Q:What is the working principle of infrared sensors?
An infrared sensor includes an optical system, a detection element, and a conversion circuit. Depending on the structure, the optical system can be divided into two types: transmission and reflection. The detecting element can be divided into heat detecting element and photoelectric detecting element according to the working principle. Thermistors are the most widely used thermistors. When the thermistor is subjected to infrared radiation, the temperature increases, the resistance changes, and the electrical circuit is converted into an electrical signal output. The photoelectric detection element is the commonly used photosensitive element, usually made of PBS, PbSe, InAs, arsenic, antimony, germanium and three HgCdTe alloy silicon doped materials.
Q:The working principle of metal detectors!
Metal detector (metal detector) is a high performance metal detector designed for security. There are three main categories: electromagnetic induction, X ray inspection, microwave detection, electronic instruments for detecting metals, and can be used in many fields.
Q:What's the distance between the smoke and the light?
Smoke sense is actually another name for smoke detectors or smoke alarms. The smoke detector is by monitoring the concentration of smoke to achieve fire prevention, smoke detectors, the internal use of ion smoke sensor, ion smoke sensor is a kind of advanced technology, stable and reliable operation of the sensor, is widely used in all kinds of fire alarm system, fire alarm performance is far better than the gas sensing resistance type.
Q:Does an earthquake detector have radiation?
Safety in the scope of metal detectorCheck gate, the old X ray is used to detect, and now also through the electromagnetic field to detect metal objects. But the railway station, bus station and airport are rightLuggage inspection is generally X ray, but its inspection is hidden in the door curtain, even if the staff next to it will not be affected, the overall frequency of the human body orSafe。
Q:What is the principle of an infrared detector?
According to the mode of energy conversion, infrared detectors can be divided into two categories: thermal detectors and photon detectorsThe working mechanism of thermal detector is based on the thermal effect of incident radiation caused by the change of electrical characteristics of a detector, and the photon detector is the photoelectric effect and incident photon flux detection materials based on the interaction, the specific performance of the detector response element free carrier (i.e., electronic and / or change the number of holes). Because of this change is caused by by the change of the incident photon, photon detector response is proportional to the photon absorption. The thermal detector response is proportional with the absorbed energy.
Q:Advantages and disadvantages of infrared detectors
Advantage:The device does not send any type of radiation, so the power consumption of the device is very small, and the concealment is better.Low price
Q:What specific applications does UV detectors have in military (military) applications?
Ultraviolet light is absorbed when entering the atmosphere, while infrared light passes through the atmosphere, so the infrared interference in the atmosphere is more serious, while the ultraviolet environment is relatively clean. So UV detector can detect heat source in strong infrared interference environment.
Q:Imaging characteristics of thermal detectors
When working, the thermal imager optical device using infrared energy is focused in the scene from objects in infrared detectors, infrared data from each detector element and then converted into a standard video format that can be displayed in the standard video monitor, or recorded on videotape. Since the thermal imaging system detects heat rather than light, it can be used all day long; it is not entirely exposed to light or radio frequency energy because it is completely passive, so it does not expose the user's position.
Q:How to prevent mobile phones from being detected by metal detectors?
There are two detectors, one is the signal detector, the other is a metal detector. I think your school uses a signal detector, because metal detectors ring whenever they have metal, such as iron belt buckles. If it's a signal detector, you don't want your cell phone to send out a signal. Shut down, absolutely can not find out. My school is using the signal, I did not find out the shutdown.
Q:How to prevent mobile phones from being searched by detecting instruments?
There are two detectors, one is the signal detector, the other is a metal detector. Signal detectors are usually used because metal detectors ring whenever there is metal, such as iron belt buckles. If the signal detector, as long as the phone does not send a signal on it. You can't detect it when you power off.
