Abstract
Ultra-wide band (UWB) radar has received an increasingly concern for its unique ability in medical application. Much effort has been made to explore the feasibility of UWB radar to serve as a medical instrument. However, previous work hardly considered the issue of using UWB radar as a sensor node in wireless sensor networks (WSN). To implement the integration of life detection sensor and WSN, we designed the interface circuit to connect our UWB sensor with the ZigBee module and defined the interface communication protocol. The results showed that the UWB sensor node can communicate with the other nodes in WSN. The integration is of great significance in that, at earthquake-stricken area, we can use the system to quickly establish the WSN and carry out the rescue without depending on the surrounding environment.
