Abstract
The Smart Bracelet for Elderly People is an innovative solution that aims to detect and locate people especially for elderly people with a health problem. It is designed as a remote alert system for people at risk of stroke, sudden heart attack, and seizures. The smart bracelet provides fall detection system, GPS tracker to trace the current location and a medicine reminder setting to remind pill intake on time. This device is synchronized with the FAVORIOT platform which stores GPS data and fall detection indicator.
Introduction
The Smart Bracelet for Elderly People is an innovative solution that aims to detect and locate people especially for elderly people with a health problem. It is designed as a remote alert system for people at risk of stroke, sudden heart attack, and seizures. The smart bracelet provides fall detection system, GPS tracker to trace the current location and a medicine reminder setting to remind pill intake on time. This device is synchronized with the FAVORIOT platform which stores GPS data and fall detection indicator.
The bracelet can be used for elderly people staying alone when the child lives elsewhere. The child can monitor the condition of their parent which will avoid worrying feeling at all times. If a bracelet detects any fall that threatens their parent life, the device will automatically send an email or alert message to the child then if the parents do not answer the phone, we’ll know something might happen to them.
Other than this, the smart bracelet has a tracking system that has access to GPS technology. This means that the parent can spend their time outside of their home to do shopping, sport and other. In the case of a parent may be lost and fall outside of their
home, the bracelet can provide accurate location of their parent. Another functionality of the smart bracelet act as medicine reminder to remind elderly people to take their pills; if it is neglected, this service warns the prescribed care provider. It provides an easy-to-use dispenser that helps maintain the appropriate medication schedule. Elderly patients hear audio reminders when it’s time to take their pills.
Design and Implementation
The smart bracelet is designed based on Arduino UNO which is selected as the microcontroller. The Arduino is connected to accelerometer sensor for fall detection. GPS module for location tracking and a real time clock module for medicine reminder. The buzzer is connected to alarm sound when it is time to take the medicine. The block diagram of the systems is as shown in Figure 2.1 below.

Conclusion
The smart bracelet is able to send an alert message to the children if their parent fall and they can take immediate and necessary action. The medicine reminder reminds the elderly people to consume prescribed medicine. The GPS tracker only and can locate the current location of the elderly people. As human life longer nowadays, we believe that this device becomes important device near the future.
