Sensor nodes need a good home if they're to last any considerable amount of time. And if they're to be deployed outdoors, they need an especially robust home.
This can be complicated. Most sensors need to be exposed to the elements to obtain good readings. But expose these electronics to the elements too much, and you'll break them.
In a pursuit of finding the right balance between price and accuracy for a sensor node for professional and community journalists, I'm fabricating a prototype using open-source hardware and software, 3D printers, and now, lasers. Fortunately the "maker" revolution makes this process more accessible than ever.
Previously I wrote about working with Arduinos and temperature sensors. Continuing on the theme of sensor nodes for journalism, here are some details on the next step in the prototyping process.
