This book explains how to build sensor networks with Python and MicroPython using XBee radio modules, Raspberry Pi, and Arduino boards. This revised and updated edition will put all of these technologies together to form a sensor network and show you how to turn your Raspberry Pi into a MySQL database server to save sensor data.
The reader will review the different sensors and sensor networks, including how to build a simple XBee network, walk through building sensor nodes on the XBee, Raspberry Pi, and Arduino and learn how to gather data from various sensor nodes.
The book also examines different ways to store sensor data, including writing to an SD card, sending data to the cloud, and setting up a Raspberry Pi MySQL server to host your data. The reader will learn how to connect to and interact with a MySQL database server directly from an Arduino. Lastly, the book explains how to put it all together by connecting the sensor nodes to the Raspberry Pi database server.
If you want to see how well XBee, Raspberry Pi, and Arduino can get along, especially to create a sensor network, then Beginning Sensor Networks with XBee, Raspberry Pi, and Arduino is precisely the book you need.
- Code your sensor nodes with Python and MicroPython
- Work with new XBee 3 modules
- Host your data on Raspberry Pi
