Abstract: Medication non-adherence among elderly patients is a common healthcare problem that can lead to serious health risks and increased medical costs. Traditional pillboxes and reminder systems do not verify whether medicines are actually taken and fail to monitor storage conditions that may affect drug quality. This paper presents an IoT-based smart pillbox designed to improve medication adherence and safety. The system uses RFID to identify scheduled doses, a load cell to confirm pill removal, and a temperature sensor to monitor storage conditions. A WiFi-enabled microcontroller sends real-time notifications to caregivers and logs intake data to the cloud for basic adherence analysis. By combining intake verification with environmental monitoring and adherence tracking, the proposed system provides reliable support for medication management in elderly care.
