Solar tracking systems enable increased efficiency of a photovoltaic system through a continuous adjustment of its position with respect to the sun, thus increasing the generation of electrical energy. The integration of photovoltaic solar tracking systems in buildings and houses enables the energy needs of users in a broader way to be covered. This integration is facilitated through the existence of technologies such as access to the Internet through Wi-Fi, which allows developing systems to be encompassed within the domain of the “Internet of Things” (IoT). In this study, a first-of-its-kind “open-loop” solar tracker was designed and developed, which executes the tracking algorithm in the Firebase web service and allows the exchange of data with said service through a NodeMCU development board, which has an integrated Wi-Fi module. After an experimental campaign in Aguascalientes, central Mexico, gains in terms of collected energy on average were measured at 29.9% in May compared to an optimally tilted fixed photovoltaic system. This study opens the possibility of integrating power generation systems into the IoT domain, which, among other things, allows for constant monitoring of the behavior of the system.

Solar tracking systems allow greater efficiency of a photovoltaic system by continuously adjusting its position in relation to the sun, thus increasing the generation of electrical energy. The integration of photovoltaic solar tracking systems in a photovoltaic plant allows the energy needs of users to be met more widely in a smaller area. This integration is facilitated by the existence of technologies such as access to the Internet via Wi-Fi, which allows the development of systems to be included in the domain of “Cloud” and Automation 4.0. In this study, an "open circuit" solar tracker, the first of its kind designed in Brazil on a plant scale, was designed and developed, which runs the tracking algorithm in the service programmed in a PLC, which has a Wi-Fi module integrated. This study opens the possibility of integrating power generation systems in the Cloud domain, which among other things, allows constant monitoring of the system's behavior with Solar tracking

Solar Tracker

Main challenge of solar-tracking systems are the sunlight detection, providing position and delay of PV movement, designing control module for low consumption dc servo motor(s). Objective of this paper is designing and implementing automatic control for detecting maximum solar light to a solar panel. The two-axis solar tracker is used for optimizing conversion of solar energy into electrical energy, at cost of the mechanical and the maintenance need, for the best efficiency. The hardware development, two dc servomotors are adjusted which is controlled by drive module moving panel by using four Light-Dependent Resistor (LDR) to provide the analog signals; the signals are processed by ATMEGA328P micro-controller with Arduino.

Undeniably, the Internet of Things (IoT) ecosystem continues to evolve at a breakneck pace, exceeding all growth expectations and ubiquity barriers. From sensor to cloud, this giant network keeps breaking technological bounds in several domains, and wireless sensor nodes (motes) are expected to be predominant as the number of IoT devices grows towards the trillions. However, their future in the IoT ecosystem still seems foggy, where several challenges, such as (i) device’s connectivity, (ii) intelligence at the edge, (iii) security and privacy concerns, and (iv) growing energy needs, keep pulling in opposite directions. This prospective paper offers a succinct and forward-looking review of recent trends, challenges, and state-of-the-art solutions of low-end IoT motes, where reconfigurable computing technology plays a key role in tomorrow’s IoT devices.

A lot of period, due to negligence of hospital staff, or insensitivity of relatives it may happen that medication is not observed correctly, and it may go ahead to cause heart attack or other life-threatening situations. Thus, this research study presents proposed systems which include arrangement of sensor tools and Internet of Things (IoT). Using this structure one can manage electrical energy equipment’s and monitor level of the medicine from a distant place and keep an eye on entire development. In this structure using IoT, one can normalize electrical appliances and constantly supervised patients from remote location. The internet of things technology is a innovative change maker for the health care engineering. It is changing healthcare field by dropping functioning costs and serving caretakers centre of attention on treating patients in a better mode. This method consists of a number of sensors. Controlling and data processing is done through the ESP8266, all the sensors are connected to Arduino Uno. Through this system, we can measure Temperature, heartbeat, and BP. Through sensors, it is possible to measure all these values. These values are then used for detecting any situation. In case of a critical situation, an alert can be given as a telegram message it is possible to monitor the person’s health from any location in the world through the mosquito server cloud. The project uses a MQTT protocol for monitoring patients. Condition through the mobile Application. The data from sensors is uploaded to the cloud server, periodically without any interruption if the internet is available. Through this system one can efficiently monitor patient’s condition.

<p class="0abstract">Since the emergence of the Coronavirus and its declaration as a global pandemic, the world has changed all sectors radically. Covid-19 has caused a very strong effect on daily life and adaptation to new ways of learning, working, and communicating. The smart city is one of the most important solutions that enable us to go on with daily life during the pandemic and beyond. The smart city employs the current technology and smart solutions to serve the community, and improve the services provided to the people, particularly in vital sectors such as health, education, electricity, transportation, communications, and others. This article deals with two innovative applications for the Internet of things in smart cities: The first refers to designing an intelligent health monitoring system, which aims to reduce the spread of Coronavirus infection from people to the medical staff, as well as reduce work pressure on the medical staff. The second application refers to monitoring electrical energy consumed by measuring and monitoring electrical parameters and energy consumption. In addition, it helps us to know the power line trespasser. Both systems are implemented by using sensors to gather data in real-time and then transmit it to the server.</p>

The existing stand-alone multimedia machines and online multimedia machines in the market have certain deficiencies, so they cannot meet the actual needs. Based on this, this research combines the actual needs to design and implement a multi-media system based on the Internet of Things and cloud service platform. Moreover, through in-depth research on the MQTT protocol, this study proposes a message encryption verification scheme for the MQTT protocol, which can solve the problem of low message security in the Internet of Things communication to a certain extent. In addition, through research on the fusion technology of the Internet of Things and artificial intelligence, this research designs scheme to provide a LightGBM intelligent prediction module interface, MQTT message middleware, device management system, intelligent prediction and push interface for the cloud platform. Finally, this research completes the design and implementation of the cloud platform and tests the function and performance of the built multimedia system database. The research results show that the multimedia database constructed in this paper has good performance.
