Description

This IR remote receiver module is engineered to capture and demodulate high-powered infrared signals from standard consumer remote controls operating at the 38kHz carrier frequency. It features two independent IR receiver chips, allowing users to physically orient the most sensitive sensor towards the signal source via a manual slide switch. The board outputs a clean, demodulated active-low signal envelope suitable for direct input to a microcontroller’s digital I/O or dedicated IR decoding library.

The module includes status LEDs for power and signal activity, and is supplied as a fully assembled and tested PCB. Its STEMMA JST PH connector simplifies integration into prototyping systems, while mounting holes provide options for secure enclosure installation. It is specifically designed for command decoding applications and is not suitable for proximity sensing or non-38kHz IR signals.

Key Features

  • Dual IR receiver ICs (TSOP38238 or equivalent) with selectable signal path via onboard slide switch.
  • Generates active-low, demodulated output signal compatible with common microcontroller IR libraries (e.g., IRremote).
  • Wide 3V to 5VDC operating voltage range for compatibility with 3.3V and 5V logic systems.
  • Onboard power (green) and signal activity (red) LEDs for immediate operational feedback.
  • Pre-assembled PCB with 2mm pitch STEMMA JST PH 3-pin plug for solderless, plug-and-play connectivity.
  • Includes mounting holes for secure mechanical integration into enclosures or devices.
  • Optimized for high-sensitivity reception of 38kHz modulated IR signals from standard remote controls.

Applications

  • Home automation systems for controlling lights, appliances, or media centers via existing IR remotes.
  • Prototyping and educational projects for learning IR communication and signal decoding with Arduino or Raspberry Pi.
  • Custom remote control interfaces for robotics or DIY electronics where standard IR commands are required.
  • Retro-fitting legacy IR-controlled devices into smart home ecosystems with microcontroller hubs.

Frequently Asked Questions

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

The module operates from 3 to 5 volts DC, making it directly compatible with both 3.3V and 5V microcontroller logic levels, such as those found on Arduino, Raspberry Pi, and ESP32 boards. Ensure your power supply is within this range for reliable operation.

How do I select between the two IR receiver chips on the board?

A manual slide switch is located on the PCB, allowing you to select which of the two IR receiver chips (positioned at the front or middle of the board) is active. This lets you physically orient the most sensitive sensor towards your remote control for optimal signal reception.

What type of connector does this module use, and is soldering required?

The module features a 3-pin STEMMA JST PH 2mm pitch connector, enabling plug-and-play wiring with compatible cables without any soldering. The output pin provides a demodulated active-low signal ready for connection to a digital input pin on your microcontroller.

Can this module receive IR signals other than 38kHz?

No, this receiver is specifically tuned for the 38kHz carrier frequency used by the vast majority of consumer infrared remote controls. It will not properly demodulate signals at other frequencies, such as those used for proximity sensing or different communication protocols.

How do I decode the IR signals with my microcontroller?

Connect the module's signal output to a digital input pin on your microcontroller (e.g., an Arduino). Use a popular library like IRremote to decode the received pulses into specific command codes. The red LED on the board will blink to confirm signal reception during operation.
