Updated Schedule

•Milestone I•Flash web application TCP/IP connection with Netburner ethernet module•UART connection between Netburner ethernet module and mother Zigbee module•UART connection between child zigbee module and microcontroller.•Temperature sensor interfaced with I2C bus on the Netburner ethernet module.

Updated Schedule• Milestone II

• Entire data flow path is integrated• All hardware on PCBs (i.e. no development boards)• Correct integration of sensors and web display

• Final Design Expo• Integration of all hardware components in a model

house• Proper installation of sensors in the model house• Secure login for website and full control over the

devices in the house
