This week I primarily worked on the Introduction, Design Requirements, Architectural Overview and System Description of the design report. I spend the majority of the time thinking through the Software Design of our system and the interfacing between the sensors and the software. 
I also helped with the testing of the PIR sensors during lab.
Next week I plan to work on a lot on testing, and particularly focusing on the microphones, to determine false positives, reasonable thresholds, etc. I hope to also start combining the data from the PIR sensors with the microphone in some preliminary tests.
