The garage(garage door remote） is mainly divided into remote control, induction, electric and manual, and the garage door remote is the device to remotely control the opening and closing of the garage door. Generally speaking, the garage door remote usually adopts the radio remote controller in the remote controller rather than the infrared remote controller, because compared with the infrared remote controller commonly used in household appliances, the radio remote controller has the following advantages. The radio remote controller uses radio waves to transmit control signals. Its characteristics are non directionality, no "face-to-face" control and long distance (up to tens of meters, or even several kilometers) and vulnerable to electromagnetic interference. It is easy to use the radio remote controller in the fields requiring long-distance penetration or non directional control, such as garage door remote control, industrial control, etc.
