Overview

Product Overview

433MHz 12V 1-channel relay module for wireless remote switching, designed to turn compatible 12V devices on or off from a distance using the included battery-powered remote control. This wireless relay receiver is ideal for home automation, garage doors, access control, lighting, alarms, and general remote power switching where simple 433MHz RF operation is preferred over WiFi or Bluetooth. A practical 433MHz RF relay board for DIY electronics, vehicles, enclosures, and retrofit projects, it provides convenient single-channel control for 12V loads in standalone automation setups that need dependable remote switching without a wired trigger, app, or internet connection.

Questions & answers

Frequently asked questions

It does not require an Arduino or Raspberry Pi; it works as a standalone 12V RF relay receiver controlled by the included remote. You can use it alongside controllers if switching a compatible load, but no code, app, WiFi, or Bluetooth is needed.
It is designed for standalone remote switching with the included battery-powered remote, so no app, internet connection, wired trigger, or programming is required. You still need to wire a suitable 12V power supply and compatible load correctly.
The receiver is a 12V, single-channel relay module and communicates over 433MHz RF with the included remote. The listing does not specify relay contact ratings, so confirm your device's voltage and current requirements before connecting a load.
This module fits simple on/off control for home automation, garage doors, access control, lighting, alarms, vehicles, enclosures, and retrofit projects. It is useful when RF remote control is preferred over WiFi, Bluetooth, an app, or internet service.
The supplied battery-powered remote is intended for this receiver; compatibility with other 433MHz remotes is not guaranteed from the provided information. For replacements or extra remotes, match the receiver's required coding and protocol before buying.
