IoT Based IV Pole Monitoring System

This project focuses on the development of an interface with Arduino to monitor various aspects of patient care. The system incorporates multiple sensors, including a load cell to monitor saline levels, a temperature sensor to track patient temperature, and a pulseoximeter to measure heart rate and blood oxygen levels. The system provides audio and visual feedback through a buzzer and LCD display, respectively, and uploads the collected data to a web server for further analysis and remote monitoring.

The load cell module is designed to determine the level of saline in a bottle. By connecting a load cell to the saline bottle, the applied weight of the bottle is converted into an electrical signal. This enables monitoring of the saline level, and an alert is generated when the level drops below a predetermined threshold. The temperature sensor module enables monitoring of the patient's body temperature. By integrating a temperature sensor with Arduino, the system can measure and track temperature variations.

To measure heart rate and blood oxygen levels, a pulseoximeter is employed. The pulseoximeter is connected to the Arduino via an ESP8266 NodeMCU.  All the gathered data is uploaded to a web server via another NodeMCU, enabling centralized storage and remote access. By leveraging this data, healthcare providers can access patient records and track their progress over time. Moreover, the remote monitoring capability reduces the workload on hospital staff, allowing them to focus on critical tasks and respond promptly to emergencies.
