Test report of Infrared emitting and receiving

Test report of Infrared emitting and receiving
First:The principle of infrared, infrared remote control has been widely used in home appliances and industrial control system,
need realize one important thing that work principle and performance, also is not difficult.

*Characteristic of  infrared :eye can see the visible light wavelength,
arranging wavelength in color sequence;  red, orange, yellow, green, cyan, blue, purple, respectively The red light in the wavelength range as 0.62μm ~ 0.76μm, more longer than the red wavelength light is infrared. The infrared ray To exhibit similarity with ir led strips.

*Application: Infrared remote control is the use of 0.76μ m～1.5μ m  wavelength(near infrared)to transmit a control signal. feature of Infrared is that it does not interfere with other electrical equipment work, it will not affect the surrounding environment. Circuit is simple,
coding for transmitted signal can realize the function of multi-channel infrared remote control.Secode: divide the infrared remote control system into receive model and emitting model. The emission component parts as infrared emitting diode, the emits infrared as visible light, Common infrared infrared wavelengths emitted from the light emitting diode is about 940nm,the shape is the same with φ 5 mm light emitting diode, but different colours. In general there are transparent, black and dark blue three type.

What kind of relationship infrared with the human body?

What kind of relationship infrared with wavelengths of  human body ?The human body （like a ir led strips in operation）have  generated vast amounts of  far infrared in every moment。it was determined: far-infrared wavelengths near 9.6 micron emission in the human body! Wavelengths (5.6-15 microns) and far infrared wavelength emitted from the human body (the average temperature is 36.5 ℃, the temperature  translated into the wavelength as 9.4 microns) overlap,   in the same band range of frequency, it is possible to make cell of human body  in active mode, a phenomenon called resonance!It can activate cells, promote blood circulation, accelerate metabolism, enhance that the body's own immune function! theResonance is laws of nature, Called resonance in mechanics,  Called  chord  in Acoustics,called harmonic in electronics 。Resonance can make the energy feedback effect is greatly improved. , greatly increase the range of motion of the original object! Can see this phenomenon through the experiment in vivo! From the microscopic point of view, due to the movement of human biological cell, including a large number of water molecules motion (vibration, rotation suchetc...) will cause internal transitions particles! When the transition from a high energy level to a lower energy level, with  a light energy to radiation of infrared light. This is far-infrared light-emitting mechanism! This movement is a normal physiological activity,   Conversely,when the far infrared emission wavelength close to the body of human, because the frequency is close to resonance (or the resonant), which can make human body cell and molecular motion( increasing physical activity)
.which is obviously to activate cells,  really boost metabolism!
the warm effect of human body is closely related with far infrared ray. By irradiating, the cell and moleculeswas involved in a collision and  enormous increase in human body., this will make the thermal effect is more obvious, more in-depth(to be able to penetrate the human skin approximately 4-5 cm)! In addition, because the human body continuously emit far infrared rays, in this frequency range, but also to the direct absorption of far infrared band to supply pelople's bodies with Energy! We can say that The human body （like a ir led strip in operation）have  generated vast amounts of  far infrared in every moment, but also  absorption in the far infrared in every moment, at the same time, , human life is inseparable from the far infrared ray from the origin to the development! this Why it is so important for every one.
