Abstract

Adhering to the new concept of developing new energy and making full use of the abundant sunlight in daily life, this paper designs a home solar energy recovery power bank. It imitates the heliotropic characteristics of sunflowers by mounting the solar panel on a servo motor. A photoresistor senses the light intensity to identify the optimal angle of illumination, enabling the solar panel to remain perpendicular to sunlight at all times. In addition, auxiliary functions such as home environment detection, information interaction and display, and Q-style emoticon interaction are integrated into the battery pack. While maintaining the original functions of a power bank, these features add both interest and functionality to the device. When idle, this power bank fully harvests solar energy. It can not only supply power to electronic devices when necessary, but also serve as a home assistant to monitor the real-time status of the home environment.

Keywords
