In view of a series of problems existing in the domestic greenhouse monitoring system

such as incomplete monitoring and low level of intelligence

based on the existing greenhouse technology

a greenhouse management system based on cloud platform is proposed.Relying on STM32 F103 RCT6 hardware platform

the system monitors the inner environment data of the greenhouse in real time through the sensors and cameras at the acquisition end

and sends the monitoring results to OneNet cloud platform through the 4 G module ML302.The farmers can view the environmental conditions of the greenhouse anytime and anywhere through App client.When the environment in the greenhouse is abnormal

proportional-integral-differential（PID）algorithm can be used to control the equipment at the execution end to automatically adjust the environmental data in the greenhouse.If necessary

it can be manually adjusted by the client to meet the environmental requirements for the growth of crops in the greenhouse.
