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

Arduino. We’ll explain how they work and share an Arduino project example that you

can apply to use in your own projects.

Description

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. These RF modules are very popular among the Arduino

tinkerers and are used on a wide variety of applications that require wireless control.

These modules are very cheap and you can use them with any microcontroller (MCU),

whether it’s an Arduino, ESP8266, or ESP32.
