Group representative Ngo Vu Kha v PROJECT SUMMARY DESIGN ELDERLY HEALTHCARE SYSTEM In today's world, with the continuous advancement of technology, the trend of applying science and technology to daily life is increasing. Therefore, the team has chosen a practical topic that is relevant to everyday life and simultaneously addresses a common concern for families with elderly members.
One of the major challenges for the elderly is health-related issues. Age-related conditions such as heart disease, diabetes, and high blood pressure are becoming more prevalent. Managing and monitoring health becomes a top priority. The life of the elderly is not without challenges.
However, with the current technological development, there are many health monitoring devices available to assist in caregiving. The team has chosen this topic for the graduation thesis with the hope of providing a useful and practical method that can be applied in real life, offering convenience in the care and monitoring of the health status of the elderly. The designed system will include the following functionalities: GPS location tracking for the elderly when wearing the device, sending notifications to the phone and messages with the location in case of falls and getting lost. Monitoring health indicators such as heart rate and blood oxygen levels.
Additionally, the system can generate reminders for scheduled events such as exercise sessions, medication reminders, and follow-up appointments. Throughout the project, the team will delve into programming ESP, Android development, and IOT systems that can meet the needs of daily life. vi LIST OF CONTENT GRATITUDE. vi LIST OF CONTENT.

With the powerful development of technology today, smart healthcare devices are no longer unfamiliar to humans.
They can continuously collect and analyze health data, allowing individuals to monitor changes in health indicators and receive alerts about potential issues before they become more serious. This helps enhance the early detection and prevention of diseases. In addition, for the elderly who often need to use medication for prevention and treatment of various diseases, monitoring the medication cycle is also crucial. With smart devices, they can help the elderly monitor and remember to take medication at the right time and dosage, avoiding the risk of forgetting or misuse of medication, as well as keeping track of regular medical check-ups.
Smart devices have the ability to send automatic alerts in case of emergencies, such as falls, slip risks, or unusual health conditions. This is particularly important for the elderly, whose memory may decline, leading to situations where they may get lost and not remember the way back home. This capability can be a lifesaver in dangerous situations.2 Scientific and Practical Significance of the Research Topic 1.1 Scientific This research demands an approach to programming and electronics. The integration of these fields helps drive innovation and technological development in the design and establishment of health monitoring systems, catering to the specific needs of the elderly.
Understanding the requirements, realities, and limitations of the elderly in monitoring their health status necessitates in-depth analysis of design thinking, weight computation, size, and safety to ensure convenience and safety for users.2 Practical Significance The research project provides practical value by addressing the needs of monitoring the health status of the elderly. The monitoring device alleviates difficulties and barriers for families with elderly members.
