Design and implementation of microcontroller based short message service control system

BackgroundTuberculosis (TB) is global health concern and a leading infectious cause of mortality. Reversing TB incidence and disease-related mortality is a major global health priority. Infectious disease mortality is directly linked to failure to adhere to treatments. Using technology to send reminders by short message services have been shown to improve treatment adherence. However, few studies have examined tuberculosis patient perceptions and attitudes towards using SMS technology to increase treatment adherence. In this study, we sought to investigate perceptions related to feasibility and acceptability of using text messaging to improve treatment adherence among adults who were receiving treatment for TB in Callao, Peru.MethodsWe conducted focus group qualitative interviews with current TB positive and non-contagious participants to understand the attitudes, perceptions, and feasibility of using short message service (SMS) reminders to improve TB treatment adherence. Subjects receiving care through the National TB Program were recruited through public health centers in Ventanilla, Callao, Peru. In four focus groups, we interviewed 16 patients. All interviews were recorded and transcribed verbatim. Thematic network analysis and codebook techniques were used to analyze data.ResultsThree major themes emerged from the data: limits on health literacy and information posed challenges to successful TB treatment adherence, treatment motivation at times facilitated adherence to TB treatment, and acceptability of SMS including positive perceptions of SMS to improve TB treatment adherence. The majority of patients shared considerations about how to effectively and confidentially administer an SMS intervention with TB positive participants.ConclusionThe overall perceptions of the use of SMS were positive and indicated that SMS technology may be an efficient way to transmit motivational texts on treatment, health education information, and simple reminders to increase treatment adherence for low-income TB patients living in Peru.

The proliferation of Internet of Things (IoT) technology has transformed the way we interact with home appliances. This study investigates the technical feasibility and energy efficiency of Wi-Fi-based IoT remote monitoring and control of home appliances. A prototype system was designed and developed using Wi-Fi-enabled microcontrollers, sensors, and actuators to monitor and control various appliances remotely through a mobile application.

The system's technical feasibility was evaluated through reliability, scalability, and security assessments. Results indicate high reliability (99.85%), scalability (supporting up to 50 devices), and robust security. Energy efficiency was analyzed using Energy Consumption Analysis (ECA) methods. The study concludes that Wi-Fi-based IoT remote monitoring and control of home appliances is technically feasible and energy-efficient, offering significant potential for reducing energy consumption and carbon emissions.

As a smart consumer, there is always a need for us to identify the quality of the goods we want to buy, such as trying to choose the better mango amongst the others in a fruit market. With the popularity of the mobile phone and the maturity in wireless messaging technology, it is no more a dream for us to get the information we want anywhere, anytime. This paper proposes a new mobile data service that includes signal processing service via MMS (Multimedia Messaging Service) and SMS (Short Messaging Service). This paper discusses the study, design, construction and analysis of a fully automated consumer-based prototype wireless system which interconnects signal processing tools with consumers using MMS and SMS technology. The system with signal processing application processes the information sent by the consumer using MMS. Then it sends back the grading result to the consumer using SMS.

Recent advances in multimedia network systems and mechatronics have led to the development of a new generation of applications that associate the use of various multimedia objects with the behavior of multiple robotic actors. The connection of audio and video devices through high speed multimedia networks is expected to make the system more convenient to use. For example, many home appliances, such as a video camera, a display monitor, a video recorder, an audio system and so on, are being equipped with a communication interface in the near future. Recently some platforms (i.e. UPnP 1 , HAVi 2 and so on) are proposed for constructing home networks; however, there are some issues to be solved to realize various services by connecting different equipment via the pervasive peer-to-peer network. UPnP offers network connectivity of PCs of intelligent home appliances, practically, which means to require a PC in the network to control other devices. Meanwhile, HAVi has been developed for intelligent AV equipments with sophisticated functions using high CPU power and large memory. Considering the targets of home alliances are embedded systems, this situation raises issues of software and hardware complexity, cost, power consumption and so on. In this study, we have proposed and developed the service oriented network architecture for control and management of home appliances, named SONICA (Service Oriented Network Interoperability for Component Adaptation), to address these issues described before.

This paper presents the development of GSM-based control home appliances for smart home system. The main aim of the prototype development is to reduce electricity wastage. GSM module was used for receiving short message service (SMS) from user?셲 mobile phone that automatically enable the controller to take any further action such as to switch ON and OFF the home appliances such as light, air-conditioner etc. The system was integrated with microcontroller and GSM network interface using assembly language. MPLAB software was utilized to accomplish the integration. The system is activated when user sends the SMS to controller at home. Upon receiving the SMS command, the microcontroller unit then automatically controls the electrical home appliances by switching ON or OFF the device according to the user order. In other word, it read message from the mobile phone and response to control the devices according to the received message. The prototype has been successfully developed and it could provide an effective mechanism in utilizing the energy source efficiently.

This article discusses face and hand sign recognition and its applications. We have already proposed a method that can recognize faces and hand signs using hierarchical discriminant analysis. Here, we implement this method on a laptop computer and develop a real-time system that can control home appliances by recognizing faces and hand signs. Our system can control various appliances in the home by remote control. Moreover, since our system can recognize the user, it can assign distinct commands to the hand signs of each user and limit the appliances and functions that users can control.

Real-time Energy Monitoring and Controlling System based on ZigBee Sensor Networks

With the development of intelligent home appliance technology, real-time home appliance status information is now generated in large quantities. New technology is necessary in order to process the large amount of status information that is generated every day. An innovative technology that has recently been used to process large amounts of data is cloud computing. Therefore, in this paper, we propose a system model to control and monitor home appliances using home network and cloud computing technologies in a smart home environment. UPnP technology is used to extract status information from home appliances. Cloud computing technology analyzes and processes the information and also provides virtualization services to users. In the proposed method, the gateway collects and stores home appliance information using home network technologies and sends the information to the cloud server for storage and management.

Mobile technologies are growing rapidly in all countries, but they are particularly important for developing countries. Since more and more citizens are using cell phones and other mobile devices, it seems clear that there is an opportunity for government agencies to provide information and services using these technologies. Despite the relative success of some growing applications and the great number of mobile phones, mobile government has not evolved as one of the main channels for interacting with citizens. Aiming to understand the configuration of mobile government projects in practice, our research question is: how environment, structure, leadership, strategy and sustainability configure and interact in mobile government business models? The research has a qualitative character with multiple cases studies based on the analysis of twenty Mobile Government Projects using short message service (SMS) in the government of Paraná, Brazil. The life cycles of the twenty cases were identified and represented, from the birth to the survival phase. The major contribution of this paper is proposing a Dynamic Business Model for Mobile Government using SMS technology, based on the phases of the project life cycle.

With the rapid development of economy, science, and technology, people have higher and higher requirements for the quality of home life, and smart home systems are required to have higher convenience and comfort. The continuous development of embedded technology, short‐range wireless communication technology, and microcontroller technology provides a new development direction for the research and development of smart home systems. Under the premise of fully studying the research status and development trend of smart home systems, this paper combines embedded technology, ZigBee wireless communication technology, voice recognition technology, GSM communication technology, etc., and proposes a ZigBee‐based smart voice home appliance control system. The system adopts ZigBee wireless communication to form a comprehensive management system for household electrical appliances, electronic and electrical equipment, etc., for household electrical control, intelligent security, and environmental monitoring. This paper designs the overall scheme of a smart home control system based on voice recognition technology. According to this scheme, the hardware and software of the system are designed, and the wireless communication method combining Wi‐Fi and RF (radio frequency) of the system is also determined. In order to make the system more humane, two sets of control schemes, voice control and button control, are designed according to the system’s functional requirements. In the voice control solution, the user first reads the control commands set in the voice library on the smart terminal, and then, the system automatically recognizes the commands read by the user. After the recognition is successful, the user can control the home appliances through the command. In the key control scheme, users can control home appliances through keys on the smart terminal. The upper computer transplants the audio library and the algorithm studied in this paper to realize the audio collection and storage, the confirmation of family members, and the recognition of voice commands; the lower computer is used for real‐time collection of environmental information and wireless control of home facilities. After the system is started, the family members are first confirmed by voice, and then, the voice command recognition result and real‐time environmental information jointly decide to form a control command. The upper computer sends the control command to the lower computer through the serial port to control the corresponding home equipment. The system is tested and analyzed under experimental conditions. The test results show that the system can control home facilities through voice commands combined with real‐time environmental information while confirming family members.

Home Network System(HNS), which connects home appliances and sensors to networks, has been researched actively. HNS makes it possible to remote-control and monitor home appliances. However, use of these services has been limited to home appliances and sensors in HNS.In this paper, we present integrated services combining RSS documents and HNS with our RSS conversion service. In our service, the hyperlink in each item on an RSS document is replaced to a WebAPI of home appliance control. This converted RSS(integrated RSS) can control home appliances by clicking items in an RSS reader.

Performing motor activities including activities of daily living (ADL) on their own is challenging for individuals who have lost their motor functionalities due to various conditions such as spinal cord injuries, cerebral palsy, spinal muscle atrophy etc. Their mobility is also restricted depending on the severity of the disability. This paper proposes an Electroencephalography (EEG) signals based brain machine interface (BMI) for a wheelchair along with the facility to control various home appliances depending on the location of the user. The proposed BMI uses Steady State Visual Evoked Potentials (SSVEP) of EEG signals to identify the user intentions and recognized intentions are used to control the wheelchair (by wheelchair controller) or operate different home appliance connected to the system (by home appliance controller) based on the location information estimated by a Bluetooth localization beacon system. A set of experiments were carried out with healthy subjects to validate the proposed system and the results yielded that the proposed BMI system has the ability to effectively control the wheelchair as well as different home appliances connected to system using only less number of user intention signals.

This paper describes the design of an innovative and low cost self-assistive technology that is used to facilitate the control of a wheelchair and home appliances by using advanced voice commands of the disabled people. This proposed system will provide an alternative to the physically challenged people with quadriplegics who is permanently unable to move their limbs (but who is able to speak and hear) and elderly people in controlling the motion of the wheelchair and home appliances using their voices to lead an independent, confident and enjoyable life. The performance of this microcontroller based and voice integrated design is evaluated in terms of accuracy and velocity in various environments. The results show that it could be part of an assistive technology for the disabled persons without any third person’s assistance.

Integrating Internet of Things (IoT) technology in home control systems has led to a significant advancement in the control and monitoring of home appliances and environmental conditions. This study presents the development of an IoT-based home control system that uses the NodeMCU ESP8266 microcontroller to manage several home appliances. This system connects to a Firebase real-time database to store or retrieve data in real-time. The user interacts with the IoT system through a mobile application named My Home, developed using Java programming language, and this mobile application is also interfaced with the Firebase cloud server. The developed IoT system allows users to control home appliances such as lights, sockets, fans, and cookers, and it also provides real-time updates of environmental parameters, such as temperature and humidity, which are measured by a DHT11 sensor. In addition, a PIR motion sensor was integrated into the system to enhance the home's security by detecting intrusion. The system's hardware functionality is based on a written Arduino code, which establishes Wi-Fi connectivity to a predefined network, communicates with the Firebase database, handles appliance control and manages sensor data. This IoT-based home control system shows the potential of integrating microcontrollers with cloud services to create a smart, responsive and user-friendly home control platform. The developed IoT system offers a foundation for advancements, thereby making it a valuable contribution to the growing field of smart home technology.

The project proposes an efficient implementation for IoT (Internet of Things) used for monitoring and controlling the home appliances via World Wide Web. Home automation system uses the portable devices as a user interface. They can communicate with home automation network through an Internet gateway, by means of low power communication protocols like Zigbee, Wi-Fi etc. This project aims at controlling home appliances via Smartphone using Wi-Fi as communication protocol and raspberry pi as server system. The user here will move directly with the system through a web-based interface over the web, whereas home appliances like lights, fan and door lock are remotely controlled through easy website. An extra feature that enhances the facet of protection from fireplace accidents is its capability of sleuthing the smoke in order that within the event of any fireplace, associates an alerting message and an image is sent to Smartphone. The server will be interfaced with relay hardware circuits that control the appliances running at home. The communication with server allows the user to select the appropriate device. The communication with server permits the user to pick out the acceptable device. The server communicates with the corresponding relays. If the web affiliation is down or the server isn't up, the embedded system board still will manage and operate the appliances domestically. By this we provide a climbable and price effective Home Automation system.
