A Hybrid Solar Powered Wireless Charging System with IoT

ThisprojectpresentsaHybridSolarPoweredWirelessChargingSystemwithIoTMonitoring, aimedatpromoting sustainable and efficientenergyutilization.Solarenergyisharvestedusing a photovoltaic panel and stored in a lithium-ion battery bank through a regulated charging mechanism.Thestored energy is used to power two independent wireless charging platforms. Loadpresenceoneachwirelesschargingpadisdetectedusinginfraredsensors,allowingpower to be supplied only when a device is placed on the transmitter, thereby reducing energy wastage. An ESP32 microcontroller controls the relays, sensors, and display system, while audible alerts indicate load detection and charging initiation. A 16×2 LCD provides real-time system status, including battery charging information based on solar availability. The system also incorporates IoT functionality using the Blynk platform to remotely monitor parameterssuchastemperature, humidity, solarvoltage,andwirelesspadstatus.Byintegrating renewable energy harvesting, battery storage, wired power conditioning, and wireless power transferwithinanIoT-enabledframework,theproposedsystemdemonstratesapracticalhybrid charging solution suitable for educational and low-power charging applications.
