| 摘要 |
<p>The present invention proposes an apparatus for measuring temperature, comprising: a processing unit, which has a parameter of temperature sensor type therein, and said processing unit controls a first analog switch to connect to a first current source when the value of said parameter of temperature sensor type has the value for a first signal type; a detecting unit for measuring the voltage drop caused by a current generated by said first current source flowing through said temperature sensor; and a comparing unit for comparing said voltage drop with a first voltage range, wherein if said voltage drop is within the first voltage range, then said temperature sensor is of a first temperature sensor type and temperature is measured by said first type temperature sensor; otherwise said temperature sensor is of a second temperature sensor type and temperature is measured by said second type temperature sensor.The apparatus for measuring temperature of the present invention has an internal mechanism for automatically identifying a sensor, and is capable of implementing temperature measurement without switching a code switch.
