In the lush, miniature ecosystems of terrariums, a silent revolution is underway, driven by the unassuming power of tiny sensors and microcontrollers. Diva Septiawan, a researcher from the University of Mataram in Mataram, Indonesia, has harnessed the potential of the Internet of Things (IoT) to transform plant care in these self-contained worlds. Her work, published in the International Journal of Electrical, Energy and Power System Engineering, offers a glimpse into a future where technology and nature coexist in harmonious symbiosis.
Septiawan’s IoT-driven solution is a marvel of simplicity and efficiency. At its core lies an ESP32 microcontroller, accompanied by DHT11 and YL-69 sensors, a relay, and a mini DC pump. This ensemble monitors crucial environmental parameters—temperature, humidity, and soil moisture—and automates irrigation, ensuring that plants receive the precise care they need. “The system is designed to mimic the natural processes that plants rely on for growth,” Septiawan explains. “By automating these processes, we can create an optimal environment for plant growth, even in the most controlled settings.”
The implications of this research extend far beyond the confines of a terrarium. In the energy sector, where efficiency and sustainability are paramount, IoT-driven plant care could revolutionize the way we approach green spaces in urban environments. Imagine smart parks and green roofs that require minimal human intervention, yet thrive under the watchful eye of IoT sensors. This could lead to significant reductions in water usage and energy consumption, aligning perfectly with the sector’s push towards sustainability.
The study involved a 14-day observation of Rombusa plant growth, revealing that the optimal soil moisture level for these plants ranges between 60%–70%, averaging 65%. This precision in care is a testament to the potential of IoT in agriculture and horticulture. “The findings confirm that IoT-driven plant care enhances growth efficiency and simplifies maintenance,” Septiawan notes. “This offers a more effective alternative to traditional methods, which often rely on guesswork and manual labor.”
The integration of an Android application, developed with Android Studio and Arduino IDE, further enhances the system’s usability. The app, which connects to the IoT system via Firebase, provides real-time data access, allowing users to monitor their plants’ health from anywhere. This level of connectivity and control is a game-changer, not just for hobbyists but for commercial growers as well.
As we look to the future, the potential for IoT-driven solutions in plant care is vast. From smart greenhouses to automated urban gardens, the technology could reshape how we interact with and care for our green spaces. Septiawan’s work, published in the International Journal of Electrical, Energy and Power System Engineering, is a significant step in this direction, offering a blueprint for a more efficient, sustainable, and technologically advanced approach to plant care.
