Project Modifications1. Main types of sensing are daughter

boards rather than all on one motherboard*Easier to break down piece by piece*Easier to debug

2. We have purchased power supplies rather than building them*For convenience*Time constraints*New allowance in budget

3. Ethernet is on a separate daughter board*Allows for easier debugging and block break down

4. Looking into two different types of Zigbee wireless chips*Allows us to test to see which interfaces better
