Chinese Forest Frog is the precious frog species with edible and medicinal value. As of endangered species, Chinese forest frog breeding by greenhouse will become inevitable in recent years. But the canopy light, temperature, humidity and carbon dioxide content will directly affect the survival rates of frog, and it is also difficult to monitor the above parameters artificially. As a result, Chinese Forest Frog breeding greenhouse monitoring system based on ZigBee technology appeares.There is a trend in the environment monitoring system that is to apply the wireless communication technology to monitor the system. The ZigBee technology, which is a kind of bidirectional wireless communication technology, is applicable to the short distance cases, consumes less power and less money and can be easily realized. Using in the monitoring system of the greenhouse cultivating the Chinese Forest Frog, it has the advantages as follows:it don’t need field wiring, has the collecting node that has a flexible position, covers a wide area, can be maintained conveniently and so on.First this paper introduces ZigBee technology characteristics and monitoring system solution. In the hardware system design, the paper uses modular design method, including the wireless communication module, the data collecting module, the power supply module, the serial communication module and LCD module. In addition, Special sensor interface is reserved by extracting available I/O pins. In the software design, the paper designes some control commands to monitor sensor nodes, including Multi-Control methods (unicast, broadcast and multicast) and data Multi-Return methods (single and cycle), the paper also designes the data acquisition and processing, data upload part, minitoring management software in PC. And last the paper studies key problem for monitoring system.Based on ZigBee Technology, this paper eventually sets up a Wireless Sensor Network monitoring system. User can inputs some control commands to monitor a sensor node, the part of all nodes or all nodes in the monitoring environment, and user can also monitor water temperature, humidity, temperature and light abovewater in PC. Test result shows that the system is more flexible, more accurate. What’s more, it also provides a new solution for an intelligent greenhouse monitoring system.
