Design of Adaptive Lighting Control System for Blueberry Planting Environment

Aiming at problems of light adjustment and low efficiency of blueberry planting environment illumination，an adaptive lighting system of blueberry planting environment was developed.The system included lower computer and upper computer in two parts.The lower computer took the STM32 single-chip microcomputer as its core and detected the light intensity through the BH1750 light sensor.The detection range could reach 1-65535 Lx，and the output could be adaptively changed according to light of external environment.The PWM signal could be adjusted by PID algorithm to drive large power LED illuminator to fill light.The upper computer was run on the LabVIEW platform developed monitoring software，real-time display of light intensity values and related data statistics and curve depicting.After test，the system could meet requirements of low-power operation for a long time，and promote growth of blueberries，which could provide technical reference for dynamic supplement of other crops.
