Elektor Digital Raspberry Pi 3 – Basic to Advanced Projects (E-book)
This book is about the Raspberry Pi 3 computer and its use in various control and monitoring applications. The book explains in simple terms and with tested and working example projects, how to configure the Raspberry Pi 3 computer, how to install and use the Linux operating system, and how to write hardware based applications programs using the Python programming language. The nice feature of this book is that it covers many Raspberry Pi 3 based hardware projects using the latest hardware modules such as the Sense HAT, Swiss Pi, MotoPi, Camera module, and many other state of the art analog and digital sensors. An important feature of the Raspberry Pi 3 is that it contains on-board Bluetooth and Wi-Fi modules. Example projects are given in the book on using the Wi-Fi and the Bluetooth modules to show how real-data can be sent to the Cloud using the Wi-Fi module, and also how to communicate with an Android based mobile phone using the Bluetooth module. The book is ideal for self-study, and is intended for electronic/electrical engineering students, practising engineers, research students, and for hobbyists. It is recommended that the book should be followed in the given Chapter order. Over 30 projects are given in the book. All the projects in the book are based on the Python programming language and they have been fully tested. Full program listings of every project are given in the book with comments and full descriptions. Experienced programmers should find it easy to modify and update the programs to suit their needs. The following sub-headings are given for each project to make it as easy as possible for the readers to follow the projects: Project title Description Aim of the project Raspberry Pi type Block diagram Circuit diagram Program listing

Elektor Special: Sensoren für Wetter und Umwelt
Bauen Sie Ihre perfekte Wetterstation oder forschen Sie zusammen mit der ganzen Welt an Umweltdaten. Mit vielen praktischen Projekten für Arduino, Raspberry Pi, NodeMCU, ESP32 und weiteren Developmentboards. Wetterstationen erfreuen sich seit Jahrzehnten großer Beliebtheit. Ob in aktuellen oder längst eingestellten Elektronik-Magazinen – regelmäßig finden sich Beiträge zum Eigenbau einer Wetterstation. Im Laufe der Jahre wurden diese Systeme immer ausgefeilter und können heute nahtlos in das Smart Home integriert werden. Allerdings erfordert dies oft die Bindung an einen (teuren) Markenhersteller, der sämtliche Komponenten abdeckt. Mit Ihrer eigenen Wetterstation können Sie jedoch mühelos mithalten – und sogar Messwerte erfassen, die kommerzielle Geräte nicht bieten. Dabei kommt der Spaß nicht zu kurz: Sie erweitern spielerisch Ihr Wissen über Elektronik, moderne Mikrocontroller-Developmentboards und Programmiersprachen. Schon für weniger als zehn Euro können Sie erste Umweltdaten erfassen und Ihr System Schritt für Schritt mit wachsendem Interesse weiter ausbauen. Aus dem Inhalt: Wind und Wetter auf der Spur Wetterdisplay mit OpenWeatherMap und Vakuum-Fluoreszenzanzeige Flüchtige organische Verbindungen in der Atemluft Mit MQ-Sensoren arbeiten: Kohlenmonoxid messen – geruchlos aber extrem giftig CO2-Ampel mit ThingSpeak-IoT-Anbindung Ein Gießautomat für Ihre Pflanzen Gutes Raumklima: Temperatur und Luftfeuchtigkeit sind wichtige Kriterien Schickes Thermometer mit alter Röhrentechnik Nostalgisches Wetterhäuschen für die ganze Familie Luftdruck und Temperatur genau messen Sonnenbrand-Warngerät DIY-Sensor für die Sonnenscheindauer Das Smartphone zeigt’s an: Nebel oder klare Sicht? Erdbeben erkennen Pegelstände von Gewässern und Behältern pH-Wert von Gewässern bestimmen Radioaktive Strahlung erkennen Mit GPS wissen Sie weltweit, wo ihr Sensor ist Logdateien mit Zeitstempel auf SD-Karten speichern LoRaWAN, The Things Network und ThingSpeak LoRaWAN-Gateway für TTN betreiben Mega-Display mit Wettervorhersage
