5V DC 1-Channel Infrared IR Wireless Relay Module

Quick Introduction: Cut the cord and add wireless control to your projects effortlessly. The DC 5V 1-Channel IR Relay Module is a standalone remote switching solution that requires no programming or microcontrollers. Simply power the module with 5V, connect your load (like a lamp or lock) to the relay, and use the included infrared remote to toggle it ON and OFF. It’s the simplest way to add "Smart Home" features to "Dumb" appliances.

Quality Advantage & Differentiation Why choose this IR Relay Kit?

1. Zero Coding Required: Unlike Arduino or ESP32 modules that need complex code to decode IR signals, this board has a pre-programmed MCU. It works straight out of the box.

2. High-Current Relay: Equipped with a genuine Songle (or equivalent) relay capable of handling mains voltage (250VAC), making it suitable for household lamps and fans, not just small DC motors.

3. Stability: The circuit includes a freewheeling diode to protect against voltage spikes and a transistor driver to ensure reliable relay switching without overloading the logic chip.

Key Applications & Usage

• Lighting Control: Install it in a lamp fixture to turn it on/off from bed.

• Projector Screens: Automate the raising and lowering mechanism of a motorized screen.

• Electronic Door Locks: Use it as a trigger for a solenoid lock (ensure 5V power is stable).

• DIY Robotics: Remotely activate specific functions or power up a robot chassis.

What's Included & Required

• Included: 1x 1-Channel 5V Relay Module, 1x Infrared Remote Control.

• Required: 5V DC Power Source (USB or Battery), Wires for load connection.

The "Virtual Technician" Support Panel

• ⚠️ THE "DRY CONTACT" RELAY:

  • Important: The output terminals (NO, COM, NC) are switches, not power outlets. They do not output voltage.

  • How to Wire: You must connect the "Live" wire of your appliance to COM and the NO terminal to the appliance. The circuit acts as a bridge. If you just connect a motor to NO/COM without a battery in the loop, nothing will happen.

• ⚠️ IR LINE OF SIGHT:

  • This uses Infrared light (like a TV remote). The black LED sensor on the board must be able to "see" the remote. It will not work through opaque walls or inside metal boxes.

• ⚠️ INTERFERENCE:

  • Strong sunlight or fluorescent tube lighting can sometimes flood the IR sensor, reducing range or causing erratic switching. Keep the sensor shaded for best results.
