PURPOSE:To enable a highly accurate estimation of a temperature being measured for a short time by computing and indicating the final arrival temperature before the temperature is stabilized from measured data in several intermittent measurements of temperatures. CONSTITUTION:A temperature sensor is built into a small electronic apparatus such as electronic time piece measures the water temperature and the room temperature through an electronic device. To achieve this, the temperature sensor 10 is operated to perform samplings several times at a certain interval with a sampling circuit 11. A measured data is converted into a digital value with a temperature measuring circuit 13 and an A/D converter 14 and the subsequent three data are stored sequentially into latches 16-18 with a distributor 15. The three data are inputted into a computation circuit 19 to estimate the final arrival temperature which is stored into a latch 20 and compared with the newest data of the latch 18. If within an allowable range, they are indicated on a display 28. |
