Infrared sensor is a sensor capable of detecting and measuring infrared radiation, with a number of significant features:
Non-contact: Infrared sensors can sense and measure the temperature of an object by detecting and measuring infrared radiation without having to make contact with the object. This non-contact detection method will not affect or damage the measured object during the measurement process.
Remote sensing: Infrared sensors have the characteristics of detecting a long distance, and can sense and measure distant objects, especially in the indoor environment, can sense the temperature of objects farther away.
High temperature measurement: Infrared sensors can measure high temperatures, especially in industrial control and monitoring, can measure the temperature of high temperature objects.
Fast response: The infrared sensor has the ability to respond quickly and can complete temperature measurement in a short time.
No light source: Infrared sensors do not need a light source to work, can work in low light or no light environment.
Security: Infrared sensors can be used in security-demanding scenarios, such as medical and industrial controls, because they do not cause harm to the human body or other living things.
Multi-wavelength measurement: Infrared sensors can measure infrared radiation at different wavelengths, so temperature measurement and temperature analysis can be performed at multiple wavelengths.
Energy saving: Some infrared sensors use advanced integrated circuit technology, which makes their power consumption very low, and the annual power consumption is only 2 to 3 degrees.
Strong environmental adaptability: the infrared sensor is not sensitive to environmental interference, and the thermal radiation signal will not be affected by environmental factors such as light and haze, so it has good stability and reliability.
In addition, the infrared sensor has some other features, such as the ability to operate in an environment without oxygen, the need for frequent calibration, and the use of human infrared sensing principles to achieve automated light control. These characteristics make infrared sensors widely used in security monitoring, smart home, industrial automation and other fields.
Please note that although infrared sensors have many advantages, there are some limitations, such as possible errors due to factors such as weather, gases, and relatively high prices. When selecting and using infrared sensors, it is necessary to weigh and consider them according to specific application scenarios and needs.
