IoT based smart fan controller and fire prevention in computer laboratory

A Project Report Submitted in Partial Fulfillment of the Requirements of the Award the Degree of Master of Science in Embedded and Mobile Systems of the Nelson Mandela African Institution of Science and TechnologyComputer laboratory plays the role of key elements with high interest for different categories of populations. Event of fire, smoke, heat and water leakage when occurs could cause a big loss for business continuity. Their equipment is very expensive and its usage is more profitable to the population who used it. Many computer laboratories in the East Africa community region are equipped with equipment for protection against fire, smoke, and heat such as fire extinguishers, fans, and smoke detectors. However, when equipped with that equipment of protection, a system for monitoring and controlling the computer laboratory environment and warning the users in real-time is not yet implemented. This study aimed to develop an automated computer laboratory that would control and monitor the computer laboratory environment from the incident of fire, heat, smoke, and water leakage. The developed system is divided into three nodes which communicate separately with one database in common where the flame sensor is used to detect fire and allow the turning on automatically of a fire extinguisher in case of fire detection, DHT22 and ultrasonic sensor are used for management of fan controller, allowing to turn on automatically fan controller when there is high temperature and if there is a presence of a person, smoke and water sensors are used to detect the presence of smoke and water leakage. NodeMCU ESP8266, ESP32 WROOM-32D as a microcontroller, access point, and software are used to accomplish the development of that system. Different actions of warning users such as triggering buzzers and sending emails are done when fire, smoke, and water leakage are detected, email is sent to the users when there is a temperature more than 25℃. ThingSpeak cloud is used for the analysis of data from sensors, control of fire extinguisher and fan controller were done via mobile application and web applications. A prototyping methodology was used. The study aimed at interviewing 80 individuals based on their cluster. However, 64 individuals accepted to respond to our questionnaires. Results showed that 57.81% of females were interested in the interview compared to 42.19% of males. From the results which come of testing the prototype, it shows that the variation of temperature varies between 23℃ and 27.60℃, 11 times of fire detection, and 33 times of smoke detection. The developed system for IoT-based smart fan controllers and fire prevention in computer labs with its supported equipment will contribute to securing and protecting the computer laboratory against fire, smoldering, heating, and water leakage

Recent advances in IoT, AI, and national technology resilience

Internet of Things (IoT) and Artificial Intelligence (AI) are the critical enablers of the Industrial Revolution 4.0. IoT can be used in many applications that require precision, such as agriculture, industrial automation, education, automotive, and smart cities, to name a few. In other words, IoT is a powerful technology that can solve various business problems. Nevertheless, its integration with AI can help to take automation to the next level. This talk aims to discuss the recent advances in IoT, edge computing, and its applications. First, the IoT and edge commercial adoption survey 2021 will be highlighted. Then, the IoT framework will be introduced to solve a complex problem, including Things, Connect, Collect, Learn, and Do. Especially, the Learn part is very much related to AI. Then, some applications using IoT and edge computing will be presented. Finally, national technology resilience is now a necessity rather than necessary due to the current world situation. Therefore, future directions to enhance national technology resilience will be elaborated

Smart Sensor Technologies for IoT

The recent development in wireless networks and devices has led to novel services that will utilize wireless communication on a new level. Much effort and resources have been dedicated to establishing new communication networks that will support machine-to-machine communication and the Internet of Things (IoT). In these systems, various smart and sensory devices are deployed and connected, enabling large amounts of data to be streamed. Smart services represent new trends in mobile services, i.e., a completely new spectrum of context-aware, personalized, and intelligent services and applications. A variety of existing services utilize information about the position of the user or mobile device. The position of mobile devices is often achieved using the Global Navigation Satellite System (GNSS) chips that are integrated into all modern mobile devices (smartphones). However, GNSS is not always a reliable source of position estimates due to multipath propagation and signal blockage. Moreover, integrating GNSS chips into all devices might have a negative impact on the battery life of future IoT applications. Therefore, alternative solutions to position estimation should be investigated and implemented in IoT applications. This Special Issue, “Smart Sensor Technologies for IoT” aims to report on some of the recent research efforts on this increasingly important topic. The twelve accepted papers in this issue cover various aspects of Smart Sensor Technologies for IoT

"Arte Factus" : estudo e co-design socialmente consciente de artefatos digitais socioenativos

Orientador: Maria Cecília Calani BaranauskasTese (doutorado) - Universidade Estadual de Campinas, Instituto de ComputaçãoResumo: Atualmente, a tecnologia computacional tornou-se cada vez mais pervasiva por meio de computadores de diferentes tamanhos, formas e capacidades. Mas avanços tecnológicos, embora necessários, não são suficientes para tornar a interação com tecnologia computacional mais transparente, como preconizado pela computação ubíqua. Sistemas computacionais atuais ainda exigem um vocabulário técnico de entradas e saídas para serem utilizados. No campo da Interação Humano-Computador (IHC), a adoção da teoria da cognição enativa pode lançar luz sobre um novo paradigma de interação que preenche a lacuna entre ação e percepção. Sistemas computacionais enativos são um promissor tema de pesquisa, mas seu design e avaliação ainda são pouco explorados. Além disso, sistemas enativos, como já proposto na literatura, carecem de consideração do contexto social. O objetivo desta tese de doutorado é contribuir para o design de tecnologia computacional dentro de uma abordagem da cognição enativa, além de também sensível à aspectos sociais. Portanto, esta tese investiga os conceitos de sistemas enativos e socioenativos por meio do co-design de arte interativa e instalações. Para atingir esse objetivo, é proposto um arcabouço teórico-metodológico chamado "Arte Factus" para apoiar o estudo e o co-design socialmente consciente de artefatos digitais. O arcabouço "Arte Factus" foi utilizado em três estudos de design relatados nesta tese: InterArt, InstInt e InsTime. Esses estudos envolveram a participação de 105 estudantes de graduação e pós-graduação em Ciência da Computação e Engenharia de Computação no co-design de 19 instalações. O processo envolveu o uso de tecnologia pervasiva do tipo Faça-Você-Mesmo ("Do-It-Yourself, DIY"), e algumas dessas instalações foram estudadas em oficinas de prática situada que ocorreram em cenários educacionais (escola e museu exploratório de ciências). O arcabouço "Arte Factus", como a principal contribuição desta tese de doutorado, mostrou-se eficaz no apoio ao co-design socialmente consciente de instalações interativas que materializam o conceito de artefatos digitais socioenativos. Além disso, através do estudo dos artefatos criados no contexto desta investigação, esta tese também contribui para a construção teórica do conceito de sistemas socioenativosAbstract: Currently, computational technology has become more and more pervasive with computers of different sizes, shapes, and capacities. But technological advancements, although necessary, are not enough to make the interaction with computational technology more transparent, as preconized by the ubiquitous computing. Current computational systems still require a technical vocabulary of inputs and outputs to be interacted with. Within the field of Human-Computer Interaction (HCI), the adoption of the enactive cognition theory can shed light on a new interaction paradigm that bridges the gap between action and perception. Enactive computational systems are a promising subject of research, but their design and evaluation are still hardly explored. Furthermore, enactive systems as already proposed in the literature lack a social context consideration. The objective of this doctoral thesis is to contribute towards the design of computational technology within an enactive approach to cognition, while also being sensitive to social aspects. Therefore, this thesis investigates the concepts of enactive and socioenactive systems by enabling the co-design of interactive art installations. To achieve this objective, a theoretical-methodological framework named "Arte Factus" is proposed to support the study and socially aware co-design of digital artifacts. The "Arte Factus" framework was used in three design studies reported in this thesis: InterArt, InstInt, and InsTime. These studies involved the participation of 105 Computer Science and Computer Engineering undergraduate and graduate students in the co-design of 19 installations. The process involved the use of pervasive "Do-It-Yourself" (DIY) technology, and some of these installations were further studied in workshops of situated practice that took place in educational scenarios (school and exploratory science museum). The "Arte Factus" framework, as the main contribution of this doctoral thesis, has shown effective in supporting the socially aware co-design of interactive installations that materialize the concept of socioenactive digital artifacts. Moreover, through the study of the artifacts created in the context of this investigation, this thesis also contributes towards the theoretical construction of the concept of socioenactive systemsDoutoradoCiência da ComputaçãoDoutor em Ciência da Computação2017/06762-0FAPESPCAPE

A taxonomy of cyber-physical threats and impact in the smart home

In the past, home automation was a small market for technology enthusiasts. Interconnectivity between devices was down to the owner’s technical skills and creativity, while security was non-existent or primitive, because cyber threats were also largely non-existent or primitive. This is not the case any more. The adoption of Internet of Things technologies, cloud computing, artificial intelligence and an increasingly wide range of sensing and actuation capabilities has led to smart homes that are more practical, but also genuinely attractive targets for cyber attacks. Here, we classify applicable cyber threats according to a novel taxonomy, focusing not only on the attack vectors that can be used, but also the potential impact on the systems and ultimately on the occupants and their domestic life. Utilising the taxonomy, we classify twenty five different smart home attacks, providing further examples of legitimate, yet vulnerable smart home configurations which can lead to second-order attack vectors. We then review existing smart home defence mechanisms and discuss open research problems

A Network of One’s Own: Struggles to Domesticate the Internet

This thesis is a design research practice-led inquiry into the domesticated Internet. It first seeks to complicate simplistic corporate and academic visions by naming some of the struggles it encounters – not least to assert a private home and network of one's own. It is argued that a century of domestic technologies has emphasised invisibility, ubiquity, and automation in ways that obscure a network of exploited people and finite resources. Furthermore, these technological ambitions are met through machine surveillance, in ways newly enabled by the domesticated Internet, that threaten the privacy of the home. In response, this thesis seeks some practical ways to design alternatives that assert a network of one's own and makes the work it implicates visible. The methodological approach is broadly Research Through Design supplemented by a practice described as designerly hacking through which hidden technical potential is revealed and given meaning. Two empirical studies are described that together make an account of the technical possibility and social reality of the networked home: an autobiographical technical exploration of the author's home and network with the making of hacks and Research Products privately and in public; and a cultural probe engagement with six rented households surfacing contemporary accounts of the domesticated Internet and in particular the challenges and opportunities of wireless networking. Together this yields a series of technical and social insights for design and two forms are offered to communicate these: a framework for understanding change in the networked home (The Stuff of Home) and a set of 30 design patterns for a network of one's own; each invites different analyses. The conclusion then draws together the multiple threads developed through this thesis and offers some reflection on the complexity of doing contemporary technical design work

Shortest Route at Dynamic Location with Node Combination-Dijkstra Algorithm

Abstract— Online transportation has become a basic requirement of the general public in support of all activities to go to work, school or vacation to the sights. Public transportation services compete to provide the best service so that consumers feel comfortable using the services offered, so that all activities are noticed, one of them is the search for the shortest route in picking the buyer or delivering to the destination. Node Combination method can minimize memory usage and this methode is more optimal when compared to A* and Ant Colony in the shortest route search like Dijkstra algorithm, but can’t store the history node that has been passed. Therefore, using node combination algorithm is very good in searching the shortest distance is not the shortest route. This paper is structured to modify the node combination algorithm to solve the problem of finding the shortest route at the dynamic location obtained from the transport fleet by displaying the nodes that have the shortest distance and will be implemented in the geographic information system in the form of map to facilitate the use of the system. Keywords— Shortest Path, Algorithm Dijkstra, Node Combination, Dynamic Location (key words
