Abstract
A temperature measurement device is provided to measure an environment temperature and includes a thermistor, a resistor, a determination circuit, and a measurement circuit. The thermistor is coupled to a first node. The thermistor has a specific impedance value at a specific environment temperature point. The resistor has a first terminal coupled to the first node. The determination circuit determines a real impedance value of the resistor. The measurement circuit is coupled to the first node for receiving a measurement value signal generated at the first node and obtains a value of the specific environment temperature point according to the measurement value signal and the real impedance value of the resistor.
