All most in all hospital, and nurse is responsible for monitoring the electrolyte’s bottle level. But unfortunately most of the time, the observer may forget to change the bottle at correct time due to their busy schedule .To overcome this critical situation, a IoT based automatic alerting and indicating device is proposed where sensor is used as a weight sensor. It is based on the principle that the sensor output changes when fluid weight is below certain limit. When Fluid weight is low, will alerts the observer through the display or/and mobile phone at the control room indicates the room number of the patient for quick recovery Hospital uses simple electrolytes bottles with no indication, it may create a problem to patient because the reverse flow will start, blood start to flow from body towards bottle. In, Hospital ICU, CCU, NICU most of all department of hospital required such kind of automatic monitoring and indication system. Also Health care industries will one of the users. Such monitoring system can be useful in small, medium and large size of hospitals and also it useful during home care. If such a monitoring system builds, it will decrease the chances of patients hazards and increases the accuracy of health care in hospital. Such data can also send to nurses and/or doctor`s mobile and they can start or stop the fluid and also monitoring fluid condition, such things required security password also. Hospital staff, the constant need to manually monitor the level of bottles is avoided. This is of high advantage to the patients especially during night times. This system also avoids the fatal risk of air bubbles entering the patient’s bloodstream, which is a serious threat as air bubbles in blood can cause immediate death. Such a device will create assurity of non-harm condition to patients. Key Words: Weight sensor, load cell, electrolyte bottle, air bubble, indication system. 1. INTRODUCTION Saline solution is used in the hospital whenever some energy needs to be supplied to the patient in form of liquid. But there are some issues with this saline injection process. As there is more quantity to be injected it takes time to complete this process. In this injection process, continuous monitoring is required, where it is difficult in many hospitals. The monitoring staff may forget about the patient. This forgetting may result in serious danger to the patient. when the saline bottle is about to empty the blood from the body of the patient flows back into the bottle. This flowing back of blood causes serious damage to the patient. The patient might be in a situation of unable to check his own saline bottle level. 1.1 Site visited We have visited Chinmayi Hospital, Kankipadu. They were having a serious problem regarding the continuous monitoring of the infusion bottle. They also have cases where backflow has happened. we have identified this problem as the major issue they were facing. We have interacted with the hospital Management team and with some of the Doctors and Nurses. After a healthy discussion with the hospital staff, we came to know what problems they are facing frequently. We found that there are some problems that are needed to be eliminated in order to provide proper patient care in hospitals as patient care is a crucial part of the hospital sector. So we concentrated more on the problems that affect patient care. 2. LITERATURE REVIEW By using a rubber band mechanism in which rubbers are used and variuos software as well as hardware is used. The rubber band mechanism helps to easily detect the levels of saline water and the LED lights of the IR sensor glows accurately at each level of the saline bottle. Firstly while the saline bottle is feeded to the patient, the starting level will be completely full so the obstacle will cut the light rays of first IR sensor and the first LED of the IR sensor will be glown and the automatic alert message of partially filled bottle will be sent to the nurse [1]. This paper highlights RF based automatic alerting and indicating device where IR sensor is used as a level sensor.IR sensor output voltage level changes when intravenous fluid level is below certain limit. The comparator continuously compares the IR output with predefined threshold. When the transceiver output is negative then the Arduino controller identifies that the
