The principle of wireless shower
Wireless demonstrators combined with wireless technology and computer USB technology to control the computer to turn pages, which is equivalent to computer remote control.Products usually include a transmitter and a receiver.The receiver is similar to a USB flash drive. When the USB port is inserted on the computer, the computer will automatically install the corresponding driver.At this time, press the button on the transmitter to achieve a wireless control computer.
Wireless technologies used in remote -control laser pens are usually infrared and radio frequency.I believe that everyone is very familiar with infrared products. The TV remote control and air -conditioning remote control we usually use are all infrared technology.RF products have no directionality. As long as there is no large -scale metal blocking between the transmitter and the receiver, it can be used normally.The cost of radio frequency products is usually higher, but it is not directed and more convenient to use.
