  "textContent": "A long-lifespan hybrid-powered asset tracking device with solar charging capabilities operable under high and low light irradiance conditions is provided. The device includes a system controller with power-saving management logic, a communication assembly, a battery assembly, a vibration sensor module, and an occupancy detection module. The communication assembly is coupled to the system controller and provides location determination and data exchange in indoor and outdoor environments. The battery assembly comprises a solar panel module, a primary battery module, and a secondary battery module for charging the secondary battery module using energy from the solar panel module and the primary battery module. The vibration sensor module cooperates with the power-saving management logic to limit data exchanges with a cloud server when no movement is detected. The occupancy detection module detects whether an object is present within a predefined perimeter and limits data exchanges when no objects are detected.",
