Smart Sprinkler System
Abstract
Agriculture consumes the majority of freshwater in the United States, and with growing pressure to conserve water in the agriculture sector, people are looking for newer and better methods in water conservation. The objective of this project is to implement a residential irrigation system that utilizes IoT (Internet of Things) concepts to control and conserve water usage. The irrigation system consists of a microcontroller activates 24 VAC electrical valves to control the water flow of sprinkler devices. The project will consist of using one SJone board that act as an irrigation scheduler that dictates periodic activation of sprinkler devices. The scheduler obtains weather and forecast readings from the internet and use it to make changes (if any) to the scheduling of irrigation events. A relay circuit connected to the SJone board allows the scheduler to turn on/off sprinkler devices. Soil moisture sensors were deployed to local areas to send soil conditions of plants to the scheduler. In a scheduled event, the scheduler check the soil conditions of the local area and determine if it should activate sprinkler devices. The user involvement is to configure the scheduler to activate the sprinkler devices at which specific days and times, but once that is set, the scheduler became automated and acts on its own without requiring additional user’s involvement. The attractive function of the scheduler is that it behaves “smartly” by following a set of predefined rules.to control the irrigation system. For example, on a rainy day, the scheduler will delay or remove a scheduled irrigation event. By having a smart irrigation system in the home, the user will have an easier time saving and conserving water much more efficiently.

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.
User's Schedule Time
9:15 PM
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.
