Smart Pet Sitter
Hello, Everyone
Today, I will talk about Smart Pet Sitter for senior design.
My name is Hwandong Joo
Designed by Hwandong Joo

2. Project Description
This product is a IoT(Internet of Things) device that help people raise pet easily.
It makes people care and monitor their pet whenever people is outside.
It dispense pet food automatically whenever people wants.
In addition, this product can give a warning to user when their pet barks.
I want to descript my project.
Read all senetence.

3. The Features Can connect to wireless internet
Can control by Smartphone
Can monitor quantity of food in this product
Can observe a pet by camera.
Give warning to people when the food is not enough
Give warning to people when the pet barks
The features of my project is like this

4. Diagram
The diagram looks like this

5. Microcontroller It receive commands from wireless internet by user.
It works a serve motor for feed the food.
It receive data from sensors and send the result to user
It will be Arduino or Raspberry pi with Wi-Fi modular
The microcontroller acts like a brain.

6. Sensors & Parts
Weight Sensor : Check how many food is left in the product.
Microphone & Speaker : Check if the pet barks or not and play sound
Camera : Record the video
Serve Motor : Feed the foods
Power Supply: give power
I plan to use 4 sensors: weight sensor / sound / camera / serve moter / power supply

7. Project Cost Estimate

8. Product Concept Executive Summary Product Users
This project makes IoT product for pet. This product can feed food to pet and monitor them. In addition, the user can control all of features by wireless internet.
Product Users
The people that raise the pet at home or apartment. Also, the animal shelter can use it.
User Accessible Features
IoT connection
Monitoring by camera and sound sensor
Automatically feed food and check the quantity of foods

9. Engineering Requirements
Features
Allows people to monitor their pet by camera
Can do by using any devices that can connect to internet.
Can feed foods automatically
Functions
Feed food and check how many food is left
Monitoring the pet

10. Engineering Requirements
Specifications
Easy to install
Easy to use
Check the pet real-time
User Interfaces
Can use it through wireless internet
Can check how many food is left
Can receive warning when the pet make sounds

11. Architectural Design
The power supply will power the microcontroller and the microcontroller will power the other parts. I do not choose a Arduino or Raspberry Pi for a microcontroller, so I will test both of them and choose one. The microcontroller will receive the everything from weight sensor, camera, and others and send it to user by using wireless services. Also, it will control the serve motor for feeding foods.

12. Functional Elements Serve Motor : Control amount of food feed
Weight Sensor : Check amount of food left
Microphone & Speaker : Check pet is barking or not and play sound when they bark
Camera : Take a video or picture
Microcontroller : Control all parts and Send result to a user.

13. Hardware - Schematics
This product has six parts; Microcontroller, Power supply, Serve Motor, Weight Sensor, Camera, Speaker, and Microphone.

14. Theory of operation
The power supply will give power to the microcontroller.
The microcontroller will receive signal from other parts and send the signal to user through Wi-Fi module.
The serve motor will control the amount of food. It will controlled by microcontroller.
The weight sensor will check how much food are left and send signal to microcontroller.
The camera will take a video and send it to microcontroller.
The sound sensor will catch a sound, and send a signal to microcontroller
The speaker will receive a signal from microcontroller and play sounds.

15. Example detailed Schematics

16. Software Design
The microcontroller is a head of body. It receive signal from all sensor and control serve motor. In addition, It communicates with user through electric device that can connect wireless internet.

17. Product Test Plan For User interface
How much food can user control to feed?
What time interval between feed time can user set?
How can user monitor their pet by camera?
How can user check whether their pet is barking or not?

18. Risk Analysis & Mitigation Plan
