reed switch relay Electronics-Base.comThe reed switch is an electrical switch operated by an applied magnetic field. It consists of a pair of contacts on ferrous metal reeds in a hermetically sealed glass envelope. They are often used in alarm systems, on bicycles for wheel speed measurement and in many other devices. Here we will say few words about reed switch and show you very interesting video how they are made

logoIt is well known that many gas molecules can absorb radiation in the infrared portion of the electromagnetic spectrum. When infrared radiation is incident on the gas, the energy states of atoms vibrating in the molecules change in discrete steps when the wavelength of the infrared matches the molecules natural frequencies or resonances. Put simply, the vibrations of atoms held in their chemical bonds increase when excited by light of the right wavelength.

color-sensor-devicesLight .Visible light is an electromagnetic wave in range of 400 to 700nm. This is just a small part of all existing wavelengths. The light that we see is not one wavelength but a combination of many wavelengths.
The spectral power distribution - SPD shows the precise dependence of the color in function of light source in the form of diagram that represents energy at each wavelength in the visible spectrum.
