Description

The Crowtail- IR Receiver 2.0 module is designed for decoding signals from infrared remote controls. Its core component, the HS0038B, integrates a photodiode, a pre-amplifier, and an internal bandpass filter tuned to 38kHz. This design effectively rejects continuous ambient light and electrical noise, allowing it to detect only the modulated IR pulses used by standard remote protocols.

The module outputs a clean, demodulated digital signal directly to a microcontroller’s input pin, simplifying the process of reading and decoding common IR command sets like NEC, Sony SIRC, and RC-5. Its compact PCB and standardized Crowtail edge connector facilitate rapid integration into prototyping projects and embedded systems requiring remote control functionality.

Key Features

  • Standardized IR Receiver: Utilizes the widely-adopted HS0038B IC, ensuring compatibility with a vast library of existing IR decoding software and remote controls.
  • Integrated Signal Conditioning: The built-in 38kHz demodulator provides a noise-immune digital output, eliminating the need for external filtering circuitry.
  • Broad Protocol Support: Capable of receiving signals encoded with all major infrared transmission codes used in consumer electronics.
  • Optimized Form Factor: The miniaturized 20mm x 20mm PCB is designed for space-constrained applications and easy mounting.
  • Plug-and-Play Connectivity: The Crowtail connector system allows for tool-free connection to compatible baseboards, speeding up prototyping.
  • High-Value Build: Offers a reliable and durable construction suitable for educational, hobbyist, and prototyping environments.

Applications

  • Consumer Electronics Remote Control Replication: Decoding commands from TV, stereo, or air conditioner remotes for home automation projects.
  • Robotics and DIY Remote Control: Adding wireless infrared control capabilities to mobile robots, drones, or custom gadgets.
  • Interactive Installations and Kiosks: Creating touchless interfaces triggered by standard IR remote commands in public displays or art installations.

Frequently Asked Questions

What is the operating voltage range for this IR receiver module?

The module is designed to operate from 3.3V to 5V DC. This wide range makes it directly compatible with most common microcontroller platforms, including 3.3V systems like the Raspberry Pi and ESP32, as well as traditional 5V Arduino boards. Ensure your power supply provides a stable voltage within this range.

Which infrared remote protocols does this module support?

The HS0038B receiver IC demodulates the 38kHz carrier frequency used by most common IR remote protocols. It can receive signals encoded with standards such as NEC, Sony SIRC, Philips RC-5, RC-6, and many others. Decoding the specific command bits is handled in software on your connected microcontroller using libraries like IRremote.

What is the maximum reliable reception distance?

Under typical line-of-sight conditions with a standard remote control, the module provides effective reception up to approximately 10 meters. Performance beyond this range is not guaranteed and can be affected by ambient light interference, the power of the transmitting IR LED, and obstacles between the transmitter and receiver.

How do I connect this module to an Arduino or Raspberry Pi?

The module uses a 3-pin Crowtail connector (VCC, GND, SIG). For direct connection, wire VCC to your board's 3.3V or 5V pin, GND to ground, and the SIG (signal) pin to any digital input pin on your microcontroller. For Raspberry Pi, ensure you use a 3.3V power source. You can also use it with an Elecrow Crowtail base shield for plug-and-play operation.
