In order to realtime and efficient collection of temperature and humidity data in the environment, this paper uses a TinyOSbased wireless sensor network data acquisition platform, the use of cc2538cb as a sensor node, the use of the blip protocol initially complete the application of temperature and humidity monitoring program development, to achieve the pointtopoint communication, and the use of polling service as a basis for the development of pointtomultipoint communication. In the experiment process, by placing multiple sensor nodes in different experimental environments, according to the situation that each node collects data in different environments, it is proved that this kind of design method can cope with the change of environmental factors, and can successfully complete the collection of temperature and humidity data in the environment also avoid the loss of data during transmission.
