IoT-Based Automated Saline Monitoring and Alert System Using NodeMCU

  • Unique Paper ID: 182507
  • PageNo: 2411-2415
  • Abstract:
  • With the rising global population, the demand for efficient healthcare systems is increasing rapidly. In hospitals, one of the most common and essential treatments administered is intravenous (IV) saline therapy. However, manually monitoring saline levels is time-consuming and often leads to human errors, such as allowing the saline bottle to empty completely, which can cause serious complications including backflow of blood. To address this issue, this paper presents an IoT-based automatic saline level monitoring and alert system using NodeMCU Wi-Fi technology. The system employs an ultrasonic sensor to continuously monitor the fluid level in the saline bottle. When the fluid level reaches a predefined low threshold, the system triggers an alert using LEDs and also sends a real-time notification to medical staff via Wi-Fi. The NodeMCU module ensures seamless communication and cloud connectivity, enabling remote monitoring and reducing the dependency on continuous human supervision. The system employs an ultrasonic sensor to continuously monitor the fluid level in the saline bottle in real- time. This solution is cost-effective, scalable, and enhances patient safety by minimizing risk due to delayed response. The integration of IoT technologies in such critical monitoring applications marks a significant step forward in the development of smart healthcare systems.
