<P>PROBLEM TO BE SOLVED: To provide a water temperature measurement device capable of measuring only water temperature by adjusting a timing of temperature measurement to reliably eliminate air temperature measurement. <P>SOLUTION: A water temperature measurement device 110 of the present invention includes a buoy 210; a temperature sensor 214 that is provided on the outer surface of the buoy 210 and measures temperature; at least one detection means (a first water sensor 216) that determines whether the temperature sensor is in contact with the water surface in a state that the buoy is floated on the water; a measurement control circuit 218 that allows the temperature sensor to perform temperature measurement when the temperature sensor is determined to be in contact with the water surface by the detection means; and an information transmission part 222 that transmits water temperature information that indicates the measured temperature. <P>COPYRIGHT: (C)2012,JPO&INPIT |
