In order to overcome the limitations of wired sensor networks and the complex structure of motor

motor stator wingding temperature monitoring system design based on wireless sensor networks is proposed. On the basis of platinum resistance three-wire measuring temperature principle analysis

hardware design of sensor node based on programmable system on a chip（ PSoC） and Pt100 is given. It solved power consumption problem of wireless sensor networks well. The software design is introduced

including software of sensor nodes and Sink node. Error analysis and correction are also given and the experiment shows that the measurement accuracy is improved.
