Today people pay more and more attention to environmental protection， to environmental pollution， noise pollution is a study of people healthy has very big Through the noise monitoring of data can be collected regularly， so understand promptly site conditions， in order to control noise pollution and may be used to This paper studied a method based on wireless sensor network noise monitoring This paper firstly wireless sensor network noise monitoring overall structure made a general introduction to a wireless sensor network， then the system structure and ZigBee network transmission agreement makes a detailed explanation， and introduces ZigBee transport protocol principle， the topology of the network， ; Then completed based on wireless sensor network noise monitoring scheme design， including the hardware design and software design two aspects， in order to qualify as a sensor network of the low power， little volume requirements， this design USES the CC2430 as the controller chip， using ZigBee agreement， through the mesh principal-subordinate nodes of data collection and transmission， and use serial communication and superordination
