I believe infrared detectors measure heat being given off by an object. However since everything gives off heat.. the detectors have to be cooled down to very low temperatures themselves using liquid helium croyogen. Emma D
Infrared detectors are commonly used to detect wavelengths in the infrared range of the electromagnetic spectrum. They can be made using various technologies, such as thermopiles, pyroelectric detectors, and semiconductor-based detectors like InSb or HgCdTe detectors. These detectors convert infrared radiation into an electrical signal that can be analyzed or used for various applications.
Yes. Infrared are currently considered to be the best option to detect gas leaks. They use the absorption of infrared radiation at certain wavelengths to detect dangerous levels of toxic and combustible gases.
Humans cannot naturally detect infrared waves, as they are beyond the visible light spectrum. However, infrared detectors and sensors can be used to detect infrared waves. These devices work by converting infrared radiation into an electrical signal that can be interpreted by humans. Common methods for detecting infrared waves include thermal imaging cameras, infrared thermometers, and infrared sensors.
Infrared detectors are used in various applications including security systems for motion detection, temperature measuring devices, night vision cameras, and industrial processes for detecting heat signatures and anomalies in machinery. They are also used in medical imaging for detecting skin temperature variations and detecting tumors in thermography.
Yes, heat can affect PIR (passive infrared) detectors by potentially causing false alarms or reducing their sensitivity. Extreme temperature changes or direct exposure to heat sources can impact the accuracy of these detectors. It is essential to install PIR detectors away from direct sunlight or heat sources to ensure optimal performance.
Motion detectors are: infrared detectors, ultrasonic, microwave, radiowave and... dogs.

An infrared detector needs a power source to operate and it is used to active a relay that can be used as a switch.
Antimony is used in flame retardants, lead-acid batteries, and as a component in semiconductor materials such as infrared detectors. It is also used in the production of certain types of glass and ceramics, as well as in the manufacturing of pigments and catalysts.
Photo-electric (PE - as opposed to the ionization type of) smoke detectors do indeed use the reduction of light energy at the receiving end to "Sound The Alarm". Whether or not this is IR energy, I can't say. Might someone else please fill this in? Thanks.
The chemical compound thallium bromide (TlBr) is used in real time X-ray image sensors, room temperature X-ray and gamma ray detectors and blue sensitive photo-detectors. It is also used as a standard for elemental thallium.
Interior systems usually provide infrared motion detectors located in strategic areas
