Pin left → right: (DATA; VCC; GND)

Application:
Remote control switch, receiver module, motorcycle, car anti-theft products, home security products, electric doors, shutter doors, windows, remote control socket, remote LED, remote stereo, remote control electric doors, garage door remote control, remote control retractable doors, remote control gate volume, pan doors, remote control door opener, the door closing machine control system, remote control curtains, alarm host, alarm, remote control motorcycle, electric remote control cars, remote control MP3.

Note: 
VCC voltage to be consistent with the module operating voltage, and power to do the filtering;
Impact on the reception antenna module is large, then the best 1/4 wavelength antenna, generally use 50 ohm single wire antenna length of about 17cm 433M;
Also affect the position of the antenna reception module, install the antenna stretched as far as possible away from the shield, high pressure, and local sources of interference; receiving frequency when used, decoding and vibration resistance should be matched with the launch.
