Abstract
The present disclosure relates to a sunlight-adaptive intelligent irrigation system based on solar charging power detection and a method thereof. This system comprises a main control unit, a parameter setting module, a solar detection module and a drive execution module. By utilizes solar panels to detect electrical parameters to indirectly sense light intensity, the main control unit adaptively adjusts the irrigation amount accordingly. This addresses the issue of conventional timed irrigators being unable to adjust water volume based on sunlight conditions, thereby achieving water conservation and efficient irrigation.
