 Develop sensor network to monitor a home. ◦ Highly customizable ◦ Easily configurable ◦ User friendly  Will be able to monitor many areas of a home wirelessly ◦ Temperature ◦ Open/close doors ◦ Ambient light ◦ Motion  System connects to internet ◦ Allows for external monitoring ◦ Provide alerts via SMS and IM

 Home Heartbeat ◦ Comes in three different packages  Basic ($225)  Whole ($625)  Water($792) ◦ Extra sensors available for custom needs ◦ Need to pay for alerts ◦ Need broadband internet for some alerts and remote access ◦ Have to pay for Eaton broadband service (not internet)

 TattleTale Alarm ◦ Comes with one base station and remote. Sensors sold separately  Price varies depending on location. Roughly $850  Sensor price varies  Most sensors about $150  Some indoor sensors are about $70  Some outdoor sensors are about $400 ◦ Portable alarm system  Designed for construction sites  Some use for home monitoring

 Main reasons why this project is not like all the other home monitoring systems ◦ Highly configurable and robust user interface ◦ Easily extendable through standard interface protocol

 There are two main interfaces for the user ◦ Touch screen display on base station ◦ Web interface accessible by any internet ready device  Full control is granted at touch screen  Limited control is available on web interface to provide security for the monitored area  Notifications are used to alert the proper people

 Types of notifications 1.Instant Message (AIM) 2.Telephone Call 3.Audible Alarm 4.Log event in data log 5.Trigger actuator to move to a predefine position

 System Controller (C#) ◦ Decodes information sent from sensor and takes appropriate action ◦ Sends commands to control modules ◦ Reads user events from database ◦ Monitors Events ◦ Sends commands to alert system ◦ Logs data in database

 Each sensor will be powered by a 3.6V Lithium Ion battery  Each actuator and control module will be powered by a 9v AC/DC converter and a linear 3.3V regulator  Sensor and actuator module will consist of a Xbee module, PIC microcontroller, a power source, and associated sensor.  Sensors have a 133 foot range indoors

 Wireless Contact Sensor

 Wireless Ambient Light Sensor Vo

 Wireless PIR Sensor

 Wireless Temperature Sensor Ta = Ambient Temperature Vout = sensor output voltage V0c = Sensor output Voltage at 0 deg C = 500mV Tc = Temperature coefficient = 10mV/degC

 Wireless General Purpose I/O

 Wireless Servo Module

 Wireless Thermostat

 Wireless Base Station

 Base Station Testing ◦ Database reporting ◦ Adding/Removing Modules ◦ Configuring events/actions ◦ User interface elements  Web Interface / PDA Interface ◦ Monitoring home screen modules ◦ Functionality  XBee ◦ Wireless communication ◦ Adding / Removing nodes ◦ Addressing nodes ◦ Sensor to XBee communication  User Alerts ◦ IM Alerts ◦ SMS Alerts ◦ Audible Alarm ◦ Data Logging ◦ Servo/Actuator Movement

 Integration Testing ◦ Test communication between modules  Adding a module  Removing a module ◦ Test event and alert system  Configure events to deliberately cause an alert  System Testing ◦ Setup system in mock home ◦ Ask sample user to use system  Add or remove modules  Configure events and alerts

Hub and Spoke Strategy  Integration Strategy ◦ Allows for parts to be integrated at separate times ◦ Base station is the Hub ◦ Each system will read and modify data on base station ◦ Don’t have to worry about talking to other systems

 Web/Database Programming ◦ New topic/languages to group  Web interface for PDA  Only have 5 wireless modules – planned on swapping out wireless transceivers with each sensor module.

 Computer Engineering and Computer Science ◦ Programming of Microcontroller ◦ Serial Communications  Electrical Engineering ◦ Wireless Sensors ◦ Sensor interfacing  Information Technology ◦ Touch Interface ◦ Web Interface  Mechanical Engineering ◦ Motor/Servo Controls ◦ Thermostat Controls  Systems Engineering ◦ Planning ◦ Integration
