Since weather conditions may affect astronomical observation greatly, it is necessary to build a meteorological observation station near a telescope, but conventional meteorological stations usually adopt the wired data transfer mode, which is of many disadvantages, such as complexity in the wiring system and installation. The characteristics of ZigBee technology and the design of a wireless meteorological observation based on the ZigBee JN5139 Module are introduced. The system has been tested for several times. The results indicate that the meteorological observation system is easy to use, maintain, and expand, and performed well in various kinds of weather, such as raining, snowing, and high winds.
