Health Care Assistive System in Hospital for Doctor to View the Patient’s Parameter in a Cloud Database using Light Fidelity

In hospitals, conventional or wireless fidelity (Wi-Fi)-based equipment continually monitor patients’ health state. Because of the rising number of approaches used, the Wi-Fi-based strategy is sluggish. Light fidelity (Li-Fi) identifies the places where Wi-Fi is applicable in this case, with increased high-speed data wireless modems. Aside from the pace aspect, Li-Fi is better suited in hospital operations for tracking the state of individuals despite human body periodic involvement. In this suggested system, we have constructed a LiFi-based patient health monitoring system with a high data-receiving speed. Whereas under the current system, the sensors may be physically checked by physicians or other specialists, this takes too long. This article demonstrates the usage of a healthcare Li-Fi system to record clinical variables such as temperature, pressure, pulse, hypoglycemia, and breathing issues using appropriate sensors. The sensor data is sent to the sink and evaluated using the microcontroller before being shown on the monitor screen in the form of tables and graphs.
