Aiming at the need for monitoring the environmental nuclear radiation in some areas a design scheme for a wireless sensing monitoring (WSN) system based on ZigBee is proposed. A CC 2530 chip from the TI company is used as the core, it together with a PC host constructs the hardware platform of the system network. The WSN monitoring system can monitor not only the radiation dose ofγrays, but also the temperature and humidity, rainfall and other atmospheric parameters, thereby realizing the data collect...
