My project addresses the sustainability-related problem of water conservation in agriculture.
By using a soil moisture sensor to automate irrigation, I can ensure that plants receive the right amount of water, reducing water waste and promoting efficient water use.
I inspired by the need to create more sustainable agricultural practices because we have a fruit farm behind the house, but I noticed that my father waters it every little while, so I thought about the project.
This project aligns with several Sustainable Development Goals (SDGs):
SDG 6: Clean Water and Sanitation: Ensuring the availability and sustainable management of water.
SDG 11: Sustainable Cities and Communities: Promoting sustainable practices in urban and rural areas.
SDG 12: Responsible Consumption and Production: Reducing waste and promoting efficient use of resources.
Explain your impact assessment on those four pillars: social, economic, environmental, and natural resources. And, explain how this assessment will influence your project concept and goals.
Social Impact:
1- Does your prototype directly address a specific need or improve the quality of life for its target audience?
2- Have you considered inclusivity or accessibility to ensure your solution benefits a diverse group of people?
Economic Impact:
1- Is your prototype designed to be affordable and cost-effective for its intended users?
2- Does your project contribute to local economic growth, such as supporting local manufacturing or jobs?
Environmental Impact:
1- Have you taken/going to take steps to use materials efficiently, reduce waste during production, or repurpose leftover materials from your prototype?
2- Does your solution promote environmental awareness or encourage sustainable practices in its intended use?
Natural Resources Impact:
1- Are you going to responsibly use sourced or recyclable materials in your prototype?
2- Does your solution help conserve essential natural resources like water or energy?
Social Impact
Improves crop yields by ensuring optimal watering, reduces labor for farmers, and promotes sustainable farming practices.
Economic Impact
Reduces water and labor costs over time.
Environmental Impact
Prevents over-irrigation, which can lead to soil erosion and nutrient loss.
Impact on Natural Resources
Reduction in water usage, preserving local water bodies.
Impact Assessment Diagram
Help me that when I design, I will take into consideration the size of the manufactured unit, because I will need to save on the resources used, such as wood, because it comes from trees, and this will allow us to preserve the environment more. Also, the electronic components can be reused, so this will help us achieve sustainability.
How It Works:
The operating scenario is as follows: As soon as we supply power to the control unit, the screen will light up and give a welcome message to the user. The brain will start sending to the sensor if the soil is dry and analyze the signal that will be traced. Then it will turn on the pump if the plant needs water during irrigation. The brain will calculate the percentage of moisture in the soil and then compare until we reach it. For the desired value of this soil, and as for the screen, it will show the moisture percentage of the soil and also the pump Is it working or not? When we disconnect the pump, it appears that it has stopped.
Features:
Soil Moisture Sensor: Measures the moisture level in the soil.
Microcontroller: Processes the sensor data and controls the water pump.
Water Pump: Delivers water to the plants when needed.
LCD Screen: Displays a welcome message and the current soil moisture level.
Power Supply: Provides power to the entire system.
Construction Parts
The design will be a box with a control unit.
Designed the box dimension to contain electrical components such the motor, the Arduino board, the sensor.
The box will have holes for wires of sensors
Input
(Sensing, Tactile Input, and/or Graphical Input)
Soil Moisture Sensor: Measures the soil moisture.
Action
(Physical and/or Graphic)
Pumps : When the sensor senses that the soil is dry, it sends the pump to open so that the plant is watered
Brain
Arduino UNO
Power Management
Battery - 9v
Describe how your project will leverage maker tools like laser cutters or 3D printers to reduce waste, and increase maintainability. Also, explain your choice of materials such as fabric, plastic filament, or recycled plastic sheets to support green innovation. Select materials with low environmental impact, and explain their relevance to your project.
I will start designing my project so that I can build the box out of wood after cutting it on a laser machine.
I will need to do a 3D printing machine of some parts of the project so that we reduce the amount of water lost while watering the plant.
The materials I'm using for the building are wood and pla filament.
As for the wood used, it will be as little as possible, and this will be achieved by designing and then cutting on a laser machine.
As for the electrical components, if there is a malfunction, they can be repaired, or we can replace a part and have them work again, thus serving the project’s sustainability vision.
I'm concentrating on several elements, such as waste reduction, production convenience, and maintainability.
Minimum Features: are the least amount of features that would demonstrate the coverage of all the technical modules and their complete integration
Complete Features: are the set of features that will complete your original project objective and vision
Nice-to-have Features: are the extra set of features that will make the project cooler, yet they need extra time, effort, and/or resources to finish
Minimum User Features
Pumping water when the sensor sends the soil dry and the plant needs water
Action: Water Pumping
Sensing: Soil Moisture Sensor.
Complete User Features
Using the keyboard, the user can adjust the humidity required for the plant.
The pump will then work until the humidity reaches the percentage specified by the user. How will I use it? I will program it with the Arduino and also the humidity sensor with a code so that it performs the function.
Action: Watering the plant to bring the soil moisture content to the user's desire
Sensing: Humidity sensor
User Input: Soil moisture percentage.
Nice-to-have User Features
We use a method to determine whether the plant is sick or in need of spraying for worms or any disease.
Action: The name of the disease or worm appears on the LCD screen
Sensing: Disease sensor
Describe how you’ll use Arduino programming, along with sensors and actuators, to create functions that improve your project’s efficiency, reduce resource use, or monitor environmental impact.
My use of the Arduino will reduce the amount of water lost and will also help in agricultural sustainability, as we reduce the percentage of carbon dioxide by watering the plant with the least amount of water and obtaining the oxygen it needs from the plant after completing the process of photosynthesis.
Sensors are used to determine the humidity of the soil and the atmosphere, and through them music is played and the music, its speed and frequency are changed according to the humidity.
