After studying the research status of monitoring system for plant growth information, a system is developed with Kingview, VB and C to monitor soil temperature, soil moisture, air temperature, air humidity, Illumination and carbon dioxide. The system realizes real time monitoring, remote access, trend analysis and many other functions. Transmission distance is estimated by channel transmission loss model. Theoretical transmission distances are 1691.99m outdoor and 480.84m indoor. The real transmission distance is measured in the production base. The experimental communication distances are 1680m and 1520m in sunny and rainy day.

To solve the topology structure of a greenhouse environment-monitoring system and the ductility of joints, this study presents a design of a greenhouse-monitoring system based on the ZigBee wireless sensor network (WSN). The hardware and software designs of the network node are provided, and the process of the ZigBee network coordinator is elucidated. The system uses the microcontroller unit PIC18F4620CC2420 wireless transceiver module to send and receive data. Data from temperature and humidity sensors are collected using an inter-integrated circuit bus through the ZigBee network transmission to the monitoring platform. Test results show that the system has the advantages of having a simple structure, flexible nodes, and low power consumption. It can effectively monitor the temperature and humidity in a wireless environment. WSNs considerably help in greenhouse environment monitoring. The use of advanced technology to control greenhouse temperature and humidity can satisfy the optimum growth environment of greenhouse crops and effectively improve the yield and quality of crops. The application of WSNs in greenhouse monitoring is significant to the development of modern and precision agriculture in China.
