Applications and Implications
Assignment
Individual
• propose a final project that integrates the range of units covered, answering:
What will it do?
It is an IOT Smart Farming System that aids in ensuring the proper conditions for plant growth by monitoring the moisture levels, light and temperature levels of the environment. For employment of this project I will be automating the watering system and monitoring the temperature levels for the plants.
Who's done what beforehand?
Automatic irrigation system that uses soil moisture sensors to detect when the soil is dry so that the system can channel water to crops and when enough water has been delivered the system can shut down the water supply. A farmer can also operate the system remotely by sending sms messages to the system that would initiate desire responses such as turn on water pump and open a specified water valve so that water can be channel of a specified portion of land or close a previously open valve and open a different one so that water can be channeled to another portion of land.

What will you design?
1. The plant encasing container that will hold the plants that are grown in the medium.
2. The a larger container to simulate a place where the plants are being grown either a green house or a personal space.
3. The electronics board where sensors and other components will be attached.
What materials and components will be used?
Below are th eresources for the project.
1. Soil Moisture Sensor
2. Temperature Sensor
3. Valve
4. Flow meter
5. Transistor
6. 12V DC battery
7. 5V regulator
8. Board
9. Acrylic sheet 8*4
10. Pipe 1/2
Where will they come from?
All the materials listed above are available online and other I sourced them from our lab inventory.
How much will they cost?
All the materials listed above are available online and other I sourced them from our lab. The cost for all materials is approximately $50.
What parts and systems will be made?
All the parts will be made in our labs;
I will design and fabricate the container for the whole project.
I will also design and fabricate the plant encasing container.
I will also design and fabricate the electronics box for holding the electronics.
What processes will be used?
• Computer-Aided Design - the container, plant encasing, electronics box.
• Computer Controlled Cutting - lasercutting the acrylic material for container and the electronics box.
• Electronic production - fabricating the electronics board.
• 3D Printing - plant encasing and sprinkler
• Electronic design - electronic board for the project
• Input device - Temperature sensor, soil moisture sensor and water flow sensor.
• Output device - selonoid valve
• Embedded programming - programming the board
• Interface and Application Programming - the web interface to view the input devices data.
• Networking and Communications - Wifi module
What tasks need to be completed?
The plant casing
The electronics box
The main container
Populating and programming the board
Connecting everything together both the mechanics and electronics
What questions need to be answered?
Maximizing and preserving the available resources.
The efficiency of the system with no human intervention.
What is the schedule?
Lasercutting, machining and 3D printing - 1 day
Board designing and fabrication - 1 day
programming and debugging - 2 days
Assembling and testing - 1 day
Documentation and uploading online- 1 day
How will it be evaluated?
The tasks will be evaluated based on the completion per specific days outlined.
