Where to Put It All: Storing Sensor Data
If you have had success with the projects thus far in the book, you have at your disposal several forms of sensor and data-aggregate nodes. In essence, you have the basic building blocks for constructing a sensor network to monitor and record temperature data. It would not take much more work to add nodes for other environmental sensors such as humidity or barometric pressure. Indeed, the basic sensor node you have built can host a variety of sensors.
If you have run the example projects and experimented with the challenges, no doubt you have noticed that a lot of data is being generated. What ...
