You need the following components for this example:

The other Arduino board will be connected to a 433 MHz receiver to receive the messages. An Arduino board will be connected to a 433 MHz transmitter and will send the “Hello World!” message. In this section, we’ll build a simple example that sends a message from an Arduino to another Arduino board using 433 MHz. Arduino with RF 433MHz Transmitter/Receiver Modules Click here to compare the RF 433MHz transmitter/receiver on several stores and find the best price. You can purchase these modules for just a few dollars. These modules are very cheap and you can use them with any microcontroller, whether it’s an Arduino, ESP8266, or ESP32. These RF modules are very popular among the Arduino tinkerers and are used on a wide variety of applications that require wireless control. Throughout this tutorial we’ll be using the FS1000A transmitter and corresponding receiver, but the instructions provided also work with other 433MHz transmitter/receiver modules that work in a similar fashion. Decode and Send 433 MHz RF Signals with Arduino.

We have other tutorials about the 433MHz transmitter/receiver that you may found useful: We’ll explain how they work and share an Arduino project example that you can apply to use in your own projects.

This post is a guide for the popular RF 433MHz Transmitter/Receiver modules with Arduino.
