Automated Plant Control System

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

Design & Implementation

Hardware Design

The hardware design for this projects will be split into the different sections of our project.
The different hardware components include a power circuit and water pump/LED drivers. The
Hardware design will then be followed by the Hardware interfacing components.

Power Circuit
Due to the low power outputs of the LPC1758. in order to drive the LED and the the water pump,
an external power source strong enough to do so is necessary.

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?

Project Video

Upload a video of your project and post the link here.
