Chapter 12 - Arduino-Based Smart Garden System: Using RS485 Sensor with SMS Notification for Real-Time Plant Condition Management by: Kenneth D. Dela Rama, Ralph Ed Emerson Cayosa, John Adams Magsigay et.al

The Arduino Smart Garden Monitoring and Automatic Irrigation System is one innovative move towards the modernization of traditional gardening through sensor technologies and automation. The system continuously monitors important environmental factors such as Soil moisture, pH, EC, temperature, and NPK level. Alongside this, it employs an automated irrigation system to regulate the optimal growth of plants and minimize water waste. The findings indicate that the Arduino-based Smart Garden system significantly improves plant growth and resource management, making it a promising alternative to conventional gardening techniques. Tripathy et al. (2015) identified that automation in gardening not only enhances productivity but also conserves essential resources, while Selvaraj et al. (2021) provided evidence that real-time sensor monitoring can effectively track and manage environmental parameters. In addition, Ameer et al. (2024) underscored the importance of precise nutrient calibration to maintain optimal soil conditions, and York & Wiseman (2012) highlighted the critical role of proper soil management in plant development. This study applied Quasi-Experimental research and used purposive sampling to gather insights from Evaluators from Benigno "Ninoy" S. Aquino High School. Mallick and Biswait (2024) demonstrated the transformative impact of integrating Arduino-based automation with horticulture, while Kumar et al 2021) validated the efficiency of sensor-driven systems in optimizing water usage and reducing manual labor. These studies reinforce the possibility of using automated Smart Garden systems as a sustainable alternative to traditional gardening methods. Respondents evaluated that the Smart Garden system is highly suitable for Agricultural and urban gardening applications. The improved water conservation, enhanced plant health, and overall received ratings of "Very High Potential" in terms of efficiency, while ease of use and reliability were rated with "High Potential." Overall, these findings confirm the system's potential and reliability, highlighting its capability to transform traditional gardening practices, promote urban sustainability, and contribute to a more resource-efficient future. Keywords: Smart Garden, Arduino, automated irrigation, sensor technology, sustainable agriculture, water conservation.The Arduino Smart Garden Monitoring and Automatic Irrigation System is one innovative move towards the modernization of traditional gardening through sensor technologies and automation.
