This study focuses on MedEasyNa, a SMART medicine dispenser that is designed to
enhance medication adherence targeted among individuals with chronic illnesses and
comorbidities. MedEasyNa features an ESP32 microcontroller at its center, enabling IoT-based
Notifications, real-time monitoring, and GPS tracking using the companion app. Through
controlled tests and several weeks of user trials, MedEasyNa was able to meet its five core
objectives. The Health Monitoring System presented minor deviations from traditional devices
(±0.1–0.3°C for temperature, ±1–4 bpm for heart rate, ±1–3% for oxygen saturation) although
with slower response times (7–20s). Its accuracy was rated at 79.8% by the users, and at 74.4%
by caretakers. For the Medicine Dispensing System, it achieved 100% accuracy in testing, with
users rating it 80%, and caregivers giving it 77.2%, even though there were occasional jams
encountered. The Android app was rated 83.1% by users, and showed effective alerts and
monitoring, despite occasional crashes. On the other hand, Firebase-to-ESP32 interface enabled
reliable data sync in real time, earning high ratings from users 84.2%. Overall, the system was
rated 74.2% among users and 79.8% among caregivers. Although network instability affected
consistency, MedEasyNa effectively delivered its core functions, offering a promising innovation
to improve healthcare management.
