  • Tested

This is one channel RF Receiver with an onboard Relay. The project can be used for ON/OFF control of AC or DC loads using an RF remote. It’s an Arduino compatible Receiver project that consists of, Atmega328 microcontroller, 315MHz RF Receiver, 12v Relay, 5V Regulator, etc.

Arduino Pins Receiver: D3 Relay, D11 Data in from AM 315Mhz Receiver.

Features

  • Supply 12V DC @ 50mA When Relay is ON
  • Relay Contacts 10A @ 24V DC, 5Amps @ 250V AC
  • PCB dimensions: 64.77 x 32.86 mm

Applications

RF Remote ON/OFF Fans, Lights, Home Appliances, Door control. This receiver is compatible with 4 Channel 315Mhz RF Remote Transmitter and 2 Channel 315Mhz RF Remote Transmitter.

Arduino Code

Arduino Code provided as a download. The code is compatible with our 315Mhz Transmitter project, it toggles the Relay when the switch is pressed. A new Atmega328 chip requires Bootloader and Arduino firmware programming, check link bellow to learn more about programming the new Atmega328. PCB has an onboard programming port.
