And a wireless sensor network node device was implemented based on the ultralow power comsumption processor Atmega128 and the radio frequency chip CC2420 . This node device could do power monioring itself . It also could be used in many condition by exchange the data collection circuit which was connected to the universal hardware interface. Software modularization design was used in this paper and finit state machine was used to finish the system mode scheduling. An adapt-layer software was designed and implemented ,
