first, lets talk about data
NOW, Sensors!
sensor Journalism
Use sensors to build data sets.
Scientist have been doing this stuff for a loooong time. Their equipment is $$$
Arduino!
Very much DIY, garage band, “Maker culture”
Info gathered is readily adapted to existing framework of data journalism,
project genesis
CAR class + Matt Waite
living downtown can get noisy
idea of a sound map slowly developed.
Justin helped flesh out ideas at hacks hackers-
Talked to everyone about it- A proposal was crafted and the Knight Foundation lapproved the idea for a Prototype Grant.
Initial idea: arduino + sound sensor + cell phone card to text the data
our
technology:
First:
arduino + sound sensor
then, + data loggers.
sound sample every second.
renders voltage reading -
data reflects environment.
problems:
power hungry(ish)
manual sd card collection is :(
then, stumbled into world of jeenodes & moteinos
low power, wireless
these are engineered to use minimal power.
operation for year(+) on one battery
designed to work with radio transcievers
settled on moteino for our project-
uno was overkill for our needs
uses same chip in arduino uno
affordable!
comes assembled with radios
surface mount soldering is hard.
