Say goodbye to frequent battery changes. This device is equipped with a sustainable dual-power system combining an efficient solar panel and a built-in rechargeable battery. For outdoor setups, the solar panel continuously captures daylight to cycle-charge the battery, ensuring uninterrupted operation. When used indoors, placing the sensor near a sunlit window for just a single day can provide enough stored energy to power the unit for nearly an full year, offering true maintenance-free convenience.
