Introduction
The world’s population depends on agriculture, a crucial industry that faces several obstacles such as resource shortages, climate change, and rising food demand. The demands of a growing population can no longer be addressed by traditional farming systems, which are typified by inefficiencies in crop management and water utilization. Innovative approaches that use technology to improve agricultural operations are therefore desperately needed.
By creating an IoT-powered smart irrigation system, this project sought to overcome these issues. This initiative is significant because it has the potential to transform agricultural practices by implementing resource-saving and productivity-boosting precision farming techniques. The main goals were to create a system that minimizes water waste, enhances plant health, and continuously monitors soil and environmental conditions. The project aims to support the worldwide movement toward sustainability and food security by incorporating IoT into agriculture.
In order to investigate the relationship between environmental sustainability and STEM education, the students chose this project. They sought to create a working prototype through practical experience that would not only solve a pressing problem but also act as a template for integrating technology into practical uses. The project supports the Sustainable Development Goals (SDGs) of the UN, especially those pertaining to climate action, clean water, and responsible consumption.
Research and Background
About 70% of the freshwater resources in the world are used by the agricultural sector, and excessive irrigation and poor water management techniques are to blame for large losses. These inefficiencies make water scarcity worse, which is becoming a bigger problem in dry areas and nations that are experiencing droughts brought on by climate change. According to research, conventional irrigation systems frequently lack the accuracy needed to maximize water use, resulting in resource waste and lower crop yields.
Relevant research emphasizes how IoT can be used to gather data on temperature, humidity, and soil moisture in real time. Algorithm processing of this data can enhance crop yields, lower water consumption, and direct irrigation decisions. The system’s design was also influenced by theories from environmental science and engineering, guaranteeing that it satisfied usability and sustainability standards.
Innovative answers to these problems are provided by emerging technologies, especially the Internet of Things. Farmers can gain valuable insights from real-time data collection and analysis made possible by IoT. IoT systems can direct irrigation schedules by tracking important variables like soil moisture, temperature, and humidity, guaranteeing that water is only applied when and where it is required. IoT-based precision farming has been shown in studies to improve crop output and health while reducing water use by up to 50%.
This project’s design was influenced by theories from computer science, engineering, and environmental science. The project was based on the idea of precision agriculture, which stresses the use of technology to maximize farming methods. Furthermore, the selection of materials and techniques was guided by the principles of sustainable development, guaranteeing that the system is in line with the objectives of both economic and environmental sustainability. This background study emphasized the possible effects of incorporating IoT into agriculture and offered a strong framework for creating the smart irrigation system.

• Software: Python for data analysis and visualization, and a cloud-based IoT platform for real-time monitoring and data storage.
3- Development: The development phase involved integrating the sensors with the Arduino microcontroller and programming the system to collect and transmit data. The microcontroller was programmed to send sensor data to the IoT platform at regular intervals. The irrigation system was designed using a solenoid valve, which was controlled by the microcontroller based on predefined soil moisture thresholds. The system was housed in a waterproof enclosure to protect the electronics from environmental factors.
4- Testing and Validation: The system was tested in a controlled environment to validate its accuracy and reliability. Sensors were calibrated to ensure precise readings, and the responsiveness of the irrigation system was evaluated under various soil conditions. Data collected during the tests was analyzed to assess the system’s performance and to identify areas for improvement. The testing phase also included stress tests to evaluate the durability and scalability of the system.
