What Are the Different Types of IR Remotes?

Remote control technology, also known as remote control technology, refers to the realization of remote control of controlled targets. It is widely used in the fields of industrial control, aerospace and home appliances.

Infrared is also called infrared light wave. In the electromagnetic spectrum, the wavelength range of the light wave is 0.01um ~ 1000um. It can be divided into visible light and invisible light according to different wavelengths. Light waves with a wavelength of 0.38um ~ 0.76um can be visible light, which are seven colors in order: red, orange, yellow, green, cyan, blue and purple. Light waves with a wavelength of 0.01um to 0.38um are ultraviolet light (line), and light waves with a wavelength of 0.76um to 1000um are infrared light (line). Infrared light is divided into near infrared, mid infrared, far infrared and extreme infrared according to the wavelength range. Infrared remote control is used

The transmitting circuit of the infrared remote control is using

Since the infrared remote control does not have the ability to control the controlled object through obstacles like the radio remote control, when designing the infrared remote control of household appliances, it is not necessary to set each (transmitter and receiver) like the radio remote control. Must have different remote control frequencies or codes (otherwise, it will control or interfere with neighbors home appliances across the wall), so the infrared remote control of similar products can have the same remote control frequency or code without the remote control signal" string door " Case. This provides great convenience for mass production and popularization of infrared remote control on home appliances. Infrared is invisible light, so it has little impact on the environment. In addition, the wavelength of infrared light fluctuations is far less than the wavelength of radio waves. Therefore, infrared remote control will not affect other household appliances, nor will it affect nearby radio equipment.
