Sensor JournalismLeveraging inexpensive computers, sensors and open source
code to crowdsource community data.
How I heard about it
• Online News Association conference• WNYC public radio• Deployed sensors under chairs in auditorium
The sensors
Body heat
SoundMore talking over here?
CellularMore texting over here?
A growing movement• Air Quality Egg, part of a community-led
sensing network.

Cicada tracker
• WNYC posted instructions to build $80 cicada sensors.
• Everything could be ordered online through Radio Shack.
• Tracked when ground would be at 64 degrees.
• 1,500 participated.

2008 Beijing Olympics• AP deployed air quality sensors around
Beijing. Real-time tracking of air.
Other projects
• Sun Sentinel: sensors on tollgates registered times and radio frequencies emitted by tags on cars driven by police passing through known locations — from which the journalists derived identities, their speeds and concluded they were breaking the law.
Other projects
• The Washington Post’s ShotSpotter: sensed gunshots via sound using air pressure sensors.
• Converted into digital signals, pattern-matched by computersto produce records of the gunshot locations throughout Washington, D.C.
Other projects
• The Houston Chronicle: monitored air quality in neighborhoods bordering factories that regularly emit toxic smoke.
• Public Lab: citizen group that recorded oil levels from Deepwater Horizon spill.
• USA Today “Ghost Factories” : tested soil for contamination at 800 abandoned factories.
Cooking Class monologue
• Demonstration of an Arduino Uno, and configuring and programming it to do a simple light show - Arduino is plugged into the laptop, code is already written, push a button on laptop to transfer program, Arduino blinks to indicate code is ready, then can do "christmas lights" - can change a number in Sketch to have the light show alter - good idea to have some close ups of the Arduino's lights from above
Popular platform: Arduino Uno.• Driving cost down with DIY kits.
To learn more
Low cost
Cost: $29 for the Uno (the computer), $35 Sidekick Basic Kit (wires and sensors).

The next frontier: YOU
• Sensing YOU with YOUR permission.• Apple Watch, Android Wear, Fitbit, Galaxy
Gear, others.• Privacy? Security of personal data? Big future
issues.
Activity
• Read through some of the case studies from Tow Center for Digital Journalism report on sensor journalism.
• Go to Sparkfun.com• Find some sensors.• Come up with a concept for a sensor array
that could tell a story in an interesting way.
