PROBLEM TO BE SOLVED: To measure an electromagnetic wave in environment simply and correctly. SOLUTION: An electromagnetic wave monitoring device 1 measures an electromagnetic wave intensity at the surrounding of the device by an electromagnetic wave measuring USB module 20 equipped with antennas 22-1 to 22-n and receiving circuits 23-1 to 23-n. Then, the electromagnetic wave monitoring device 1 stores the measured frequency and intensity of the electromagnetic wave into the electromagnetic wave state data base, and displays the state of concentration of carbon dioxide and oxygen based on the stored data. Therefore, the electromagnetic wave intensity in user individual's work environment can be measured with high accuracy. Also, the electromagnetic wave monitoring device 1 can compose the electromagnetic wave measuring module 20 by connecting the UBS interface 17 of PC, and can perform the measurement of the electromagnetic wave intensity simply.
