Infrared (IR) Remote Control Kit (Remote + Receiver)
₵20.00
This IR Remote Control Kit is the fastest and easiest way to add wireless remote control to your project. It’s the same technology used by your TV remote, and it’s perfect for controlling robots, switching relays, playing media, or triggering any function on your microcontroller from across the room.
The kit comes with two parts:
- The IR Remote: A slim, handheld remote control with buttons (often 17 or 21) that sends out a unique, invisible infrared light signal when a button is pressed.
- The IR Receiver Module (KY-022): A small 3-pin breakout board that “sees” the infrared signal from the remote. It decodes the signal and sends a clean digital pulse to your microcontroller.
This system works by sending pulses of IR light at a specific frequency (almost always 38kHz). Each button on the remote sends a different code, allowing your Arduino or ESP32 to know exactly which button was pressed.
Available on backorder
Key Features
- Complete Kit: Includes both the handheld remote and the 3-pin receiver module.
- Simple Interface: The receiver module connects to your microcontroller using just one digital pin.
- Standard Protocol: Most kits use the common NEC protocol, which is supported by excellent Arduino libraries.
- Great Range: Works up to 8 meters away (depending on lighting conditions and battery).
