LIFY: IoT System for Monitoring Vital Signs of Elderly People

This article describes the implementation of a technological solution aimed at improving the recording of physiological signals in the elderly population residing in geriatric facilities. The developed system consists of a smart device equipped with sensors for body temperature, heart rate, and blood oxygen levels. This device establishes an Internet connection to transmit data to a cloud-based platform for storage. Within this platform, a dashboard has been created to visualize real-time values captured by the sensors, along with additional functionalities such as user management and the configuration of personalized alerts, which are transmitted to the solution's users through the instant messaging system called Telegram.
