Action note: In: Summary: ABSTRACT: The present comprehensive study aims to develop and optimize a piezoelectric energy harvesting system with real-time monitoring using IoT. The primary objectives are to achieve efficient energy conversion drawn with energy storage, enable monitoring in real-time and conduct detailed analysis. Through experimental tests, the system demonstrates a dependable 5 V or higher output, making it suitable for powering various devices. By increasing the number of transducers, the system's current can theoretically surpass I A, providing an emergency power source. To enhance electrical output without compromising durability, the study explores techniques to apply additional stress to the pad chassis, such as introducing a hole and rubber contact. In regard to application of the PED, the study examined three locations on a university campus: Location 1 (Entrance of the PLM), Location 2 (Catwalk to Library), and Location 3 (Catwalk to Gusaling Lacson). Location 1 has an average current of 0.61 mA, a range of 1mA to 0.30 mA, and a voltage range of 9.98 V to 6.38 V. Location 2 shows similar patterns with an average current of 0.53 mA, a range of 0.8 mA to 0.40 mA, and a voltage range of 9.7 V to 2.33 V. Location 3 has an average current of 0.53 mA, a range of 0.7 mA to 0.40 mA, and a voltage range of 9.15 V to 3.55. In addition to the above, the present study incorporates the use of an INA219 current sensor and an ESP8266 Wi-Fi module. The INA219 enables accurate current measurement and monitoring, contributing to real-time analysis capabilities. The ESP8266 module facilities wireless communication and data transfer to a cloud-based server, enabling remote monitoring and control of the energy harvesting system, these electronic components enhance the system's functionality and enable Internet of Things capabilities, allowing for efficient monitoring and control of the energy harvesting system.
