CHAPTER 101-Wire Weather Station
Introduction
As the chapter’s name implies, I will be showing you how to build a weather station. This station will be quite basic, measuring only temperature, pressure, and humidity, but it may be easily expanded to measure other weather components, such as wind speed and rainfall. All the weather sensors are connected to the RasPi with a very clever interface known as 1-Wire™, which makes it very easy to add additional components.
The RasPi runs on a software package named owfs, short for 1-Wire File System. This open-source software contains every function required to interface the RasPi with all the system components used in this project.
