On the basis of analysis on feature of WSNs

a new kind of multi-use hardware node based on widely applied MCS—51 MCU is designed

it can collocate with multiple wireless RF module

design idea and method are described

material object product is fabricated according to design requirement

and three kinds of parameter

power consumption

wireless data transmitting distance and packet loss ratio are evaluated.When Si4432 RF module is used during the test

the max power support is only 280 mW and wireless communication distance is120 m

packet loss rate is 0.667 %.Hardware test result shows that the design of platform is flexible

power consumption is low

which meets the requirement of design of WSNs hardware node

so the platform has practical value.
