The main aim of this project is to design and develop a Smart Saline Level Monitoring System using a Load Cell Sensor and GSM technology to continuously monitor the saline level and alert healthcare staff when the saline bottle is nearly empty. In hospitals, patients receiving saline require continuous monitoring to prevent complications caused by the completion of saline without timely replacement. This system helps reduce manual monitoring and improves patient safety. The main controlling device of this project is an Arduino UNO microcontroller. A load cell sensor is attached to the saline bottle to measure its weight and determine the remaining saline level. The measured data is continuously processed by the Arduino and displayed on an LCD. When the saline level reaches a predefined minimum limit, the GSM module automatically sends an alert message to the registered mobile number, informing the nurse or caretaker to replace the saline bottle. The system is programmed using Embedded C language. This proposed system provides a simple, cost-effective, and reliable solution for saline level monitoring in hospitals and healthcare centers, helping healthcare staff respond promptly and reduce the risk of saline depletion.          

The Objectives of the project:

1. To continuously monitor the saline level using a load cell sensor.
2. To measure the remaining saline quantity based on bottle weight.
3. To display the saline level on an LCD.
4. To send an SMS alert through the GSM module when the saline level is low.
5. To reduce continuous manual monitoring by nurses and caretakers.
6. To improve patient safety during saline administration.

         

The main blocks of this project are:

• Regulated Power Supply.
• Arduino Micro Controller.
• GSM module.
• Load cell.
• LCD Display.

         

Software’s used:

1. Arduino IDE Studio Compiler to write the program.
2. Embedded C language.
