Abstract

Thus far into our journey of sensor networks, we have discovered how sensor networks can be formed, the type of nodes, and their roles that comprise a sensor network, and we’ve spent some time learning about XBee modules and how to program them with MicroPython.

Notes

  1. 1.

    These are the basic methods. Other methods including using XBee modules to control other devices are possible but are more advanced and beyond the scope of this work.

  2. 2.

    This is a common novice mistake: building the entire sensor network including data collection without testing the individual components. The best method is to build your network in stages after testing each node separately (or in as small a configuration as possible). Debugging a network with many nodes is much harder than building the network with networks that have been assembled in stages.

  3. 3.

  4. 4.

    We leave it as an exercise to module the script to send readings without stopping (e.g., continuously).
