nframerah is electromagnetic radiation of a wavelength longer than visible light, but shorter than radio waves radiation. His name means "below red" (from the Latin infra, "below"), red is the color of visible light with the longest waves. Infrared radiation has a range of three "orders" and has a wavelength between 700 nm and 1 mm. Infrared discovered by accident by Sir William Herschell, English astronomer royal when she was conducting research for optical filter material that will be used to reduce the brightness of the image of the sun in the solar telescope.


* Can not be seen by humans
* Can not penetrate the material that is not transparent
* Can be generated by heat generating components
* The infrared wavelength has the opposite relation or inversely proportional to the temperature. As the temperature increases, so wavelength decreases.

The types of infrared wavelengths based

* Infrared distance close to the wavelength of 0.75 - 1.5 ?m
* Infrared medium range with a wavelength of 1.50 - 10 ?m
* Infrared remote with wavelengths from 10 to 100 ?m

Infrared excess in the data transmission

* Shipping with infrared data can be done anytime, for delivery via infrared signal does not need.
* Shipping with infrared data can easily be said for including a simple tool.
* Delivery of data from the phone is not a cost (free)

Weakness in infrared data transmission

* In the data transmission via infrared, infrared second hole should be facing each other. It is rather difficult for us to transfer data because of the way of trouble.
* Infrared is very dangerous for the eyes, so do not even infra-red beam on the eye
* Delivery of data via infrared can be said more slowly than his Bluetooth.

[edit] Field spatial

Dipancarakan infrared in the form of infrared rays to an object, can produce infrared images. Photo infrared radiant heat works on an object can be used to create a painting from a local heat or object. Hot picture results can illustrate which areas are hot and not. A hot picture of a building can be used to determine which part of the zone of the building that produce heat that can be done berlebihann improvements are needed.
[edit] Industry Sector

* Infrared light. An incandescent lamp of wire pijarnya ± temperature above 2500 ° K. this causes the infrared light it emits becomes much more than incandescent lamps can. Infrared lamps are commonly used to perform the heating process in the industry.
* Warm-infrared. It is a condition when the infrared energy to attack an object with the power emitted electromagnetic energy above -273 ° C (0 ° K in absolute temperature). Infrared heating is widely used in such tools, grill lights danbola (90% heat - 10% light)
