In this age of technology, smart products are everywhere. In today's technological era, there are many things in life that can be remotely controlled with remote controls. Remote controls are now widely used in TVs, air conditioners, 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.
At present, the common remote controls in our lives are: infrared remote control and wireless remote control. These two remote controls are more common in life. Next, I will introduce what is an infrared remote control and what is a wireless remote control. What is the difference between the two?
Infrared remote control is a remote control device that transmits control signals using near-infrared rays with wavelengths between 0.76 and 1.5 μm. The characteristic 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 a universal remote control without mutual interference; circuit debugging is simple, as long as the given circuit is connected correctly, generally it can be put into work without any debugging; codec Easy, multi-channel remote control is possible. Therefore, infrared remote control has been widely used in household appliances and indoor short-range (less than 10 meters) remote control.
A radio remote control is a remote control device that uses radio signals to control various institutions in the distance. After these signals are received by the remote receiving device, they can instruct or drive various other corresponding mechanical or electronic devices to complete various operations, such as closing the circuit, moving the handle, and starting the motor, and then these machines will perform the required operations. As a kind of remote control that complements the infrared remote control, it has been widely used in the remote control of garage doors, electric doors, gates, burglar alarms, industrial control and wireless smart homes.
The difference between radio remote control and infrared remote control: infrared remote control and wireless remote control are for different carriers, and infrared remote control uses infrared to transmit control signals. No more than 7 meters, no electromagnetic interference, the TV remote control is an infrared remote control; the radio remote control uses radio waves to transmit control signals. up to tens of meters, or even kilometers), susceptible to electromagnetic interference. In the fields that require long-distance penetration or non-directional control, such as industrial control, etc., it is easier to use a radio remote control.
The above is what I share with you about the common remote control classifications in life and some of the differences between them
