In the field of modern technology, sensors are important tools for information acquisition, with a wide variety of types and diverse functions. Among them, infrared thermopile sensors have been widely used in many fields due to their unique non-contact measurement, high precision, and fast response characteristics. This article will delve into the working principle, advantages, and specific applications of infrared thermopile sensors in different fields, in order to provide readers with a comprehensive technological perspective.

Working principle and advantages

The working principle of infrared thermopile sensors is based on the thermoelectric effect, which means that when two conductors of different materials are connected together and heated, a potential difference will be generated at the contact surface, resulting in current. Infrared thermopile sensors detect the infrared radiation emitted by objects, convert it into electrical signals, and achieve non-contact temperature measurement.

The advantages of infrared thermopile sensors are mainly reflected in the following aspects: firstly, non-contact measurement, which avoids the errors and damages that may be caused by traditional contact measurement; The second is high precision, which can accurately reflect the true temperature of the object; The third is fast response, which can capture temperature changes in real time; Fourthly, it has broad applicability and can be used to measure the temperature of objects of various shapes and sizes.
