Classification of Remote Control
At present, the most common remote controls in our lives are: infrared remote control and wireless remote control. These two remote controls are more common in life. Next, let me introduce to you 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 uses near-infrared rays with a wavelength between 0.76 and 1.5 μ m to transmit control signals. 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; the 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 can be carried out. Therefore, infrared remote control
