Abstract	This paper introduces an innovative IV Fluid Bag Monitoring, Alert and Control System Using ESP32 and IoT designed to address critical challenges in traditional IV therapy. The system uses an ESP32 microcontroller to monitor the weight of an intravenous (IV) fluid bag in real time via a load cell and HX711 amplifier module. A 16x2 LCD display provides continuous visual feedback of the IV bag’s status, while a Blynk-based mobile application ensures remote monitoring capabilities for healthcare providers. When the fluid level drops below a critical threshold, the system triggers visual and audio alerts, sends notifications to the medical staff, and automatically stops IV flow using a solenoid valve to prevent air embolism and other complications. This cost-effective and scalable solution aims to improve efficiency in clinical settings by minimizing human error and enabling timely medical interventions
