Designed by Hwandong Joo 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

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.

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

Diagram The diagram looks like this

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.

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

Project Cost Estimate

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

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

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

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.

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.

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

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.

Example detailed Schematics

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.

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?

Risk Analysis & Mitigation Plan
