  1. Abstraction – The rising need for environmentally friendly farming methods, along with the accelerating consumption of freshwater resources across the world, requires shifting away from conventional irrigation techniques. In this paper, an innovative approach is presented by designing and developing a Smart Plant Irrigation System using Internet of Things (IoT) hardware combined with Artificial Intelligence (AI) software. The goal is to increase water efficiency in use while providing the best plant growth environment.

    The system's fundamental architecture is built around an ESP8266 microcontroller, which serves as the central processing unit, connecting environmental sensors like DHT11 (temperature and humidity) and soil moisture sensors. They provide real-time data acquisition from the farming field. The analog signals are converted into digital and processed to allow autonomous decisions for the irrigation events.

    AI models are utilized to examine past and current data to predict the most appropriate watering schedules based on important parameters such as evapotranspiration levels, rainfall forecasting, and soil moisture patterns. This predictive model not only enhances water usage to its optimal value but also guards against under- or over- irrigation situations that could compromise plant wellness.

    Remote access and user control are provided by the Blynk IoT mobile app, which provides a graphical interface for visualizing sensor information, managing irrigation hardware, and getting timely alerts. This mobile integration gives end-users the power to monitor field conditions and perform manual overrides when needed, thus minimizing reliance on continuous field presence.

    Experimental deployment and testing validate the effectiveness of the proposed system in minimizing water wastage, enhancing crop health indicators, and facilitating precision agriculture practices. The scalability and modularity of the system also enable it to be used for different types of crops and environments, giving rise to a path toward sustainable smart farming.

  4. LITERATURE SURVEY:

    1. Introduction:

      During the last ten years, agriculture has seen a widespread implementation of intelligent technologies focused on increasing the productivity of crops, the efficient use of resources, and sustainability. The integration of Internet of Things (IoT) and Artificial Intelligence (AI) for irrigation management has been a strategic solution to deal with problems of water scarcity, uneven irrigation, and excessive dependence on human labor. Several research studies within departments of Computer Science, Embedded Systems, and Agricultural Engineering have investigated varying frameworks and architectures. Yet real-time adaptability, high deployment expenses, and limited integration of AI remain existing problems. In this section, literature is reviewed within the related domains critically in order to present gaps in the current research motivating the proposed system.

    2. Literature in Computer Science and Engineering Department:

      The field of Computer Science has greatly contributed to the conceptualization and development of automated irrigation systems employing software-driven architectures, cloud integration, and mobile interfaces.

      • Smith and Patel (2022) proposed an IoT-based smart irrigation model based on rduino and cloud technologies. Their model gathered soil moisture data and regulated irrigation from a central cloud server. Even though the model reduced manual intervention and ensured effective watering, it didn't apply decision- making based on AI and was greatly dependent on continuous internet connectivity, which might prove to be a restrictive factor in rural installations.

      • Kumar and Sharma (2021) had suggested an AI- based smart irrigation system involving supervised machine learning techniques to ascertain irrigation schedules. They integrated real-time weather forecasting for optimal irrigation. The system was, however, not resource-friendly due to its cloud-based computation and lacked compatibility for use on low-power edge devices.

      • Gupta and Reddy (2020) deployed a machine learning-driven decision system combined with soil moisture sensors and wireless microcontrollers. Although the system effectively automated irrigation operations based on sensor readings and data analysis, it did not include user control options like mobile dashboards and did not adopt adaptive threshold tuning according to environmental dynamics.

      • These studies highlight the necessity for solutions that balance computational intelligence with feasibility of deployment,

        especially in low-infrastructure environments.

    3. Literature in Embedded Systems and IoT Field: Literature in the Embedded Systems and IoT field has highlighted low-power, cost-effective solutions that incorporate sensing, actuation, and control systems for automating agriculture.

      • Bouras et al. (2017) discussed the deployment of Software-Defined Networking (SDN) and Network Function Virtualization (NFV) in the 5G environment to facilitate smart agriculture. The paper listed future-oriented infrastructure capabilities but also noted high complexity of implementation and the unviability of such advanced solutions for agricultural development in rural and semi-urban regions.

      • Rao (2021) wrote about several sensor-based platforms for precision farming, such as integrating ESP-based microcontrollers and sensors like DHT11/DHT22. The study was centered around soil parameter monitoring but was missing intelligent control systems that could adjust operations dynamically depending on real-time data as well as environmental fluctuations.

      • Wang (2020) discussed the use of AI in edge computing devices for farm-level applications. The study highlighted the necessity to decentralize intelligence from cloud servers to local devices. Nevertheless, the deployment necessitated sophisticated microcontroller setups and AI libraries that were not completely optimized for ultra-low-cost hardware platforms such as ESP8266.

      • Notwithstanding the advancements achieved, the gap between embedded intelligence and real- time responsiveness and remote control capabilities persists.

    4. Summary of Research Gaps:

      • A thorough review of literature identifies some of the ongoing challenges:

      • Limited Real-Time Adaptability: The majority of systems operate on predetermined schedules or basic threshold logic without reacting to changing environmental conditions.

      • Overdependence on Cloud: Systems based on cloud computing for AI processing have greater latency and need stable internet, which is not always possible.

      • Lack of AI-Based Forecasting: Not many systems incorporate predictive analytics to anticipate and adjust irrigation proactively according to weather patterns.

      • Limited User Interaction Features: Most solutions lack mobile-based platforms for remote monitoring, control, or threshold adjustment.

      • High Cost and Complexity: Sophisticated AI- powered platforms are not affordable for small farmers or individual users.

    5. Relevance to the Proposed Work:

      The IoT-Based Smart AI Plant Irrigation System outlined in this research fills these gaps by providing:

      • Local Decision-Making: Utilizes the ESP8266 microcontroller to control irrigation independently based on soil and environmental conditions without reliance on the cloud.

    7. Integration with Agricultural Marketplaces: Supply Chain Automation: Future releases of the system can be connected to online marketplaces so farmers can automatically plan irrigation cycles according to market demand or projected crop yield. This will make it a more efficient supply chain, as it optimizes irrigation according to market price and demand forecasting.

      Farmer Collaboration Platforms: The platform might enable real-time collaboration among farmers, researchers, and agricultural extension services to exchange insights and best practices, enhancing mutual agricultural results.

    8. Smart Agriculture Ecosystem Integration:

      IoT-based Smart Greenhouses: The irrigation system could be integrated into smart greenhouse environments, where automated systems control not only irrigation but also temperature, humidity, and CO2 levels. This would create a fully autonomous environment for growing plants, further reducing labor costs and improving efficiency.

      Integrated Farm Management Systems: The irrigation system may be a component of an integrated farm management system (IFMS) with modules for pest control, crop rotation, and resource planning, offering a comprehensive approach to farm management.

    9. Commercialization and Adoption in Developing Regions:

      Low-Cost Solutions for Small Farmers: Future innovations might aim to design low-cost, affordable versions of the system that are specific for smallholder farmers in developing nations. This can be done via subsidies, public-private partnerships, or the development of low-cost sensor technology.

      User-Friendly Interfaces for Non-Tech-Savvy Users: With the evolution of the system, making the user interface easier to use and intuitive may facilitate widespread adoption by non-tech-savvy farmers, particularly in rural settings where technology adoption may be sluggish.

    10. Machine Learning-Based Anomaly Detection: Predictive Maintenance: The system may include predictive maintenance using machine learning algorithms to detect possible breakdowns before they happen. By constantly monitoring data from sensors and hardware parts, the system might forecast when equipment such as pumps, valves, or wiring would require maintenance or replacement.

    Data Anomaly Detection: Anomaly detection software could be used to highlight inconsistencies in sensor data that may signal issues with the irrigation system, like pipe clogging or sensor faults, to allow for faster troubleshooting and maintenance.
