针对温室中农作物的质量和产量受光照强度、温湿度和二氧化碳(CO_2)浓度的影响问题,提出了一种基于Wi Fi的温室环境检测与控制系统。该系统包括数据采集、数据传送和数据处理三个部分,使用STM32F103作为主控制器将传感器检测的温室光照强度、温湿度和CO_2浓度等信息,经由Wi Fi模块传送给PC机,管理者既可以远程查看温室作物的生长情况和环境信息,也可发送指令控制卷帘机、补光灯、遮阳板、洒水器和排风系统远程调节温室的环境。实验结果表明,该系统运行稳定、操作方便,能实时检测和调节温室环境。
Aiming at the problem that the quality and yield of crops in greenhouse are affected by light intensity, temperature and humidity and carbon dioxide (CO 2) concentration, a Wi Fi-based greenhouse environment detection and control system is proposed. The system consists of three parts: data acquisition, data transmission and data processing. The STM32F103 is used as the main controller to transmit information such as greenhouse light intensity, temperature, humidity and CO2 concentration detected by the sensor to the PC through the Wi Fi module. The administrator can either Remotely view the growth of greenhouse crops and environmental information, but also send instructions to control the shutter machine, fill light, sun visors, sprinklers and exhaust systems to remotely adjust the greenhouse environment. The experimental results show that the system is stable, easy to operate, and can detect and adjust the greenhouse environment in real time.
