The IRM-H538M3/TR2 is a miniature infrared (IR) receiver module from Everlight Electronics, designed for remote control systems. This module demodulates the received infrared signal, outputting a signal that can be used by a microcontroller or other digital logic to interpret the remote control command. It's a compact and reliable solution for adding IR remote control functionality to various electronic devices.

Applications

• Televisions and Set-Top Boxes: For receiving remote control signals to change channels, adjust volume, and navigate menus.
• Audio/Video Equipment: In DVD players, Blu-ray players, amplifiers, and other A/V components for remote operation.
• Air Conditioners and HVAC Systems: Enabling remote control of temperature, fan speed, and mode settings.
• Home Automation Systems: Integrating with smart home hubs to control lighting, appliances, and other connected devices via IR remotes.
• Toys and Robotics: Used in remote-controlled toys and robots for wireless control.

Features

• Miniature Package: Compact size allows for easy integration into space-constrained designs.
• High Sensitivity: Excellent sensitivity to IR signals, ensuring reliable remote control operation even at a distance.
• Carrier Frequency: Designed to receive IR signals modulated at a carrier frequency of 38 kHz.
• Supply Voltage: Operates on a standard 5V supply voltage.
• TTL/CMOS Compatibility: Output signal is compatible with standard TTL and CMOS logic levels.

Benefits

• Simplified Remote Control Design: Integrates all necessary components for IR signal reception and demodulation into a single module.
• Improved Noise Immunity: Built-in filtering and signal processing techniques reduce the impact of ambient light and electrical noise.
• Long Operating Range: Enables reliable remote control operation over a considerable distance.
• Reduced Component Count: Simplifies the design and reduces the overall component count on the PCB.

Additional Details

The IRM-H538M3/TR2 operates within a specified supply voltage range, typically around 4.5V to 5.5V. It features a molded plastic package that provides physical protection for the internal components. The output signal is an active-low signal, meaning that it is normally high and goes low when an IR signal is detected. The module also includes an internal filter to suppress unwanted noise and interference.
