The greenhouse system is based on Internet of things with sensor devices to detect temperature

relative humidity

light intensity

soil moisture

volume fraction of CO2 and other parameters.Datas collected by Zig Bee wireless sensor networks（WSNs） and then transmitted to remote monitoring center through wireless gateway which is based on STM32F103RBT6.Message warning can be carried out in greenhouse environment by analysis of received parameters

and PC or mobile phone terminal can get real-time state information of greenhouse and remote control irrigation device

natural ventilation

shading and other equipments of greenhouse realize intelligent management include automatic monitoring and automatic control.
