Sensor network is a hot topic in resent and the applications for it are many and varied. Even it had been researched for long time, but there is always some new idea and new challenge put into which bring its holly green vigorous development in different period of researching. In this paper, based on preliminary study, basic concept, issue of sensor network and its research is given, based on analysis, several related idea and theory will also been discussed. A trial exploring utilization based on gray dynamic theory were discussed later and with its practice, the platform such as Tiny Os and some hardware issue for research and application has been introduced and discussed; therefore take a glance into the future about the work which is worth to do aiming at the challenge it faced now and might in tomorrow.
