Activity Monitoring and Alert System for Elderly People in Smart Homes

The rapid ageing of the population poses difficulties for elderly people who live alone. It gets more difficult for people who live in rural areas. As a result, there is an immediate need for real-time monitoring via the internet of things (IoT). In this work, An activity monitoring and alert system are proposed, which monitors health parameters such as ECG, oxygen amount in the blood, fall detection, and the person’s activity. The individual monitors his or her heart disease using various wearables. The chest strap is used to read the ECG signal, the wrist strap is used to check the oxygen level in the blood, and the footwear is used to detect falls. To reduce false alarms, three modules are integrated. For activity monitoring, multiple sensor nodes are placed throughout the house. Any deviation from the parameters sends a message to the cloud database, alerting family members, doctors, and emergency services. The proposed system is useful for providing medication and assistance on time.
