433MHz 12V Wireless Remote Control Switch Module and RF Remote Control (5 pieces)

Very practical to use, simple wiring diagram.

Supports remote control of up to 19 devices. Can be connected to electric locks, lights, electric curtains, etc. It can remotely unlock, turn off lights, open and close curtains, etc.

Ultra-small body, takes up less space. The receiver board size is only about 3.5*3*3cm.

The operating mode can be changed manually: it can be switched to instant mode, switch mode, and lock mode as needed.

Code-to-code learning: it can be used with any remote control of the same frequency, so you don't have to worry about losing the remote again. (If the remote is lost, you can buy a pair with the PCB.)
