Wearable Device Equipped with Door Alert and Mobile App for Security and Supervision

Nowadays the percentage of old aged people that have Alzheimer's disease has increased over the years. Alzheimer's disease is one of the most crucial diseases that our loved ones might acquire. In this study, a device for patients with Alzheimer's disease and a mobile application for the guardian/s to lessen their stress and worries when taking care of the patient were developed. It is called Patient Security & Supervision Equipment(PS & SE), which has a 3-layer security, mainly: [1] The door alert that is equipped with modules like UHF RFID reader which is used as an identifier for the patient, and an activator for the PIR sensor, a motion detector and, a Wi-Fi module for the connection of the door alert to send notifications to the mobile application; [2] The wearable device that is equipped with modules, such as a GPS tracker to know the location of the patient, a GSM module used by the GPS module in sending coordinates to the Firebase database, and a UHF RFID tag. [3] Lastly, the mobile application, named as PSSE, is used by the guardian/s to check the location of the patient. Passcode security is required before accessing the application. Based on a series of testing, the device's accuracy and efficiency for locating the patient depend on the signal/speed of the internet on a certain location. Hence, the system is said to be viable and feasible in the medial industry for its application of Alzheimer's patients and the other mentally challenged patients after the evaluation and validation of a specialist doctor.
