Tutorial: How to use 1-Channel Relay Receiver + 433 MHz Transmitter

This 1-channel DC12V relay receiver and 433 MHz transmitter are ideal for remotely controlling electrical devices. They are perfect for home automation projects or for those starting with Arduino.

What you need

• 433 MHz 1 Channel Relay Receiver
• 433 MHz Transmitter
• Arduino
• Breadboard Connectors
• Relay
• 12V Power Supply
• 433 MHz Antenna (optional)

Steps

1. Connect the transmitter to the receiver using the 433 MHz antenna (optional)
2. Connect the receiver to the relay
3. Connect the relay to the Arduino
4. Configure the Arduino to receive signals from the transmitter
5. Write the Arduino sketch to manage the relay
6. Check the electrical connection
7. Test the system by pressing the transmitter buttons
8. Verify that the relay activates correctly

Example code

void setup() {
  pinMode(relayPin, OUTPUT);
}

void loop() {
  if (digitalRead(signalPin) == HIGH) {
    digitalWrite(relayPin, HIGH);
  } else {
    digitalWrite(relayPin, LOW);
  }
}

Mini project

Create a remote control system for a small fan. Connect the relay to the fan and use the transmitter to turn the fan on and off from a distance.

Common mistakes

• Ensure that both the transmitter and receiver are at 433 MHz
• Verify that the relay is correctly connected to the Arduino
• Check that both the transmitter and receiver are powered
• Verify that the receiver is receiving signals from the transmitter

Recommended accessories

• 433 MHz Antenna
• 5V Relay
• 12V Power Supply
• Banana Plug Connections

Frequently asked questions

Do the transmitter and receiver only work at 433 MHz?
Yes, make sure both devices are set to 433 MHz.

Can I connect multiple relays to the receiver?
Yes, but you will need to add more channels or use a multiplexer.

What buttons do I have available on the transmitter?
The transmitter generally has 4 buttons to control the channels.
