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.
