Research on Temperature Monitoring Technology for Smart Agricultural Greenhouses Based on Wireless Sensor Technology

The rapid development of mobile internet technology provides technical support for the automation and intelligence of agriculture. Smart agriculture based on mobile internet technology is a new direction for agricultural development in China. This paper focuses on the application of mobile internet technology in smart agriculture, introduces and analyzes the application of ZigBee wireless sensor technology in smart agricultural greenhouse temperature monitoring systems, and designs a highly applicable agricultural greenhouse temperature monitoring solution. In this solution, the entire monitoring system mainly consists of four parts: a ZigBee wireless sensor monitoring module, a ZigBee coordinator + GPRS wireless gateway communication module, a Web server, and a mobile phone monitoring client. The ZigBee wireless sensor monitoring module collects greenhouse environmental information and transmits it through the ZigBee network to the ZigBee coordinator + GPRS wireless gateway communication module. The gateway communication module uses the GPRS network to establish data links with mobile or China Unicom base stations, and then transmits the environmental information data to a remote Web server through these base stations. The Web server analyzes and stores the data, and users can use a browser on a PC or a mobile phone APP to intuitively and conveniently observe the real-time environmental data in the greenhouse and query the change curves of greenhouse information based on historical records. This solution supports real-time query and monitoring of greenhouse environmental information, and also supports users to remotely control greenhouse equipment according to the growth stage of crops and the environmental parameters of the greenhouse.
