Abstract: Intravenous drug and fluid administration is one of the most common hospital procedures, yet many healthcare settings still depend on manual regulation using roller clamps and visual drip counting. Although simple and inexpensive, this approach is prone to human error, delayed intervention, and inconsistent flow delivery, particularly when one nurse monitors multiple patients. Existing IV monitoring systems alert staff to empty bottles or when pre-determined thresholds are met, but do not generally modify infusion rates or calculate patient-specific dosage requirements in real time. The present invention, Smart IoT-Based Drug Delivery System using Arduino and ESP32, addresses this limitation by providing a low cost automated prototype that calculates the required infusion rate based on patient-specific parameters such as body weight and prescribed dosage, measures actual liquid flow using a flow sensor, and automatically adjusts pump speed through closed-loop control. The Arduino Uno handles computation and control and the ESP32 does wireless IoT based monitoring. OLED display indicates target flow rate, actual flow rate and total volume delivered. The proposed system combines dosage calculation, real-time flow sensing, closed-loop control and remote monitoring into one platform, offering a practical smart healthcare solution for improving the consistency and safety of intravenous therapy.
