II. BACKGROUND AND PROBLEM STATEMENT

Conventional irrigation systems common in agriculture, landscaping and residential lawn care struggle with inherent inefficiencies that compromise their effectiveness and sustainability. The biggest of these challenges is their tendency to overwater, often due to indiscriminate application methods. This not only increases water shortage but also burdens users with increased water bills. Additionally, these systems rely heavily on manual times and operations, which contributes to labor-intensive maintenance routines. Manual adjustments, often prone to human error, lead to suboptimal watering practices that can harm plant health. In addition, the lack of adaptation to changing environmental conditions further reduces the efficiency of traditional irrigation systems, as they struggle to adjust irrigation schedules based on factors such as weather forecasts. These systems also lack advanced features such as obstacle detection, which makes them vulnerable to operational inefficiencies and potential damage to plants and infrastructure.

Addressing these challenges requires constantly updated irrigation solutions that use advanced technology to optimize water., reduces dependence on work and improves adaptability. The development of Smart Automated Liquid Sprinkler (SALS) systems represents a significant change to solving these problems.

Through an innovative approach, SALS aims to usher in a new era of optimized irrigation practices, promoting healthier plants, a greener environment, and a sustainable water supply for future generations.

Traditional irrigation systems have several inefficiencies, such as excessive water use, labor-intensive maintenance, and limited adaptability to changing environmental conditions. Reliance on manual interventions often results in suboptimal irrigations and potential damage to plants and territory. Additionally, the lack of automation and advanced features such as obstacle detection led to inefficient operations and increased maintenance requirements. These shortcomings underline the urgent need for an updated solution that can optimize the use of water, minimize manual work, improve adaptability, and ensure efficient and harmless irrigation practices to improve plant care and environmental sustainability.

This includes designing the robot chassis to accommodate the various components, selecting appropriate fluid pump motors and sprinklers for efficient water distribution, and configuring the Arduino boards to optimize performance. In addition, power supplies and driver modules are included to ensure reliable and efficient system operation.

On the software side, SALS relies on advanced programming of Arduino microcontrollers to enable real-time decision making and control. This requires the development of algorithms to process sensor data, plan irrigation cycles according to environmental conditions and dynamically adjust system operation as needed. In addition, a user-friendly web interface has been developed to provide farmers with convenient access to real-time information and control functions to monitor and control irrigation.

B. Integration of IoT Technology:

The integration of IoT technology into the Smart Automated Liquid Sprinkler (SALS) project increases its capabilities in precision agriculture. This section presents the main components and functions that IoT integration enables. IoT-compatible temperature sensor is integrated into the SALS system to monitor the ambient temperature in real time. This information is important for adjusting watering schedules and optimizing water based on temperature fluctuations.

The SALS system includes IoT-based humidity sensors that measure the moisture content of the air, providing valuable insights into environmental conditions for precise irrigation planning and water management. Additionally, IoT-based liquid surface level sensors monitor water and fertilizer levels in storage tanks in real-time, ensuring efficient resource management to prevent shortages or overflows. The system also integrates ultrasonic sensors and servo motors for obstacle detection and avoidance, allowing the sprinkler robot to dynamically adjust its trajectory to avoid collisions. Moreover, the control of the robot's wheels is facilitated by the L298N driver, enhancing its maneuverability and responsiveness to environmental changes.

C. Obstacle Detection and Avoidance Features:

The Intelligent Automated Liquid Sprinkler (SALS) is equipped with advanced obstacle detection and avoidance functions designed for safe and efficient operation in agricultural environments. This system uses a complex approach, combining ultrasonic sensors and servomotors to navigate fields while avoiding obstacles. The SALS system using IoT technology first assesses the presence of obstacles in its path using ultrasonic sensors. Initially, the servo motor maintains a stable position while the ultrasonic sensor searches for obstacles ahead. When an obstacle is detected, the servomotor dynamically adjusts its position, allowing the sensor to search for obstacles on both the left and right sides.

When an obstacle is detected, the SALS system makes a strategic maneuver to avoid the obstacle. It moves back a certain distance and then turns in a direction where no obstacles are detected. This proactive approach ensures that the system can effectively navigate around obstacles, minimizing the risk of collision and damage to both the robot and the surrounding vegetation. Using this intelligent obstacle detection and avoidance strategy, the Intelligent Automated Liquid Sprinkler (SALS) improves operational efficiency and reduces the need for manual intervention. Farmers can use the system in their fields with confidence, knowing that it can independently navigate difficult terrain ensuring uninterrupted irrigation operations.

D. Deep Learning Model for Rainfall Prediction

The system implements the Deep Learning Model for Rainfall, which uses a long-short-term memory (LSTM) neural network architecture. LSTMs are a type of recurrent neural network (RNN) designed to capture long-term dependencies in sequential data, making them well suited for predicting time series such as rainfall. Unlike traditional networks, LSTM have memory cells that can store information over time, allowing them to efficiently store and use past observations. This architecture allows the model to capture the complex temporal patterns of historical precipitation data, facilitating accurate and reliable forecasts. To train the LSTM model, historical rainfall data is obtained from a dataset containing monthly average rainfall for specific regions, for example "COASTAL ANDHRA PRADESH". Each record contains precipitation data for different months over several years, providing a comprehensive historical perspective. The dataset is preprocessed and normalized with Min-Max scaling to ensure consistent and stable training. This preprocessing step is necessary to improve model efficiency by standardizing the input data.

The LSTM model architecture contains multiple layers, including LSTM layers with many neurons, followed by densely connected layers. These layers are designed to capture and learn complex patterns and relationships in precipitation data. In addition, drop layers are included in the model to avoid overfitting, a common problem in deep learning models where the model remembers too much training data and cannot generalize well to unseen data. By applying dropout regularization, the model becomes more reliable and can make accurate predictions on unseen data. After training, the LSTM model is equipped to make rainfall forecasts for the coming months based on user input (e.g. desired year and month). The model uses patterns and relationships learned from historical data to make predictions, providing valuable information for agricultural decision-making. The forecast rainfall amounts are then scaled back to their original range using the Min-Max scale inverse conversion function, providing interpretable forecasts in millimeters. Overall, the deep learning model for rainfall demonstrates the system's ability to use advanced machine learning techniques to provide accurate and actionable forecasts that promote resource management and sustainable agricultural practices.
