In previous chapters, I discussed several methods you can use to store sensor data. One of those methods is storing the data in a database located on your network. If you recall, this has several advantages, not the least of which is that you do not have to connect your sensor network to the Internet to enable this capability.
This is not difficult to achieve if your sensor nodes are connected to a Raspberry Pi, but how do you do this if your sensor nodes are connected to an Arduino? The Arduino could be a sensor node itself, with one or more sensors ...
