The Internet of Things (IoT) is a new concept in intelligent automation and intelligent monitoring using the Internet as the communications medium. The “Things” in IoT usually refer to devices that have unique identifiers and are connected to the Internet to exchange information with each other. Such devices usually have sensors and/or actuators that can be used to collect data about their environments and to monitor and control their environments. The collected data can be processed locally or it can be sent to centralized servers or to the cloud for remote storage and processing. For example, a small device at the size of a matchbox can be used to collect data about the temperature, relative humidity and the atmospheric pressure. This data can be sent and stored in the cloud. Anyone with a mobile device can then access and monitor this data at any time and from anywhere on Earth provided there is Internet connectivity. In addition, users can for example, adjust the central heating remotely using their mobile devices and accessing the cloud. This book is written for students, for practising engineers and for hobbyists who want to learn more about the building blocks of an IoT system and also learn how to setup an IoT system using these blocks. Chapter 1 is an introduction to the IoT systems. In Chapter 2, the basic concepts and possible IoT architectures are discussed. The important parts of any IoT system are the sensors and actuators and they are described briefly in Chapter 3. The devices in an IoT system usually communicate with each other and the important aspect of IoT communication is covered in Chapter 4. Chapter 5 proceeds with the features of some of the commonly used development kits. One of these, the Clicker 2 for PIC18FJ manufactured by mikroElektronika, can be used as a processor in IoT systems and its features are described in detail in Chapter 6. A popular microcontroller C language, mikroC Pro for PIC gets introduced in Chapter 7. Chapter 8 covers the use of a click board with the Clicker 2 for PIC18FJ development kit. Similarly, the use of a sensor click board is described as a project in Chapter 9, and an actuator board in Chapter 10. Chapters 11 and 12 cover Bluetooth and Wi-Fi technologies in microcontroller based systems, and the remaining chapters of the book demo the creation of a simple Wi-Fi based IoT system with cloud-based data storage. This book has been written with the assumption that the reader has taken a course on digital logic design and has been exposed to writing programs using at least one high-level programming language. Knowledge of the C programming language will be very useful. Also, familiarity with at least one member of the PIC series of microcontrollers (e.g. PIC16 or PIC18) will be an advantage. The knowledge of assembly language programming is not required because all the projects in the book are based on using the C language. If you are a total beginner in programming you can still access the e-book, but first you are advised to study introductory books on microcontrollers.

Siglent's SDG2000X is a series of dual-channel function/arbitrary waveform generators with specifications of up to 120 MHz maximum bandwidth, 1.2 GSa/s sampling rate and 16-bit vertical resolution. The proprietary TrueArb & EasyPulse techniques help to solve the weaknesses inherent in traditional DDS generators when generating arbitrary, square and pulse waveforms. With advantages above, SDG2000X can provide users with a variety of high fidelity and low jitter signals, which can meet the growing requirements of complex and extensive applications. Kenmerken Dual-channel, 40 MHz bandwidth, 20Vpp maximum output amplitude, high fidelity output with 80dB dynamic range. High-performance sampling system with 1.2GSa/s sampling rate and 16-bit vertical resolution. No detail in your waveforms will be lost. Innovative TrueArb technology, based on a point-by-point architecture, supports any 8pts~8Mpts Arb waveform with a sampling rate in range of 1?Sa/s~75MSa/s. Innovative EasyPulse technology, capable of generating lower jitter Square or Pulse waveforms, brings a wide range and extremely high precision in pulse width and rise/fall times adjustment.

De low-noise labvoeding van Elektor is een volledig analoge, instelbare, symmetrische unit met gemiddeld vermogen, zonder schakelende of digitale componenten. De uitgangsspanning is instelbaar tussen 0 V en ±22 V, en de uitgangsstroom kan worden ingesteld van 0 A tot 1 A. Doordat elke vorm van schakeltechniek wordt vermeden, levert het ontwerp extreem weinig ruis. Voor de weergave van beide uitgangsspanningen en -stromen worden vier kleine analoge paneelmeters met draaispoel gebruikt. De meeste moderne laboratoriumvoedingen en AC-adapters maken gebruik van schakelende technieken. Zelfs de beste uitvoeringen vertonen onvermijdelijk hoogfrequente rimpel en andere schakelartefacten op hun uitgang, die het testen van gevoelige analoge schakelingen kunnen verstoren en metingen van kleine signalen kunnen beïnvloeden. Om dit te voorkomen, is het concept hier een volledig analoge voeding. Hoewel deze minder efficiënt is dan vergelijkbare schakelende voedingen, is de lagere efficiëntie bij gebruik op de testbank nauwelijks van belang en zorgt deze voor schonere en betrouwbaardere meetresultaten. Omdat veel analoge schakelingen een symmetrische voeding vereisen, levert dit ontwerp positieve en negatieve uitgangsspanningen van gelijke grootte. Een kleine hoeveelheid afregeling is beschikbaar om eventuele onbalans te compenseren. Uiteraard is ook een instelbare stroombegrenzing aanwezig. De kit bevat de onderdelen die nodig zijn om de voeding te bouwen, met uitzondering van de transformatoren.
