An RSSI(Received Signal Strength Indicator) measuring method for the configuration of a wireless sensor network and a PRMD(Portable RSSI Measuring Device) are provided to grasp the communication environment exactly at a place expected to install a new communication node by detecting communication quality in actual communication with communication nodes of a wireless sensor network system at the expected place. A PRMD comprises a communication module(14), a display unit(16), a control part(10). The communication module performs communication with communication nodes of a wireless sensor network system. The control part transmits a communication quality detection request message to one or more of the communication nodes of the wireless sensor network system at a place expected to install a new communication node. If a response message containing transmission quality information is received from a communication node, the control part detects reception quality information for the received response message. Also the control part displays the detected reception quality information and the transmission quality information, contained in the received response message, through the display unit.
