1. A temperature sensing apparatus comprising:
a first voltage generator including a first resistor and a first temperature sensor;
a second voltage generator includes a third resistor and a second temperature sensor and configured to generate a control voltage in response to a temperature being sensed;
a voltage adjuster connected in parallel with the first resistor and configured to adjust a voltage applied to the first temperature sensor based on the control voltage; and
a controller, different from the second voltage generator, configured to sense the temperature based on at least one of the voltage applied to the first temperature sensor and the control voltage, and
wherein the first temperature sensor is a device configured to convert a temperature into a voltage, and
the third resistor and the second temperature sensor are configured to generate the control voltage applied to a switch included in the voltage adjuster, such that the switch is turned on/off in response to the temperature.
