All Your Base are Belong to You

Abstract

Security and Home Automation (SHA) is a complete system that will manage home automation and security with the use of Wi-Fi. The system will be a compilation of multiple devices that will work with a microcontroller as the hardware subsystem, in which each device will incorporate one or more components.

Objects & Introduction

This system will automate your security and home functions for a higher quality of life

Security Thermal Sensor

  • Security Thermal Sensor will capture movement and heat from intruders
  • Security Thermal Sensor will send an alarm signal to the server after the thermal value reaches a certain threshold
  • Alarm Signal from the Security Thermal Sensor will be sent to the server through Wi-Fi communication

Raspberry Pi or Receiving Server (server)

  • Server will receive data from the Security Thermal Sensor
  • Server will receive alarm signal and be set to an alarm state until it is deactivated

Team Members & Responsibilities

  • Christopher Cheng
    • Wi-Fi Hardware and Software Design
  • Tyler Gray
    • Raspberry Pi (server) Research and Web UI
  • Prateek Grover
    • Thermal Motion Sensor Hardware and Software Design
