Design of LED Intelligent Light Supplement System Based on STM32
Abstract— The artificial light plays a key role in the process of crop growth, the existing light supplement system lack condition on the light intensity controlling and variation of light demand in different stages and conditions. This paper presented a LED intelligent light supplement system, based on STM32 MCU to realtime monitor light intensity of specific light spectrum, and utilized PWM signal to adjust the light intensity to meet the demands of supplementary. The testing results showed that this intelligent light supplement system was reliable, accurate and could provide light supplement in crop growth.
Index Terms— LED light source; supplementary lighting system; STM32; PWM.
