Classification of remote control
In this era of technology, intelligent products are everywhere. In today's technology era, there are many things that can be remotely controlled by remote control. The remote controller has been widely used in the control of TV, air conditioner, electric fan and other equipment. With the development of electronic technology and the increase of social demand, the integration, intelligence and environmental protection of relevant equipment have gradually become the mainstream.

Infrared remote control and wireless remote control are the most common remote controls in our lives. These two remote controls are very common in life. Next, let's introduce what is an infrared remote control and what is a wireless remote control. What is the difference between the two?
The infrared remote control uses a wavelength of 0. 76 ～ 1.5 μ M Remote control equipment transmits control signals through near-infrared ray. The feature of infrared remote control is that it does not affect the surrounding environment and does not interfere with other electrical equipment. Because it cannot penetrate the wall, household appliances in different rooms can use universal remote control, which will interfere with each other; As long as the given circuit is connected correctly, it can be put into use without any debugging; Coding and decoding are very easy, and multiple remote control can be carried out. Therefore, infrared remote control is widely used in household appliances and indoor short-range (less than 10 meters) remote control.

The radio remote controller is a remote control device, which uses radio signals to control equipment. After receiving these signals, the remote receiving equipment can command or drive other corresponding mechanical or electronic equipment to complete various operations, such as closing the circuit, moving the handle, starting the motor, and then these machines can perform the required operations. As a supplementary type of infrared remote control, it is widely used in garage door, electric door, road door remote control, anti-theft alarm, industrial control and wireless smart home.
The difference between radio remote control and infrared remote control: infrared remote control and wireless remote control are different carriers, and infrared remote control is an infrared transmission control signal, which is characterized by directionality and can not be blocked. The distance is generally not more than 7 meters, and is not subject to electromagnetic interference. TV remote control is an infrared remote control; The radio remote control is a radio wave transmission control signal, which is characterized by non-directionality, can not be "face to face" control, long distance (up to tens of meters or even several kilometers), and is vulnerable to electromagnetic interference. It is easier to use radio remote control to solve the fields that need remote penetration or directionless control, such as industrial control.
That's why I want to share with you some differences between common remote controls in life
