Wireless infrared probe alarm anti-theft alarm YET601,use the temperature changes of the human body's infrared radiation to detect thieves.
In the field of electronic anti-theft and human body detectors, passive thermoluminescent infrared detectors are widely used, and they are welcomed by users and professionals because of their low price and stable technical performance.
Working Principle and Characteristics of Passive Thermoelectric Infrared Probe:
The human body has a constant body temperature, usually at 37 degrees, so it emits infrared rays of about 10 UM at a specific wavelength. The passive infrared probe works by detecting infrared rays of about 10 UM emitted by the human body. The infrared rays emitted by the human body are enhanced by the Fresnel filter and gathered on the infrared sensing source. Infrared sensing sources usually use thermoluminescent elements. When they receive changes in the temperature of the human body’s infrared radiation, they lose their charge balance and release charges outwards. Subsequent circuits can produce alarm signals after detection.

This kind of probe is aimed at detecting the radiation of the human body. Therefore, thermoluminescent elements must be very sensitive to infrared radiation with a wavelength of about 10 UM.
In order to be sensitive only to the infrared radiation of the human body, its radiation surface is usually covered with a special Fresnel filter, so that the interference of the environment is clearly controlled.
A passive infrared probe has two thermoluminescent elements in series or in parallel. Moreover, the two polarization directions are exactly the opposite, and the environmental background radiation has almost the same effect on the two thermal release elements, causing them to produce an electrical release effect that offsets each other, so the detector has no signal output.
Once a person invades the detection area, the human body’s infrared radiation is focused through part of the mirror and is received by the thermolysis element. However, the heat received by the two thermolysis elements is different, and the thermolysis is different. It can not be offset. After signal processing and alarm.
According to the performance requirements, the fresnel filter has different focal lengths(induction distances), resulting in different monitoring fields. The more the field of view, the tighter the control.
