Arduino project for receiving and (in the future) transmitting signals using a 433 MHz RF module. Currently, this repository contains code for a 433 MHz signal receiver, which allows reading signals ...

// Receives messages from a 433 MHz ASK receiver using the RadioHead RH_ASK driver on Arduino (RX on digital pin 11) and prints received text to the serial console ...

This cost-effective 433MHz wireless relay switch circuit allows remote relay control using an RF transmitter and receiver module. It is ideal for scenarios where wired connections are impractical or ...

The 433 MHz RF Signal Strength Detector is a circuit designed to sense and measure the intensity of radio frequency signals in the 433 MHz ISM band. This band is commonly used by devices such as ...

Abstract: This paper presents a wireless communication system utilizing a 433MHz RF module alongside human presence detection using a Passive Infrared (PIR) sensor. The system is designed to enable ...
