Environmental control system based on IOT for nursery pig house

The microclimate environment in nursery pig house is important. In this thesis, an environmental control system based on internet of things (IOT) for nursery pig house was designed. In order to adjust the local microclimate environment in precise, wireless network of equipments like sensors and electronic hot plates were constructed. The network was based on ZigBee protocol. ARM embedded web server was used as control center. Management operation could extend from remote user into the nursery pig houses to realize the exchange of information between the environment and devices, as well as between the environment and remote user. B/S (Browser/Server) structure was used in the system, which could greatly simplify the client computer load and reduce system maintenance. The experimental results showed that the performance of the system was quite stable and the system satisfies the design requirements in real-time data acquisition wirelessly, environmental automatic control and environmental visualization control remotely. The monitoring system is suitable for precision environmental management for nursery pig house and has a good application prospect in automatic and intelligent livestock breeding industry.
