The rapid development of smart homes greatly facilitates people's lives, and the use of remote controls brings a different experience to life. People can use remote controls to shorten their working distance. Remote controls are now widely used in television, air conditioning, electric fans, and other equipment control. With the development of electronic technology and the increasing demand of society, the integration, intelligence, and environmental protection of related equipment have gradually become the mainstream.
The most common remote controls in our daily lives are infrared remote controls and wireless remote controls. These two remote controls are quite common in daily life. Next, let's introduce what infrared remote controls are and what wireless remote controls are.
The infrared remote control utilizes wavelengths ranging from 0.76 to 1.5 μ A remote control device that transmits control signals through near-infrared radiation between m. The characteristic of infrared remote control is that it does not affect the surrounding environment or interfere with other electrical equipment. Due to its inability to penetrate walls, household appliances in different rooms can use a universal remote control without mutual interference; Circuit debugging is simple, as long as the given circuit connection is correct, it can generally be put into operation without any debugging; Easy encoding and decoding, capable of multiple remote control. Therefore, infrared remote control has been widely used in household appliances and indoor close range (less than 10 meters) remote control.
A radio remote control device is a remote control device that uses radio signals to control various remote mechanisms. After these signals are received by remote receiving devices, they can command or drive other corresponding mechanical or electronic devices to complete various operations, such as closing circuits, moving handles, starting motors, and then these machines can perform the necessary operations. As a type of remote control that complements infrared remote control, it has been widely used in garage doors, electric doors, road gate remote control, anti-theft alarms, industrial control, and wireless smart home fields.
