The greenhouses are of wide distribution

incomplete sensor configuration

low monitoring data accuracy and poor adaptive adjustment ability. In order to solve these problems

a design of Internet of things（ IoT）agricultural greenhouse intelligent sensing and control system is proposed in distributed greenhouses. A method of applying fog calculation in distributed greenhouse environment sensing system is proposed and a fog computing model for smart greenhouse IoT is designed. In order to realize the intelligent sensing

device self-diagnosis and fog calculation functions of greenhouse environment information

the greenhouse environment intelligent sensing and control device is designed and developed. ATmega328 P-AU MCU core controller is used to independently design and develop the Arduino motherboard of the acquisition device

and combine with control terminals which uses ARM Cortex-A53 as core controller. realize functions of information intelligent sensing and control of greenhouse information

terminal self-diagnosis and fog calculation. Experimental result show that the designed greenhouse intelligent sensing and control system has stable performance and high precision

and has certain application and promotion value.
