CC2431 is used as the m i ropro essor in the system. T em perature, hum idity and sm oke sensor are used. And Z igBee proto ol is sele ted as theW SN transm ission proto ols to a h ieve a low-powerw ire- less sensor network node hardw are platform. And w ireless temperature m easurem ent expermi ent is om pleted using the designed sy stem. K ey w ord s: W SN, node, hardw are design [ 1-3] (W SN ), . [ 4-6] . , A /D .
