Description:

Uses: remote control switch, receiving module, motorcycle, car anti-theft products, home anti-theft products, electric door, rolling door, window, remote control socket, remote control LED, remote control audio, remote control electric door, remote control garage door, remote control door opener, and other door control systems, security and other civil and industrial supporting remote control field.
Transmitter module has three external interfaces, 1. ATAD: data input pin ; 2. VCC: power supply positive pole ; 3. GND: power supply negative pole.
The VCC voltage should be consistent with the working voltage of the module, and power filtering should be done.
The antenna has a great influence on the receiving effect of the module. It is better to connect the antenna with 1/4 wavelength. Generally, 50 ohm single conductor is adopted.
The antenna position also affects the receiving effect of the module. When installed, the antenna should be as straight as possible, away from the shielding body, high pressure and the interference source. The receiving frequency, decoding mode and oscillating resistance should be with the transmission when used.
