LIFI Based Sensor Data Monitoring System Electronics Engineering Final Year Project

Arduino interfaced with LIFI module through UART communication. LM35, MQ2 and IR sensors are connected to Arduino analog and digital pins respectively. Other side of LIFI module connected to PC or laptop serial port.

WORKING:

Here there are two LIFI sections. LIFI transmitter has sensors and LED light. Arduino sends all sensors data to LIFI module through serial port. LIFI converts digital data into light format and sends through LED array. At LIFI receiver solar panel receives data and signals will be amplified by LIFI module. Also it sends all sensors data to PC through UART port. We can monitor sensors data in PC through LIFI wireless communication.
