Power Consumption of LED-Based LiFi Transmitters

Efficient energy monitoring and wireless communication systems are important in modern smart electrical applications. This project presents a Power Consumption Monitoring System for LED-Based LiFi Transmitters using Arduino and LiFi communication technology. The proposed system uses a PZEM sensor to monitor electrical parameters such as voltage, current, power consumption, and power factor. Two LED bulb loads of 100W and 200W are used to analyze variations in power consumption under different operating conditions. LiFi technology is used for wireless data transmission through visible light communication between the transmitter and receiver sections. LCD displays are used to show monitored electrical parameters and system conditions continuously. During abnormal electrical conditions or excessive power usage, the system activates a buzzer and a red LED indicator for alert notification. At the same time, LiFi communication transmits the abnormal condition data from the transmitter to the receiver section for monitoring and analysis. The system is powered using dual adapter power supplies for stable operation. The proposed system supports efficient power monitoring, abnormal condition detection, wireless LiFi communication, and smart energy management applications using visible light communication technology.
