“…Az áramkör megépítéséhez mindössze egy ESP8266-os Wifi modulra és 3 darab 4 számjegyű, 7 szegmenses kijelzőre volt szükségem és 3 darab I2C [4] hátlapra, valamint egy USB-micro USB kábelre, amivel az áramforráshoz lehet kapcsolni a Wifi modult. 4. ábra ESP8266 block diagramm [10] Mindenek előtt az ESP8266 module PIN kiosztását kellett tanulmányozni a kapcsolás megtervezése érdekében, mivel rendkívül sokoldalú eszköz, számtalan felhasználási lehetőséggel.…”

Modern világunkban az információ gyors áramlása elengedhetetlen a vállalatok számára. Egyre több embernek jelent sokat a népszerűség. Számos cég és vállalat indított web lapot vagy csatornát a közösségi oldalakon, ismeretterjesztő, oktatási, kutatási vagy jobb kommunikáció céljából. A fentiek figyelembe vétele mellett került megtervezésre, egy hálózatba csatolt „Social Network” számláló, melynek révén aktuális értéket kaphatunk az éppen feliratkozott követők számáról. Az eszköz automatikusan frissíti az aktuális követők, feliratkozók számát, így mindig a friss adatokat mutatja.

“…The wake‐up (WAKE#) signals allow the wake‐up devices to assert an interrupt event to switch the ACPI state controller into the S5 state from the Deep S5 state. The wake‐up conditions are programmable through the system management bus and are recognised in the internal battery powered SRAM [31].…”

Most previous low-power personal computer designs have been either focused on power efficiency improvement or on software power management in the working states. This research aims to reduce the total standby power amount in the off state. The authors accomplish the goal of reducing the power consumption by a wake-up device which is replaced by a chip with a still lower consumption. The authors redesign the power circuit and cut off the power supply for the unnecessary chips, with the exception of the power needed for the specific chip used to wake up the system. The authors also turn off the power supply of the original power controller chip which is used to control the system's power status. In addition, the authors use another low-power chip instead of the original one and redesign the power sequence of the system in order to maintain the system's power state while the system's power status controller is turned off. Finally, as the authors use this low-power chip to manage the standby power source separately by means of the remote wake-up devices, the authors reduce further the standby power consumption to 4.4 mW in the power-off state by use of the various wake-up methods. The total result is an improvement of approximately 99.3%.

Internet of things (IoT) applications are becoming one of the emerging smart grid enabling technologies. Smart home appliances are one the beneficiary of such applications. Machine-to-Machine and Man-to-Machine are the basic IoT communication platforms that enable home appliances to communicate with each other to be more efficiently operated. In a recent search for the IoT communication protocols that are utilized in smart home appliances, there was no inclusive reference that contains and describes the smart home area networks and guides the research and development (R&D) professionals to select the suitable protocol for an application. This paper presents a comprehensive review of the home area network (HAN) communication protocols that are used to enable bidirectional communication between the home owners, utilities and smart home appliances. The paper presents the most utilized HANs wired and wireless communication protocols and discusses their characteristics, advantages and disadvantages. Index Terms-ZigBee, Wi-Fi, RFID, power line carrier, SPI, I 2 C RS485 I. INTRODUCTION One of the most important and rapidly evolving the technologies in electrical power system is the smart grid. The smart grid is a system of systems that integrates information and communication networks technologies with the traditional electrical power grid. This integration empowers utilities and consumers with bidirectional power flow and communication to better monitor, control and manage electrical power generation, transmission, distribution and consumption. From the communication point of view, the smart grid conceptual model consists of three major communication networks namely; wide area networks, local area networks and consumer area networks. Each one of these networks serves one of the electrical power domains namely; bulk generation and transmission domain, distribution domain and customers' domain respectively. Fig. 1 shows the smart grid communication networks that are mapped with the aforementioned electrical power grid domains [l]-[3]. The wide area network consists of the following sub communication networks:
