Building a Wifi Temperature Node for Journalism

Wireless sensor nodes can help monitor conditions the community, in the next state over, or across the globe. These sensors don't have to be complex or expensive to be useful -- even a simple wireless temperature node can be helpful in tracking heat waves, monitoring the heat-island effect in cities, and serving as a warning system for asthma sufferers.

Previously, I've chosen a prototyping platform and 3D printed useful parts to make a sensor node. This post covers planning, assembling, programming, and testing a wireless temperature sensor node for journalism.

Nodes for journalists: a primer on bringing sensor data to the reporter

Drones are pretty cool, and could be pretty useful for journalists. They allow journalists to film hard-to-reach spots, such as partially-sunken cruise liners. These unmanned systems also can be used to collect geospatial data and photomaps, both of which can come in handy for a journalism investigation.

As I’ve written before, though, drones simply are remotely piloted aircraft (or watercraft). By themselves, they are not very useful tools. What actually makes them useful is that they are mobile platforms for sensors, which can collect data to guide reportage. Cameras are just one of a multitude of sensors that drones can carry into the sky.

What kind of additional sensors could you use on a drone? It’s probably easier to ask what exactly you want to measure in the environment, and then find a sensor to fit the application.
