基于云平台的PWM智能LED补光方法研究
PWM Intelligent LED Lighting System Research Based on the Cloud Platform
摘要
Abstract
Based on different plants to the needs of environmental light quality, light intensity, light cycle and various needs, we propose a cloud platform for remote monitoring and short-range wireless dynamic LED dimming approach.Mobile client realizes to set red and blue light illumination threshold, using pulse width modulation (PWM), making environmental light intensity and threshold tends to be consistent by the dynamic cycle regulation using two wireless NRF24L01 modules and red, blue light deviation respectively in less than 5 lx and 1 lx, Meanwhile, the real-time monitoring of temperature and relative humidity in the greenhouse.The system has distance adjustable between the plants fill position and LED light source, high precision, simple operation, saving manpower, etc, it has broad prospects for development.关键词
