Beginning Sensor Networks with Arduino and Raspberry Pi

CHAPTER 4

Raspberry Pi-based Sensor Nodes

Using microcontrollers to host sensors is an economical way to build a sensor network. But what do you do when you need more computational power than a microcontroller can provide? What if you need to convert the data to a different format, incorporate the data in an application, or print a hard copy of the sensor data? In these situations, you likely need a computer that has more processing power, can allow the use of common applications, permits the use of scripting languages, and affords access to peripherals.

Although personal computers are relatively inexpensive, there are distinct disadvantages ...
