Live Health Monitoring and Menace Detection Using Lifi And Blockchain Encryption

Extensive mines must always be built in inorder to satisfy the everlasting demand for coal and other renewable resources, putting thousands of people in perilous and unpredictable conditions. As technological advancements transpire at a much faster rate, hundreds of millions of gadgets are being connected to the internet for faster communication. Every tendency generates radio frequency congestion even though all wireless communications demand radio frequencies to effectively deliver the messages. As an alternative to WIFI, LiFi, a component of VLC, promotes wireless connection using visible light. LiFi is far less expensive than Wi-Fi since its hardware for data transmission and reception is substantially simpler. Moreover, VLC could offer far more secure communication because it is difficult to intercept. It is more suited to use VLC at such locations to facilitate quicker and safer communication because RF can interfere with signals originating from various equipment.Hence, LiFi can provide both the illumination and data transfer needed in such circumstances to save the lives of mine workers.
