	In experiments with electronic devices and circuit boards, the temperature of circuit components is an important indicator, and excessive temperatures may affect the performance of the circuit or even damage the circuit components. Therefore, monitoring the temperature of circuit components is quite essential to ensure the stable operation of device and extend the lifespan of circuit components.		In experiments with electronic devices and circuit boards, the temperature of circuit components is an important indicator, and excessive temperatures may affect the performance of the circuit or even damage the circuit components. Therefore, monitoring the temperature of circuit components is quite essential to ensure the stable operation of device and extend the lifespan of circuit components.

	One simple and direct way to detect whether a circuit component is abnormally hot is to touch it directly with hands. However, if the temperature is too high, such as above ~~70°C~~, direct hand contact for a few seconds can result in burns. Hence, we aim to design and fabricate a temperature detection device based on an infrared temperature sensor to ensure the safety of operators.

	Compared to traditional temperature detection methods, this infrared thermometer does not require direct contact with the object, thereby avoiding any impact on the object being measured. This feature makes it suitable for a wide range of applications in industrial and medical fields.

	Where 70 ℃ represents the approximate temperature when the circuit element is short-circuited, 37 ℃ represents the temperature of the human body, and 25 ℃ represents the room temperature (as reference). From the area of the theoretical calculation of the radiance curve, we can know the approximate order of magnitude of the blackbody radiation that can be received by Thermopile.
