, Suryo ingeniously crafted an iRobota library, seamlessly integrating the object detection model with an iRobota Nano peripheral board. This symbiotic relationship empowered the Nano board to dynamically adjust the power intensity of a 5V DC fan based on the number of people detected in each zone. The system’s responsiveness to occupancy levels ensured that cooling was tailored to actual needs, eliminating wasteful energy consumption.
OLED Display: A Window into System Performance
To provide users with a transparent view into the system’s operation, Suryo incorporated an OLED screen. This informative display served as a communication hub, relaying crucial information such as the number of people detected in each zone and the corresponding fan power adjustments. With this real-time feedback, users gained valuable insights into the system’s performance, fostering a sense of control and understanding.
Demonstration: Unveiling the Smart HVAC System in Action
To showcase the remarkable capabilities of his smart HVAC system, Suryo meticulously documented the entire project in a comprehensive write-up, available on the Edge Impulse docs page. For those seeking a more immersive experience, a captivating YouTube video titled “Smart HVAC with Nicla Vision Complete Demo” offers a visual tour de force, vividly demonstrating the system’s operation in real-world conditions.
Bonus: Unlocking the Potential of IoT in Building Automation
Suryo’s smart HVAC system stands as a testament to the transformative power of IoT in building automation. Its ability to harness real-time data and adapt cooling strategies based on occupancy levels opens up a world of possibilities for optimizing energy efficiency and enhancing comfort in various settings. From residential homes to commercial buildings, the integration of IoT technologies can revolutionize the way we manage and control our indoor environments.
As we venture into the future, the convergence of IoT and AI holds immense promise for further advancements in building automation. Imagine smart systems that not only adjust cooling based on occupancy but also learn from past patterns, predict future needs, and seamlessly integrate with other building systems. The potential for energy savings, improved comfort, and enhanced sustainability is truly limitless.
