11. Project Demonstration 1.An ability to detect motion based on temperature variance, noise above 90dB, the presence of smoke/combustion with a photoelectric amplifier, and to measure temperature with a thermocouple amplifier. 2.An ability to encode and transmit data packets wirelessly to/from the remote sensors with a sensor identification address included in each packet. 3.An ability to arm/disarm the security system and to alert the user (visually, audibly, and through email) of emergency conditions from both the CMS and the remote sensor units. 4.An ability to time stamp events and log them in non-volatile memory on the CMS. 5.An ability to display event logs and operational status on an LCD as well as a webpage hosted by an embedded web server.
