<P>PROBLEM TO BE SOLVED: To ensure reliability of a temperature sensor detecting a temperature. <P>SOLUTION: A temperature measurement device 20 includes a first temperature sensor 21, a second temperature sensor 22, and a temperature detection control circuit 200. The temperature detection control circuit 200 obtains a temperature change in a prescribed time length from a temperature detected by the first temperature sensor 21 and determines whether or not the temperature change is greater than a threshold value. When the temperature detection control circuit 200 determines that the temperature change is greater than the threshold value, it sets a signal S2 at an H level to bring the second temperature sensor 22 into an active state. When the temperature detection control circuit 200 determines that the temperature change is less than or equal to the threshold value, it sets a signal S1 at an L level to bring the second temperature sensor 22 into a non-active state. <P>COPYRIGHT: (C)2013,JPO&INPIT |
