Students Make Smart Gardening Simple

Written By: Tina Alvey Dale

For many aspiring gardeners, success comes down to one simple challenge: Remembering to care for their plants. A student research team at the University of Arkansas 鈥� Fort Smith set out to solve that problem by blending technology with sustainability. Their result is a smart, self-managing greenhouse designed with everyday users in mind.

Mckenzie Otwell and Kaden McGatha presented their research project, Auto-Green: Self-Watering Plant System, at 91看片网鈥� 19^th Annual Student Research Symposium April 10. The team, under the supervision of faculty sponsor Dr. Kiyun Ha Han, associate professor of smart systems engineering, designed, programmed, and constructed a self-watering plant system using knowledge gained from their electrical engineering technology classes over the years.

Using mostly recycled materials, the team built a compact greenhouse capable of housing small to medium-sized plants. But the real innovation lies in what happens inside that structure.

The system monitors soil moisture and automatically waters plants when needed, taking the guesswork out of gardening and being especially handy when gardeners just forget. It also tracks temperature and humidity, activating built-in fans to regulate the environment and protect plants from overheating.

The goal of the project is straightforward. It makes gardening more accessible. Time constraints often discourage people from growing their own food, even as interest in healthier, more sustainable living continues to rise, Mckenzie said.

鈥淚 know many people who garden and have tried to garden. The biggest factor in its success or failure is time. It is so easy to forget to water your plants, and we want this research to help people with that struggle,鈥� Mckenzie said.

By creating an affordable, easy-to-replicate system, the team looks to empower others to start gardening without feeling overwhelmed.

鈥淭his can show people not only how to garden, but how to build something like this themselves,鈥� Mckenzie said. 鈥淲e wanted to make it approachable using resources people might already have.鈥�

The impact could be wide-ranging, she added. Beginners can use the system as a learning tool to gain a better understanding of plant care. Experienced gardeners can rely on it to maintain smaller crops like herbs, freeing up time for larger projects.

The idea for the project grew from personal curiosity. Wanting to learn how to garden, Mckenzie combined an interest in technology with a practical goal. Along the way, the team gained hands-on experience in designing and refining a working product, spent hours troubleshooting code, revised schematics, and improved usability.

Mckenzie, a senior engineering major set to graduate in the fall, is already applying those skills in the real world as an engineering intern, with plans to transition into full-time. Her time at 91看片网 has played a key role in shaping that path, providing both technical experience and professional opportunities.

At its core, the project reflects a simple but powerful idea: with the right tools, anyone can grow something.
