💡Inspiration 

This project was inspired by the real challenges faced by farmers in Egypt, where traditional farming methods are still widely used despite the availability of modern technology. The lack of awareness and access to smart tools often leads to inefficient use of water and resources. Additionally, the increasing global focus on sustainability, water conservation, and smart agriculture encouraged us to explore how IoT technologies can be used to improve farming practices. The idea was also influenced by the need to support local communities and enhance agricultural productivity by bridging the gap between traditional farming and modern smart solutions. My idea was inspired by real agricultural challenges and the need to make farming smarter and more efficient.

📊Assessment Summary 

This impact assessment guided our design decisions by emphasizing affordability, simplicity, and accessibility. As a result, I selected low-cost components such as Arduino and basic sensors to ensure the system is cost-effective for farmers. I also focused on creating a simple and user-friendly interface so that users with limited technical knowledge can use the system easly. Additionally, the design was made scalable to allow future expansion and wider adoption in different agricultural environments. I designed our system based on real user needs, not just technical features. 

3. Project Idea & General Features

 📄 Project Description 

The project is a Smart Farming Assistant system that automatically monitors soil conditions and controls irrigation without human intervention. The system uses a soil moisture sensor connected to an Arduino microcontroller to continuously measure the moisture level of the soil. Based on this data, the system automatically activates or deactivates a water pump using a relay module. When the soil becomes dry, the system turns on the irrigation system, and when the soil reaches an optimal moisture level, it stops watering. This helps reduce water waste, improve crop productivity, and eliminate the need for constant manual monitoring. The system is designed for small and medium-scale farmers who need an affordable, easy-to use, and efficient smart irrigation solution. 

⚙️ How It Works 

Walk through the user experience step by step. What does the user do? What does the project do in response? 

1. The system is placed in the soil, where the moisture sensor continuously measures soil moisture levels.

 2. The sensor sends real-time data to the Arduino microcontroller. 

3. The Arduino analyzes the data and compares it to a predefined threshold.

 4. If the soil is dry, the system sends a signal to the relay module. 

5. The relay activates the water pump, starting irrigation automatically.

 6. As the soil moisture increases, the system keeps monitoring the data.

 7. Once the soil reaches the optimal moisture level, the Arduino turns off the relay. 

8. The water pump stops, preventing over-irrigation. Our system not only monitors the soil, but also takes action automatically to ensure optimal irrigation. 

🎮 Input 

How does the user interact with the project? What sensing or tactile inputs are used?*

 The user interacts with the system indirectly through environmental inputs rather than direct physical controls. The system uses a soil moisture sensor to detect the condition of the soil and automatically control irrigation. Additionally, a PIR sensor detects motion in the surrounding area, providing a layer of security. These inputs allow the system to operate autonomously without requiring continuous user intervention. 

Input Type Component Purpose Sensing Soil Moisture Sensor Detect soil moisture level to control irrigation automatically Sensing PIR Sensor Detect motion for security and protection Environmental Input Soil Condition (Dry/Wet) Determines whether the pump should be turned ON or OFF 

🧠 Brain *What microcontroller or processing unit runs the logic?* 

Device: Arduino UNO

Role: Reads data from the soil moisture sensor and PIR sensor, processes the inputs, and controls the relay to turn the water pump ON or OFF automatically.

🔋 Power Management

Power Source: 9V Battery (for pump) + 5V USB (for Arduino UNO)
Voltage Requirements:

• Arduino: 5V

• Relay Module: 5V

• Sensors (Soil + PIR): 5V

• Water Pump: 6–9V (from battery)

Power switch / management notes:
The Arduino is powered via USB, while the water pump is powered separately using a 9V battery through the relay. This separation ensures safe operation and prevents overloading the Arduino. The relay acts as a switch to control the pump without drawing high current from the microcontroller.

🖨 3D Printing Plan *How will you use the 3D printer ?*

The 3D printer will be used to create custom external parts, including the raised project name on the top cover and sensor holders for precise fitting. PLA material will be used due to its ease of printing, low cost, and environmental friendliness. The design focuses on printing only essential components to reduce time and material usage, while ensuring durability and a clean aesthetic finish.

✂️ Laser Cutting Plan

Laser cutting will be used to fabricate the main enclosure using plywood for strength and durability. All parts will be arranged efficiently (nested) on the sheet to minimize material waste. The design uses simple rectangular panels and interlocking joints to ensure easy assembly and reduce cutting complexity while maintaining structural integrity.

We combined laser cutting for structure and 3D printing for customization to achieve both efficiency and professional design.

🔄 Circular Design & Repairability

The project is designed using a modular approach, allowing individual components such as the Arduino, relay module, water pump, and sensors to be easily replaced or repaired without affecting the entire system.

The enclosure is assembled using detachable parts, making it easy to open, maintain, and reconfigure. Components are clearly arranged and accessible, which simplifies troubleshooting and upgrades.

At the end of its lifecycle, materials such as plywood and PLA can be reused or recycled, reducing environmental impact and supporting sustainable design principles.

🖥 Arduino Programming Plan

The Arduino reads input from the soil moisture sensor to determine the condition of the soil (dry or wet). It also reads input from the PIR sensor to detect motion in the surrounding area.

Based on the soil moisture value, the Arduino decides whether to turn the water pump ON or OFF using the relay module. If the soil is dry, the pump is activated; if the soil is wet, the pump is turned off.

Additionally, if motion is detected by the PIR sensor, the system temporarily stops irrigation and can trigger an alert (LED or buzzer) to enhance security.

The system continuously repeats this process in a loop, allowing real-time monitoring and automatic control.
