Notes from this data collection:
room 1 = bed mote 165
room 2 = bed mote 167
room 3 = bed mote 166
hallway = pyramid 200
exp started
2:45 – 2:47 set pager by pyramid (around mote time 3000)
2:47 – 2:52 pager in “far” positions of room 1
2:52 – 2:57 pager in “near” positions of room 1
2:57 – 2:59 set pager by pyramid
2:59 – 3:04 pager in “far” positions of room 2
3:04 – 3:09 pager in “near” positions of room 2
3:09 – 3:11 set pager by pyramid
3:11 – 3:16 pager in “far” positions of room 3
3:16 – 3:21 pager in “near” positions of room 3
3:21 – 3:23 set pager by pyramid
3:23 – 3:33 pager in hallway, out of rooms
3:33 – 3:35 set pager by pyramid
From the data collected:
In Room 1 from: 3214-3777
In Room 2 from: 3921-4507
In Room 3 from: 4658-5233
In Hallway from: 5287-5892
Analysis:
From this graph, we see a clear distinction when the pager was in room one. There are a few data points that are lower, but for the most part, it was clear that the pager was in room one from times 3214-3777.
Between the times that the pager was in the rooms, we see much higher RSSI values. However, there seems to be some odd values when the pager was in the hallway (at the end of the experiment).
Among the rooms, room three also has a clear distinction, but things get messy with the hallway signals.
From this graph, we see almost no distinction from in the hallway/ in the rooms.
