Description

Technical Field

[0002] Wireless infrared intrusion detectors are devices that convert incident infrared radiation signals into electrical signal outputs. Infrared radiation is an electromagnetic wave with a wavelength between visible light and microwaves, which is imperceptible to the human eye. To detect the existence of this radiation and measure its strength, it must be converted into other physical quantities that can be detected and measured. Generally speaking, any effect caused by infrared radiation irradiating an object can be used to measure the strength of infrared radiation as long as the effect can be measured and is sensitive enough. Modern infrared detectors mainly use infrared thermal effects and photoelectric effects. The outputs of these effects are mostly electrical quantities, or can be converted into electrical quantities by appropriate methods. An infrared detector has at least one object that is sensitive to infrared radiation, called a response element. In addition, it also includes a bracket, a sealed housing, and a window that transmits infrared radiation for the response element, and sometimes also includes refrigeration components, optical components, and electronic components.
