Real World Instrumentation with Python

The Systems

The types of instrumentation systems we will examine might be utilized for laboratory research, or they might be used in industrial settings. An instrumentation system might be used in an electronics lab, in a wind tunnel, or to collect meteorological data. The systems may be as simple as a temperature data logger or as complex as a thermal vacuum chamber control system.

Generally, just about anything that can be interfaced to a PC is a potential candidate for the techniques described in this book. There are, of course, some devices with closed proprietary interfaces, but I will not address those, nor will I delve into complex data collection and process control scenarios such as oil refineries, nuclear power plants, or robotic spacecraft. Systems in those domains are usually best served with sophisticated and complex custom control hardware, and equally sophisticated and complex software. I will focus instead on those instruments, devices, and systems that can be easily programmed using any of a number of common interface methods.
