Abstract: Medication non-adherence and unauthorized access to prescription drugs continue to be two of the critical challenges that plague modern healthcare, often resulting in inefficient treatment, adverse drug events, and avoidable hospitalizations. This work proposes an IoT-enabled Smart Pill Bottle for controlled and timely medication intake in a monitored environment. This system includes embedded sensors, an ESP32-based control unit, and cloud connectivity, enabling real-time authentication of medication access and dose consumption verification. Sensor-based event detection, combined with automated reminders and notifications to caregivers, will permit continuous adherence monitoring and immediate response to missed or delayed doses. Tamper-detection mechanisms further recognize unauthorized access attempts and secure safety for controlled and high-risk medications. Cloud-synchronized logs and adherence analytics will present valid, timestamped data to caregivers and healthcare professionals to facilitate proactive intervention and evidence-based clinical decisions. The proposed solution provides significant improvement in medication safety while improving accountability and enhancing remote healthcare monitoring for elderly and chronically ill patients.
