5. Major component analysis Computer platform ◦ Intel Atom board vs Asus wireless router Microcontroller ◦ Freescale MC9S12C vs Microchip PIC18F25K22 Wireless module ◦ MRF24WB0MA Wi-Fi vs WRL-08665 XBee

6. Project-Specific Success Criteria An ability to sense motion based on temperature variance, noise above 90dB, the presence of smoke/combustion with a photoelectric amplifier, and measure temperature with a thermocouple amplifier. An ability to encode and transmit data packets wirelessly from/to the remote sensors with a sensor identification address included in each packet. An ability to arm/disarm the security system and to alert the user (visually, audibly, and through email) of emergency conditions from both the central monitoring station and the remote sensor units. An ability to time stamp events and log them in non-volatile memory on the central monitoring system. An ability to display event logs and operational status on an LCD (as well as a webpage hosted by an embedded web server).
