IoT IV Bag Monitoring and Alert System

This guide will help you create an IoT IV Bag Monitoring and Alert System to ensure timely monitoring and alerts for IV fluid levels. The system will use sensors to monitor fluid levels and send alerts to healthcare providers when the fluid levels are low or other issues are detected.

Components Required

• Microcontroller (e.g., Arduino, ESP8266, ESP32)
• Ultrasonic sensor (for measuring fluid levels)
• Wi-Fi module (if not integrated with the microcontroller)
• Buzzer or alarm system (for alerts)
• Power supply (battery or USB power source)
• Cloud service account (for data storage and alerts)
• Connecting wires and mounting materials

Setting Up the Hardware

Follow these steps to set up the hardware:

1. Connect the Ultrasonic Sensor

   Attach the ultrasonic sensor to the IV bag to measure the fluid level. Connect the sensor's output to the microcontroller's input pins. Ensure the sensor is properly positioned to accurately measure the fluid level.

2. Integrate the Microcontroller

   Connect the microcontroller to the ultrasonic sensor and the Wi-Fi module. The microcontroller will process the sensor data and handle communication with the cloud service.

3. Set Up the Buzzer

   Connect the buzzer or alarm system to the microcontroller. This will be used to alert healthcare providers when the fluid level is low or if there is an issue with the IV bag.

Programming the Microcontroller

Write code for the microcontroller to read the ultrasonic sensor data, determine the fluid level, and send alerts. Here’s an outline of the code:

                #include <Ultrasonic.h>
                #include <WiFi.h>
                #include <HTTPClient.h>

                const int trigPin = 9;
                const int echoPin = 10;
                const int buzzerPin = 11;
                const float lowLevelThreshold = 10.0; // Fluid level in cm to trigger alert

                Ultrasonic ultrasonic(trigPin, echoPin);

                void setup() {
                Serial.begin(9600);
                pinMode(buzzerPin, OUTPUT);
                WiFi.begin("your_SSID", "your_PASSWORD");
                }

                void loop() {
                float distance = ultrasonic.read();
                Serial.print("Fluid Level: ");
                Serial.println(distance);

                if (distance < lowLevelThreshold) {
                    digitalWrite(buzzerPin, HIGH); // Activate buzzer
                    sendAlert(distance);
                } else {
                    digitalWrite(buzzerPin, LOW); // Deactivate buzzer
                }

                delay(5000); // Wait 5 seconds before next reading
                }

                void sendAlert(float fluidLevel) {
                HTTPClient http;
                http.begin("https://api.yourcloudservice.com/alert");
                http.addHeader("Content-Type", "application/json");
                String payload = "{\"fluid_level\":\"" + String(fluidLevel) + "\"}";
                int httpResponseCode = http.POST(payload);
                Serial.print("HTTP Response Code: ");
                Serial.println(httpResponseCode);
                http.end();
                }
            

This code initializes the ultrasonic sensor, reads the fluid level, and sends an alert to the cloud service if the level is below the threshold. The buzzer is activated to alert healthcare providers.

Setting Up Cloud Alerts

Configure your cloud service to receive data from the microcontroller and trigger alerts. You can use services like AWS IoT, ThingSpeak, or custom APIs. Ensure the service can handle incoming data and send notifications as needed.

Testing and Calibration

Before deployment, test and calibrate your system:

1. Test the Ultrasonic Sensor

   Verify that the sensor accurately measures the fluid level and that the data is correctly read by the microcontroller.

2. Check Alert Functionality

   Ensure that the buzzer activates when the fluid level is low and that alerts are sent to the cloud service.

3. Calibrate Threshold Levels

   Adjust the fluid level threshold based on the requirements of your specific application.
