    Hospital patient monitoring has been transformed by the introduction of Internet of Things (IoT) technology, which provides real-time data collecting and analysis for improved patient care. To monitor and control intravenous (IV) drips given to patients in hospitals, this paper offers the Patient Drips Monitoring System (PDMS), which is based on the Internet of Things. The suggested system makes use of Internet of Things (IoT) sensors to continually track some IV drip-related characteristics, such as drip rate, volume, and drug concentration. Data is wirelessly transmitted by the Internet of Things sensors to a central monitoring unit, which processes the data instantly. Healthcare professionals can remotely access and simultaneously check the progress of IV drips for many patients using a web-based interface. By using clever algorithms, the system can identify deviations from predetermined thresholds and send out alerts.

    Key Components: Sensors, Data Processing Unit, Wireless Connectivity, User Interface, Alerting Mechanism.


    The use of technology has completely changed patient care in the current healthcare environment, improving overall service quality, accuracy, and efficiency. The Patient Drips Monitoring System is one such creative use case that makes use of the Internet of Things (IoT) to guarantee accurate and timely monitoring of hospitalized patients receiving intravenous (IV) drips. In hospitals, giving intravenous fluids, drugs, and nutrients is standard procedure. On the other hand, human error can occur when manually monitoring IV drips, which could result in issues like over- or under-dosing and seriously jeopardize patient safety. Conventional IV drip monitoring techniques entail routine nursing staff inspections, which might not offer continuous and instantaneous patient condition data. The Patient Drips Monitoring System uses Internet of Things (IoT) technologies to improve and automate the monitoring process in order to address these issues. This system combines wireless connection, data processing, and sensors to monitor IV drips continuously. It also

    notifies healthcare personnel in a timely manner if there are any anomalies or deviations from the recommended settings.


    Hospitals can use a variety of IoT (Internet of Things) components and technologies to implement patient drip monitoring systems. Here's a summary of the current approach:

    Sensors: To track variables including flow rate, volume infused, and drip status, Internet of Things (IoT) sensors are affixed to intravenous (IV) drip lines. These sensors can be pressure, flow, or optical sensors, depending on the particular needs and limitations of the application.

    Processor/microcontroller: A processor or microcontroller gathers information from the sensors. To take additional action, it

    temperature, drip rate, and liquid volume remaining.

    Control Algorithms: Create algorithms that utilize sensor readings to regulate how the system operates. For instance, set alerts or sirens to sound if liquid levels are dangerously low, or if you want to maintain the specified drip rate by modifying the relay switches that regulate the flow of drips.

    Communication with IoT Module: Integrated software will allow the Arduino controller and the IoT module to communicate with one another. For online platform or server-based remote monitoring and analysis, use protocols like MQTT or HTTP to send sensor data accumulation data.

    User Interface: The LCD's user interface can be made more user-friendly by implementing software. Give important details including liquid levels, drip rate, system condition, and any alerts or warnings. Provide buttons to allow users to engage with the system and do tasks such as verifying notifications or modifying drip settings.
