The common carrier frequency of wireless remote controller is 315MHz or 433MHz. Wireless remote controller is a device used to remotely control machines, which has also been widely used in life. The wireless remote controller uses the open frequency band stipulated by the state. In this frequency band, if the transmission power is less than 10MW, the coverage is less than 100m or does not exceed the scope of the unit, it can be used freely without the approval of the "Radio Regulatory Commission". China"s open frequency band is 315MHz, while Europe and the United States and other countries stipulate 433MHz. Therefore, 433MHz remote controller shall be used for products exported to the above countries. It is a device used to remotely control the machine.

Modern wireless remote controls are mainly composed of integrated circuit boards and buttons used to generate different messages. Up to now, wireless remote controls have been more and more used in life and brought great convenience to people. With the progress of science and technology, wireless remote controls have also expanded to many kinds It has four buttons: deploy / disarm / deploy at home / emergency. The alarm host can be remotely controlled or used as an emergency button. The wireless remote controller adopts SMT imported patch elements, with push-button cover protection device. The metal shell is small and beautiful. Its transmitting end is generally of two types: one is the complete remote-control transmitter and the other is the remote-control transmitter module. The transmitter and the remote control transmitter module are based on the difference in use. The transmitter can be used independently, and the receiving end can lead out the wiring terminal; The remote control module is usually used as a component part, which is defined according to the actual demand. The module can be seamlessly connected with the existing line, which is small and cheap.
