1 CHANNEL 433MHZ RF 12V RELAY
1-channel 433MHz RF 12V relay module for remote control of AC/DC devices with Arduino, Raspberry Pi, and microcontrollers.
The 1-Channel 433MHz RF 12V Relay Module is a wireless relay solution that allows you to control AC or DC devices remotely using a 433MHz RF transmitter. Operating at 12V control voltage, it can safely switch loads such as lights, fans, motors, and home appliances.
This module is ideal for home automation, remote-controlled electronics, DIY IoT projects, and wireless switching applications. It features indicator LEDs for relay status, a secure relay output via screw terminals, and reliable RF signal reception. Compatible with Arduino, Raspberry Pi, and other microcontrollers, it enables easy integration into wireless control systems.
