  2. Presentation Contents • Project Overview • Similar Products • User Interface • System Architecture • Wireless Modules • Testing and Integration • Problem Areas • Multidisciplinary Aspects • Cost

  3. Project Overview • 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

  4. Project Overview

  5. Similar Products • 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)

  6. Similar Products • 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

  7. Similar Products • 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

  8. User Interface • 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

  9. User Interface • Types of notifications • Instant Message (AIM) • Telephone Call • Audible Alarm • Log event in data log • Trigger actuator to move to a predefine position

  10. System Architecture Billy

  11. System Architecture • FlexPHPDatabase

  12. System Architecture • Database

  13. System Architecture • 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

  14. Wireless Modules

  15. Wireless Modules • 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

  16. Wireless Modules • Wireless Contact Sensor

  17. Wireless Modules • Wireless Ambient Light Sensor Vo

  18. Wireless Modules • Wireless PIR Sensor

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

  20. Wireless Modules • Wireless General Purpose I/O

  21. Wireless Modules • Wireless Servo Module

  22. Wireless Modules • Wireless Thermostat

  23. Wireless Modules • Wireless Base Station

  24. Testing and Integration • 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

  25. Testing and Integration • 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

  26. Testing and Integration • 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 Hub and Spoke Strategy

  27. Problem Areas • 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.

  28. Multidisciplinary Aspects • 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
