摘　　要：本文以单片机STC89C52为核心构建草莓大棚红蓝LED补光系统。该系统使用数字环境光传感器BH1750和数字温度传感器DS18B20采集光照和温度,通过单片机输出PWM信号调控PT4115的输出电流,从而控制LED组合灯的补光强弱,并通过延时控制算法控制继电器的通断,实现温度的补偿,最终控制光照和温度达到草莓光合作用的最佳条件。整个系统不但成本低廉,而且使用范围广,可应用于其他动植物大棚。The paper designs strawberry greenhouses red and blue LED light system based on microcontroller STC89C52. In this system digital BH1750 ambient light sensor and digital temperature sensor DS18B20 are used to collect the data of light and temperature, PWM signals is outputted to control current of PT4115 by MCU. The time delay control relay on- off control algorithm is applied to realize temperature compensation through controlling the light intensity of the LED combination lights. Finally light and temperature control achieves the best condition of strawben＇y photosynthesis. The whole system not only has low cost, but also wide using range, can be applied to other animal and plant greenhouses.
