This chapter is focused on the basic concepts of sensors for the Internet of things (IoT). There is a wide variety of sensors, so to better manage them some type of classification will first be necessary. Then, the main characteristics of the sensors will be defined. Understanding these features will undoubtedly help in selecting the most suitable sensor for IoT applications. Finally, examples of commercial sensors particularly suitable for IoT applications are provided.
