Sensor networks in theory and practice

The book provides an important foundation for understanding the Internet of Things by offering insight into common networking protocols from the microcontroller world and introducing important sensors and other devices, as well as their use and programming. All concepts shown are illustrated with practical circuit and programming examples from the authors' many years of experience. In addition, open libraries for controlling the devices presented in the book are available for readers to download from the publisher's home page. The second edition includes some new devices, especially in the area of networks, a more detailed description of the operating principles of some sensors as well as further tips and tricks for programming. Content - Short introduction to C - Structure and programming of AVR controllers - Important programming concepts - Communication interfaces UART, SPI, I²C (TWI), CAN, Modbus, Bluetooth, ZigBee, and other ISM band techniques - Sensor technology (pressure/temperature/humidity/brightness/acceleration/particles etc.) - Programmable devices (Flash, Clock, Radio, Portexpander) Target groups - Students at technical schools, colleges and universities - Development engineers in embedded systems projects - Ambitious hobbyists and scientists who want to realize their own observation and measurement projects Authors Ansgar Meroth, who holds a doctorate in electrical engineering, has been working as a professor of computer science and information systems in the automobile at Heilbronn University since 2003, having previously spent seven years in development at a major automotive supplier. Petre Sora, Master of Science in Electronics, worked as an electronics developer before taking a position as a research assistant in the field of electronics, hardware-related programming at Heilbronn University in 2002. This book is a translation of an original German edition. The translation was done with the help of artificial intelligence (machine translation by the service DeepL.com). A subsequent human revision was done primarily in terms of content, so that the book will read stylistically differently from a conventional translation.
