ZigBee/GPRS Wireless Agriculture Monitoring System I. Project Background With the continuous development of science and technology, agriculture has also entered the ranks of technological development. In the past ten years, greenhouse cultivation has brought great convenience to people's living standards and has been rapidly promoted and applied. In the freezing winter. There are certain requirements for the planting environment in greenhouses. Greenhouse temperature, humidity, light intensity, CO2 concentration and other environmental factors have a great influence on the production of crops. Through RY-C04-type temperature + humidity + light + CO2 concentration sensor device, the various data in the greenhouse will be transmitted to the computer software platform. In order to control the greenhouse management. According to the current trend of greenhouse development, a design of a greenhouse intelligent monitoring system is proposed. According to the special characteristics of the greenhouse intelligent monitoring, it is necessary to transmit the on-site parameters of the greenhouses to the managers so that the upper-level departments can understand the real-time conditions of the regional greenhouses through the Internet or mobile phone information at any time. The GPRS-based intelligent greenhouse monitoring system makes these possible. II. Solution analysis 1. System components 2. Greenhouse site acquisition control terminal Greenhouse site acquisition control terminal is responsible for 24-hour sampling of greenhouse temperature, humidity, light, soil temperature, soil moisture, CO2 Concentration, dew point temperature and other environmental parameters. 3. The wireless transmission equipment uses GPRS/ZIGBEE/433 and other wireless methods for data transmission to complete the transmission and reception of information. Physically as shown in Figure 1 ZigBee/433 receiver. Physical object shown in Figure 2 4. The data management center data center analyzes and processes environmental parameters such as temperature, humidity, light, soil temperature, soil moisture, CO2 concentration, and dew point temperature collected in real-time on the site, and not only completes statistics, but also makes corresponding statistical reports. And make trend analysis, and display it to the user in intuitive charts and curves. 5. The overall system architecture is shown in Figure 3.

5. System implementation function 1: It can continuously collect and record the temperature, humidity, wind speed, carbon dioxide, light, and other parameters of the monitoring point in real-time 24 hours online. It can be displayed in real time through digital, graphics, and images. And record storage monitoring information, monitoring points can be expanded. 2: temperature and humidity monitoring software interface, real-time display, record the temperature and humidity values ​​and curve changes at each monitoring point, statistical data of temperature and humidity data, the maximum, minimum and average, cumulative data. 3: The monitoring host can use the monitoring software to print the temperature and humidity data and running reports at any time. 4: Powerful data processing and communication capabilities, using computer network communication technology, any computer in the LAN can access the monitoring computer, online to view the temperature and humidity changes of the monitoring point to achieve remote monitoring. Not only can the system be monitored in the duty room, leaders can easily watch and monitor in their own office.
The following figure shows the background center management software: 
3. Summary The application of planting agriculture sheds has become more and more extensive, and high-efficiency agricultural production has been achieved. With wireless remote monitoring systems, it has solved the phenomenon of difficult maintenance of greenhouse cultivation. The application of wireless remote monitoring has been fully reflected in the field of greenhouse planting. It is believed that the application of wireless monitoring will also be applied more in other areas, and the value of the Internet of Things is constantly reflected.
