Product Description

Abstarct – The system begins with the piezoelectric transducers, which generate a small voltage when compressed by footsteps. This AC voltage is converted to DC via a bridge rectifier and stored in a rechargeable battery through a charging circuit. An Arduino microcontroller acts as the central brain, constantly monitoring the battery levels; it displays the current storage status on an 16×2 LCD and illuminates LED indicators to show power availability. To prevent unauthorized use, the system remains in a locked state until a user swipes a Smart RFID card. Once the RFID reader validates the card, the Arduino triggers a relay module that activates the mobile charging port and a DC water pump for the drinking water dispenser. The LCD provides real-time feedback during the transaction, such as “Access Granted” or “Charging Active.” This setup ensures that the harvested “green” energy is managed efficiently and dispensed only to registered users.
