In this paper, the authors propose an automatic, low cost saline level measurement system using microcontroller ATMEGA 328.The main building blocks of the proposed system are microcontroller ATMEGA 328, Bluetooth module and IR sensors. The system contains two LEDs. The status of the saline can be given in two forms that are normal status and warning status. When the saline level is normal, then green LED blinks and when the saline level is below the critical value then red LED will blink. When red LED blinks then buzzer starts ringing and nurse will get notification through mobile with the help of Bluetooth module.
