1. An ear thermometer with an improved temperature coefficient comprising:

  • infrared radiation sensor means for sensing an infrared radiation from a target and generating a first electronic signal;

    temperature sensor means for sensing a temperature of the infrared radiation sensor means so as to use the temperature as an ambient temperature and generating a second electronic signal;

    analog/digital signal converting means connected to the infrared radiation sensor means and the temperature sensor means for converting the first electronic signal and the second electronic signal into digital signals, respectively;

    information storing means for storing a temperature coefficient; and

    signal processing means for processing the first electronic signal generated by the infrared radiation sensor means and the second electronic signal generated by the temperature sensor means and compensating by using the temperature coefficient stored in the information storing means so as to calculate an amount of the infrared radiation from the target, and to obtain a target temperature according to the amount of the infrared radiation.
