This system is a smart home automation solution designed to support elderly individuals in managing their daily household tasks with ease and minimal physical effort. It provides a cost-effective, reliable, and user-friendly solution that integrates Bluetooth communication, Arduino microcontrollers, and smart sensors to control appliances such as lights, fans, and doors. Existing initiatives in elderly care technologies, including IoT-based smart homes, wearable sensors for health monitoring, and Bluetooth-enabled automation systems, have demonstrated the potential of technology in improving independence and safety for older people. However, these systems frequently face challenges such as high implementation costs, complex user interfaces, limited scalability, and network dependence. This system overcomes those challenges by providing a simplified mobile application with efficient Bluetooth-based communication and additional features such as rain detection and an automatic cloth collector, enhancing both indoor convenience and outdoor safety. The system is built on a five-layer architecture: a user layer that provides a simple mobile app interface, an application layer that processes commands, a communication layer that transfers data through Bluetooth, a control layer where the Arduino Uno executes logic and sensor operations, and a device layer consisting of appliances and sensors. This layered approach ensures seamless interaction between users, processing, and devices, enabling both manual and automated control in real time. The implemented algorithms include a Bluetooth communication algorithm for pairing and command transfer, a device control algorithm utilizing IF-ELSE logic, a servo motor algorithm employing pulse-width modulation (PWM), and a rain detection algorithm with threshold-based sensor readings. The results of this work demonstrate that this system successfully enables elderly individuals to perform household tasks with minimal effort, increases accessibility through a straightforward mobile app, and shows potential for scalability as an affordable assistive technology solution.
This paper presents an IoT-based autonomous robot car system leveraging ESP8266 and ESP32 microcontrollers to provide a smart, versatile, and cost-effective solution for surveillance, remote patient monitoring, and facility management in hospitals. Equipped with biomedical sensors (heart rate, body temperature), environmental sensors (gas, temperature, humidity), and an ESP32-CAM for live video streaming, the system enables continuous, contactless monitoring of patients and hospital environments. Data is securely transmitted to a centralized cloud platform, allowing healthcare professionals to track patient status and receive real-time alerts for any anomalies. The ESP8266 acts as the main communication module, facilitating wireless connectivity and data exchange between the robot car and a central monitoring station. The system is controlled through a user-friendly web interface and the Blynk mobile app, enabling remote navigation and management through smartphones or laptops. Smart navigation and obstacle avoidance algorithms allow the robot car to autonomously patrol hospital zones, supporting facility surveillance, route inspection, and hazard detection. By integrating IoT technologies with autonomous robotics, this system enhances patient safety, reduces healthcare workers' exposure to infectious environments, and streamlines hospital operations, proving especially valuable during pandemics. Its design prioritizes ease of use, adaptability, and real-time remote monitoring, making it an efficient tool for modern healthcare management.
One of the most important sources of life is water. It is common knowledge that water is the source of life and that clean water is essential for life to exist on Earth. The majority of these pollutants are poisonous and harm all dependent organisms as well as water resources such as lakes, rivers, and seas. The marine ecology is impacted by these plastic wastes. Therefore, it is essential to clean up the trash in the ocean and eliminate water pollution. The majority of the time, cleaning the water bodies by hand with human labor takes a lot of time and money. To address this, the prototype for a surface waste collection system in water bodies is one such system, which has a systematic method to remove the waste debris from water bodies with comparatively less human interference. The architecture of this machine consists of a cleaner mechanism for collecting and removing waste from water bodies using a belt-driver mechanism. The conveyor belt that is powered by a battery continuously rotates in a backward direction by taking water debris into the collector bin. A solar panel is used to charge the battery, which is a great way to use renewable energy. The boat moves in the direction given by the operator through a wireless device.
The development of smart ventilator systems represents a significant advancement in medical technology, particularly in the field of critical care. These intelligent ventilators integrate cutting-edge technologies, data analytics, and artificial intelligence to enhance patient outcomes, optimize ventilation strategies, and improve overall patient care. This paper provides a comprehensive review of the current state of smart ventilator systems, including their components, functionalities, benefits, challenges, and future prospects. The discussion also covers the potential impact of these systems on healthcare and the advancements needed to unlock their full potential. The primary issue that a COVID-19- infected patient typically dealt with was the respiratory issue. It is to be hoped that the recent introduction of small-scale technologies such as microcontroller, ventilator, and Continuous Positive Airway Pressure (CPAP) will largely be employed to address the issue linked with medical equipments for breathing.
The rapid evolution of digital electronics has transformed how embedded systems interface with personal computers and industrial equipment. Among various communication protocols, the Universal Serial Bus (USB) stands out for its versatility, speed, and plug-and-play functionality. However, in applications where electrical noise, ground potential variations, or high voltages exist, such as industrial automation or medical instrumentation, direct USB connections can compromise safety and signal integrity. This paper presents the design and evaluation of a galvanically isolated USB interface that provides reliable communication between embedded devices and host systems while maintaining electrical isolation. The proposed design integrates a data isolation stage using ISOUSB111 and an isolated DC–DC converter for power separation. Together, these ensure complete protection against transient voltages, electrostatic discharge (ESD), and ground loops. Complying with IEC 60601-1 medical safety standards, the design achieves robust isolation suitable for medical and industrial environments. Experimental validation demonstrates stable USB 2.0 full- speed data transfer (12 Mbps) and reinforced insulation capable of withstanding 5 kV AC potential difference.
