The graphs below below are the results the ambience database.
The idea is to identify any notable differences between the measurements the pi’s in two different room: my bedroom, and the living room. I’ve limited the results to those metrics which are of interest. For a comprehensive and more interactive version of this report click here
Temperature
Depending on the season, some of you might be asking: Does it really
get above 40 (104 degrees Fahrenheit) in your bedroom???
No. The sensor is attached to a raspberry pi, which produces a good
amount of heat on its own. The above data measures temperature with a
consistent bias.
Humidity
Pressure
Acceleration [z]
Note: This should be measuring the vertical acceleration,
i.e. gravity.
Unless something changes, there’s notable variability around the value
of 1 in the living room. The Bedroom value holds steady around .985
G’s.
Taken at face value, it means that
- Gravity’s effect is slightly lesser in my bedroom than in the rest of the world, and
- Gravity’s value occasionally jumps .06 G’s in my living room.
I’ll chalk these differences up to measurement error.
A couple of notes:
- What gives with the delay between the date this report is rendered
vs. what is displayed above?
- If the data were immediate, it would be entirely too clear when I was out of town–information I’m not keen to share.
- There are notable gaps in data. Why?
- Some days the DAG fails for no discernible reason–you might take it up with Apache.
- Sometimes, the device itself simply fails to record. ¯\_(ツ)_/¯
