Abstract: Establishing greenhouse intelligent monitoring system can promote the modernization of solar greenhouse facility horticulture in northern China. Intelligent monitoring system of solar greenhouse is helpful for increasing the yield of facility horticulture and realizing the modern  management of solar greenhouse. According to the need for  agricultural environment data monitoring and environment control at solar greenhouse in northern China, this paper designed a set of intelligent monitoring system based on the control core of STM32 MCU to meet the solar greenhouse environment in northern China. This system combined sensor technology, automatic measurement technology and communication technology to capture, storage, display, monitor and control the temperature, humidity, illuminance, CO2 concentration in solar greenhouse, and also conducted linear regression analysis on those data collected from the greenhouse environmental factors. Thus, the real-time telemetry, remote adjustment and remote control of greenhouse environment were completed. At the same time, the history and data of environmental factors of each  greenhouse were also provided. The testing results showed that this intelligent monitoring system operated stably with  accurate and reliable measurement result and good extensibility, which could satisfy the need for control and has great application prospect.
