A Non-intrusive IoT-Based Real-Time Alert System for Elderly People Monitoring

Typically, elderly people may be living alone for part of the day or full time, and may have difficulties or problems with mobility, but they want to maintain their independence and autonomy. Internet of Things (IoT) technology may be used to contribute to increasing the degree of security of these people in their own homes, in a much more discreet and non-intrusive way than the typical commercially available systems, providing real-time data about the status of these people to their family members or caretakers. In this article, a non-intrusive IoT-based real-time alert system to be used by elderly people is proposed, using simple and low-cost “of the shelf” electronic components. It is also intended that this solution can integrate other monitoring devices already available on the market, such as bracelets, video cameras, robots, among others. Both laboratorial and house-hold tests have been conducted to prove the effectiveness of the system.
