Types of infrared sensors
Infrared sensors are devices that can detect and measure infrared radiation. They are widely used in security, automatic control, medical, communication, and aerospace. According to different working principles and applications, infrared sensors can be divided into the following types: Thermonuclear sensor: uses the thermonuclear effect to convert thermal energy into a voltage signal, and measures the temperature change of the infrared radiation object to achieve temperature detection and measurement. Thermonuclear sensor: uses the change in resistance value to measure temperature. The temperature change of infrared radiation affects the resistance value of the conductor. By measuring the change in resistance value, the temperature of the infrared radiation object can be obtained. Thermal conductivity sensor: uses the change in the thermal conductivity of the material to measure the concentration of the gas. When infrared radiation passes through the gas, it will caus...
