Eka v1: Emergency call auto-register, an emergency warning system based on internet of things for intensive care patient at hospital

The emergency calling device for nurse is generally located in every ward of a hospital. It is an important facility for every inpatient. However, generally these devices are still in the form of conventional electrical components that uses long wiring. This is because this system must reach all inpatient rooms. In addition, the caller feature is also very limited, usually only in the form of an emergency button. The caller system is also not yet integrated with the hospital database, so it becomes an obstacle for nurses and doctors to understand the patient's condition in an emergency. This article discusses the design of a nurse calling device that is connected wirelessly via a wifi network on the ward. There are also several types of calling features so that the nurse or doctor immediately knows the type of assistance a patient needs. In addition, the client and server system is integrated with the hospital database, which shows a detailed patient history. This device uses the NodeMCU ESP 8266 board as a client and Raspberry Pi 3 as a server. The features placed on this device work well as a design and are successfully implemented for one ward per server.
