And the safety of grain benefits more to the national economy and the people’s livelihood. Food safety is connected with harmony and stability of the society and the sustainable development of the economy. However, traditional detection system of grain situation is influenced by conductor resistance and distributed capacitance, measurement error is larger and it is easy to be stroked by lightning. Due to these defects mentioned above, it is significant to design detection this system of grain situation on the basis of the technology of ZigBee. This system can play an important role in ensuring the safety and storage of grain and be likely to benefit for economy and society. This system uses CC2530 as key chip and bines with ZigBee protocol stack, which adopts DH11 digital temperature and humidity sensor as the sensor of the system, LCD12864 as display interface. The realtime munication between principal puter and single chip achieves the display of temperature and humidity in many spots. The whole design acplishes collection of temperature and humidity in the sensor node and delivers to the coordinator through wireless transmission and monitors in the LCD12864. After that, it delivers to the principle puter to display. In addition, the whole design can not only reveal the temperature and humidity of current points in the coordinator but also view records of the temperature and humidity of current point in the principle puters with the function of detecting faults of sensor nodes. This chapter systematically introduces the concept of sensor work and the feature and structure of this munication protocolZigBee designing scheme, and emphasizes on the detecting system and the designing scheme posed of CC2530 SOC chip and DHT11 digital temperature and humidity sensor. After that, it introduces the designing process of hardware circuit and the development process of systems software. Finally, it further states the development direction of wireless sensor work in the future.
