Abstract
The disclosure provides a temperature sensing device including a thermopile sensing assembly with a metal sleeve and a metal grid for blocking microwave from entering the thermopile sensor and influencing temperature detection. The temperature sensing device includes one or more than one thermopile sensing elements, an ambient temperature sensor, a signal processing chip, and an infrared lens providing narrow FOV. When dual thermopile sensing elements are used, one is active unit with narrow FOV for measuring the infrared radiation of the object to be detected, and the other one is a dummy unit for the compensation of the thermal shock to achieve the purpose of accurate temperature detection. The disclosure also provides the visible light source to indicate the sensing area of the thermopile sensor, that may facilitate the user positioning the object to be heated. FOV of the light source is the same with that of the thermopile sensor.
