RF433 mhz
A 433 MHz wireless remote is a device that uses radio frequency signals at a frequency of 433 megahertz to wirelessly control or communicate with other devices. These remotes are commonly used for various applications such as home automation, garage door openers, car alarms, and other remote control systems.
A relay module paired with a 433 MHz wireless remote is often used in home automation and electronics projects. The 433 MHz remote can send signals to the relay module, which, in turn, controls the switching of electrical circuits. This setup is useful for tasks like turning lights on/off, opening/closing doors, or activating other devices wirelessly.
The wiring for a relay module in conjunction with a 433 MHz wireless remote typically involves connecting the relay module to both a power source and the device you want to control. Here's a basic guide:
Power Supply:
Connect the VCC (or +) and GND (or -) pins on the relay module to a suitable power source (e.g., 5V power supply). Ensure the voltage matches the specifications of your relay module.
Control from 433 MHz Remote:
Connect the data or signal pin of the 433 MHz receiver on the relay module to the appropriate input on the relay module. This is usually labeled as 'Data' or 'Signal.'
Output Connections:
Connect the Common (COM) pin, Normally Open (NO) pin, and Normally Closed (NC) pin of the relay to the corresponding terminals of the device you want to control.
Load Connection:
Connect the device you want to control to the Common (COM) and either the Normally Open (NO) or Normally Closed (NC) depending on whether you want the relay to be normally open or normally closed.
Power for Controlled Device:
Provide the necessary power supply to the device connected to the relay.
