Abstract

The Plant Control project introduces a plant incubator which allows for resource and energy efficiency while producing healthy flowering and vegetation. The incubator will utilize an SJOne development board, its on-board sensors (light/temperature), a moisture sensor, and LEDs in order to autonomously provide the optimal moisture level for growth in any lighting. The owner of the plant control system can be confident that his or her plant is growing in perfect conditions and will be notified otherwise via an LCD screen.

Objectives & Introduction

This project is a self watering, self lighting, and temperature alerting plant grower.
The entire system is controlled via an SJOne Board which utilizes an LPC1758 Microprocessor.

In addition to the onboard sensors, the project will require interfacing to:

• RGB LCD Screen
  
• Moisture Sensor
  
• Water Pump
  
• PWM controlled LED
  

Team Members & Responsibilities

• Moises Negrete
  • LED and Water Pump Driver Circuit Design
  • Temperature, Light Sensor, PWM software
  • Design and Build Planter
• Eduardo Lemus
  • LCD Interface
  • Source Code Task and Timing Cleanup
• David Chiu
  • Moisture Sensor Interface
  • Power Regulator Circuit
  • Design and Build Planter

Schedule

Show a simple table or figures that show your scheduled as planned before you started working on the project. Then in another table column, write down the actual schedule so that readers can see the planned vs. actual goals. The point of the schedule is for readers to assess how to pace themselves if they are doing a similar project.

Week#	Date	Task	Actual
1	10/24	Research best lighting, temperature, moisture conditions	Completed
2	10/30	Purchase necessary equipment, and begin testing equipment (sensors)	Completed
3	11/06	Interface Sensors	Completed
4	11/13	Interface LEDs and Water Pump	Completed
5	11/20	Begin Building Planter	Completed
6	11/27	Finish Building Planter & Begin RT Code	Completed

Design & Implementation

The design section can go over your hardware and software design. Organize this section using sub-sections that go over your design and implementation.

Hardware Design

Discuss your hardware design here. Show detailed schematics, and the interface here.

Hardware Interface

In this section, you can describe how your hardware communicates, such as which BUSes used. You can discuss your driver implementation here, such that the Software Design section is isolated to talk about high level workings rather than inner working of your project.

Software Design

Show your software design. For example, if you are designing an MP3 Player, show the tasks that you are using, and what they are doing at a high level. Do not show the details of the code. For example, do not show exact code, but you may show psuedocode and fragments of code. Keep in mind that you are showing DESIGN of your software, not the inner workings of it.

Implementation

This section includes implementation, but again, not the details, just the high level. For example, you can list the steps it takes to communicate over a sensor, or the steps needed to write a page of memory onto SPI Flash. You can include sub-sections for each of your component implementation.

Testing & Technical Challenges

Describe the challenges of your project. What advise would you give yourself or someone else if your project can be started from scratch again? Make a smooth transition to testing section and described what it took to test your project.

Include sub-sections that list out a problem and solution, such as:

My Issue #1

Discuss the issue and resolution.

Conclusion

Conclude your project here. You can recap your testing and problems. You should address the "so what" part here to indicate what you ultimately learnt from this project. How has this project increased your knowledge?
