Product Description The Infrared IR Wireless Remote Control Module Kit is a complete solution for adding wireless control to your microcontroller projects. The kit includes an ultra-thin 21-button infrared remote and a dedicated 38KHz IR receiver module with a pre-soldered header. It works by sending encoded light pulses to the receiver, which then decodes the signal into a hexadecimal value that your Arduino or Raspberry Pi can interpret. This makes it an excellent choice for remotely triggering relays, controlling robot movement, or navigating digital menus without physical contact.

Key Features

  • Complete Wireless Solution: Includes both the transmitter (remote) and the receiver module, allowing for out-of-the-box integration.

  • Universal 38KHz Frequency: Uses the industry-standard 38KHz modulation, ensuring high resistance to interference from ambient indoor lighting.

  • Low Power Consumption: The receiver consumes minimal current, making it ideal for battery-powered smart home devices and remote sensors.

  • Breadboard Friendly: The receiver module features standard 2.54mm headers for easy connection via jumper wires without soldering.

  • 21-Button Layout: Provides a wide range of control options, including numeric keys, navigation arrows, and functional "OK" and "Set" buttons.

Technical Details

  • Transmission Range: Offers reliable control up to 5-8 meters depending on the battery level and line-of-sight obstacles.

  • Receiver Sensitivity: Features an integrated PCM frequency filter to ensure only the 38KHz IR signal is processed.

  • Decoding Protocol: Compatible with the NEC Infrared Transmission Protocol, which is widely supported by Arduino libraries like IRremote.

  • Remote Power: Powered by a single 3V CR2025 lithium coin cell (often included with a protective pull-tab).

  • Signal Output: The module outputs a digital "Low" pulse when a signal is detected, making it easy to read via digital input pins.

  • Wide Operating Voltage: Works perfectly at 3.3V for ESP32/Raspberry Pi or 5V for Arduino Uno/Mega.

  • Hardware Robustness: The receiver sensor is encased in a metal shield to protect against electromagnetic interference (EMI).

  • Indicator LED: Many modules include a small onboard LED that flashes when a valid IR signal is received for easy debugging.

  • Compact Remote: Ultra-thin "credit card" style remote is lightweight and features a durable membrane keypad.

  • Multi-Device Support: Using custom codes, you can control multiple receivers independently using the same remote.

  • Logic Compatibility: TTL level output ensures direct connection to any standard GPIO without level shifting.

  • Angular Range: The 60-degree detection cone provides flexibility in where the remote is pointed relative to the receiver.

  • Long Shelf Life: The static power draw of the remote is virtually zero, ensuring the battery lasts for months of intermittent use.

  • Environmental Tolerance: Operates reliably in standard indoor temperatures (0°C to 50°C).

  • Easy Coding: Thousands of online tutorials exist for this specific kit, making it perfect for beginners and students.

Prototyping and Engineering Tips from Robogears

  • 9V Battery Use: Do not use a 9V battery to power the receiver module directly. Use the 5V or 3.3V pin from your Arduino. If you are building a remote-controlled car powered by 9V, ensure the IR receiver is connected to the regulated 5V rail of your motor driver or Arduino.

  • 18650 Cell: A single 18650 cell (3.7V) is perfect for powering the receiver module in portable projects. The receiver is highly tolerant of the slight voltage drop as the battery drains.

  • IC & Capacitor Tip: IR receivers can be sensitive to power supply noise from DC motors. If your remote stops working when your robot moves, add a 100uF Electrolytic Capacitor across the VCC and GND pins of the IR receiver to stabilize the voltage.

  • Related Products: We recommend pairing this with our Arduino Uno R3, 5V Relay Modules, and N20 Micro Gear Motors for building a remote-controlled robot.

Package Includes

  • 1 x 21-Button IR Remote Control (CR2025 battery included).
