This creation is a kind of ear thermometer, comprising: a gun body, a circuit board, an isotherm formula infrared sensing unit and a luminescence unit. Gun body one end has a probe. Circuit board is arranged in gun body. Isotherm formula infrared sensing unit, setting what pop one's head in interior and are electrically connected circuit board. In its setting what of luminescence unit is popped one's head in and it is electrically connected circuit board. Thereby, this creation be combined with each other through isotherm formula infrared sensing unit with luminescence unit, operator is allowed to measure ear temperature Hou, the body temperature of testee is directly judged by the color of probe sending, solve the problems, such as that general ear thermometer what is dim or night-environment in be not easy to recognize measuring value, and then obtain the convenience of temperature information. This wound separately provides a kind of temperature sensing mould group being arranged in what ear thermometer.本創作為一種耳溫槍，包括：一槍體、一電路板、一等溫式紅外線感測單元及一發光單元。槍體一端具有一探頭。電路板設置在槍體內。等溫式紅外線感測單元，其設置於探頭內且電性連接電路板。發光單元其設置於探頭內且電性連接電路板。藉此，本創作透過等溫式紅外線感測單元與發光單元相互結合，讓操作者量測耳溫後，直接藉由探頭發出的顏色來判斷受測者的體溫狀態，解決一般耳溫槍於昏暗或夜間環境中不易辨識量測值的問題，進而獲得溫度資訊的便利性。本創另提供一種設置於耳溫槍內的溫度感測模組。
