Abstract
A secure Li-Fi-based modern healthcare system using a body sensor network is designed for real-time patient monitoring with high-speed and secure data transmission. The system uses an Arduino UNO as the main controller, interfacing with multiple sensors such as a heartbeat sensor to monitor heart rate, a MEMS sensor to detect movement, an eyeblink sensor, and a Dallas temperature sensor for body temperature measurement. A GSM module is integrated to send alerts in case of abnormal conditions, while an LCD provides real-time feedback. The system operates with two main modules: a transmitter (TX) kit and a receiver (RX) kit, where Li-Fi technology ensures secure and reliable communication between them.
