Description

The HS-S23A Infrared Receiver Module integrates a photodiode and a preamplifier circuit to receive and demodulate modulated infrared signals at 38 kHz. It outputs a clean, active-low digital signal, stripping away the carrier frequency for direct processing by a microcontroller’s digital input.

Designed for reliable operation in varied lighting conditions, the module includes internal filtering to reject ambient light noise. Its low power consumption and broad voltage compatibility make it suitable for integration into battery-powered devices, DIY electronics, and industrial remote control systems.

Key Features

  • Receives standard 38 kHz modulated infrared signals for universal remote compatibility.
  • Demodulated digital output (active-low) simplifies microcontroller interface and code.
  • Wide supply voltage range (2.5V to 5.5V) supports 3.3V and 5V logic systems.
  • High ambient light immunity due to integrated optical filter and signal conditioning.
  • Low power consumption design ideal for portable and always-on applications.
  • Compact form factor (31mm x 36mm) with pre-soldered 2.54mm pin header.
  • Includes mounting holes (3.2mm aperture, 10mm spacing) for secure installation.

Applications

  • Home automation systems for controlling lights, appliances, and AV equipment via IR remote.
  • DIY robotics and microcontroller projects (Arduino, Raspberry Pi, ESP32) requiring remote input.
  • Industrial equipment remote control and status signaling.
  • Educational electronics kits for learning about infrared communication and signal decoding.
  • Consumer electronics repair and custom remote control receiver replacements.

Frequently Asked Questions

What is the operating voltage range for the HS-S23A module?

The HS-S23A operates from 2.5V to 5.5V DC, making it directly compatible with both 3.3V and 5V microcontroller systems like Arduino, ESP32, and Raspberry Pi. Ensure your power supply is within this range for reliable demodulation and signal output.

How do I connect and read signals from this IR receiver with an Arduino?

Connect the module's V pin to 5V, G to GND, and the S (signal) pin to a digital input pin on the Arduino. Use a library like IRremote to decode the signals. The module outputs an active-low digital signal, meaning the pin goes LOW when a valid 38 kHz IR signal is detected.

Does this module work with all infrared remote controls?

It is designed to receive signals modulated at the standard 38 kHz carrier frequency, which is used by the vast majority of consumer remote controls (TV, AC, stereo). It will not decode signals using a different carrier frequency (e.g., 36 kHz or 40 kHz) without specific library support.

What is the purpose of the mounting holes on the PCB?

The two 3.2mm diameter holes with 10mm spacing allow for secure mechanical mounting of the module within an enclosure or on a panel. This helps position the IR sensor window correctly and reduces stress on the solder joints during installation.
