Abstract: In order to realize the intelligent control of pig house, an intelligent control system based on ZigBee wireless sensor network was developed with CC2430 chip as the core, which could in real time collect and transfer temperature, humidity and concentration of NH3 data, and automatically control the door's status and the speed of exhaust fan, then the parameters of the pig house was adjusted. At the same time, it could realize remote and short range control through the M35 module and infrared module.
