To get the TSOP1738 IR receiver working in Proteus, you typically need to download and install a custom library since it is not always included in the default component database. 1. Download the TSOP1738 Library

You can download external library files for the TSOP1738 from reputable engineering community sites.

The Engineering Projects (TEP): This site is a common source for these files. Look for the "Infrared Sensor Library for Proteus" or a specific TSOP1738 package.

GitHub: Community-maintained repositories like Proteus-Libraries often include IR sensor models. tsop1738 proteus library download

Electronicstreet: Offers newer Proteus component libraries that may include IR receivers. 2. Installation Steps

Once you have downloaded the .zip or .rar file, follow these steps to add it to Proteus:

Infrared Sensor Library for Proteus - The Engineering Projects

The TSOP1738 is a specialized IR receiver used for remote control applications. While it is not always available in the standard Proteus component library, you can download and install external libraries to simulate it. TSOP1738 Library Downloads

You can download library files for the TSOP1738 and related IR sensors from the following sources:

The Engineering Projects: Offers a comprehensive Infrared Sensor Library and IR Proximity Sensor Library that includes models compatible with TSOP sensors.

GitHub (IRX Library): The IRX-Proteus repository provides a library for infrared remote simulation, including .LIB and .IDX files required for Proteus 8.12 and newer.

Toddresbogascont1971's Ownd: Provides a specific TSOP1738 library download containing three library files for extraction. How to Install the Library

Once you have downloaded the .zip or .rar file, follow these steps to add it to Proteus:

Extract the Files: You will typically find three files: .LIB, .IDX, and sometimes a .HEX or .MDF file. What is TSOP1738

Locate the Library Folder: Navigate to your Proteus installation directory. This is usually:

C:\Program Files (x86)\Labcenter Electronics\Proteus 8 Professional\Data\LIBRARY

Or C:\Program Data\Labcenter Electronics\Proteus 8 Professional\LIBRARY (this folder may be hidden).

Paste the Files: Copy and paste all extracted files directly into the LIBRARY folder.

Restart Proteus: If the software was open, close and restart it to refresh the component database.

Search for Component: Go to the schematic capture, click 'P' (Pick Devices), and search for "TSOP1738" or "Infrared Sensor".

3. Simulation via Substitution (No Library Needed – Workaround)

If you cannot find a working library file, simulate the TSOP1738 using:

  • A voltage-controlled switch + pulse source (for 38 kHz)
  • Or simply use a generic IR receiver model called IRLINK or IRRX found in some third-party Proteus libraries.

⚠️ Warning: Avoid executable (.exe) files claiming to “auto-install” Proteus libraries. Many contain malware. Stick to .LIB, .IDX, or .PDIF files.

4.1. Using the TSOP4838 as a Substitute

Proteus includes TSOP4838 in the Optoelectronics library. Electrically, it is identical to TSOP1738 for simulation (active-low output, 38 kHz carrier detection).
How to use: Visit the Proteus Library Website : Go to

  • Pick TSOP4838 from Optoelectronics → IR RECEIVER.
  • Connect pin 1 (OUT) → your microcontroller or logic.
  • Connect pin 2 (GND) and pin 3 (VS = +5V).

5. Testing the Library

After obtaining or creating the part:

  1. Test circuit: IR LED (connected to 38 kHz square wave) → pointed at TSOP1738 → output to logic analyzer or LED.
  2. Expected behavior: Output goes LOW within ~10 µs of receiving 38 kHz carrier, returns HIGH after carrier stops (with ~10 ms dropout delay).
  3. Troubleshooting: If output always HIGH → check GND and VS connections. If always LOW → check for floating input.

Part 10: Frequently Asked Questions (FAQ)

Q1: Is TSOP1738 same as TSOP38238?
Yes, functionally identical. The TSOP38238 is the modern replacement, but for simulation, the model works interchangeably.

Q2: Does the library simulate the 38 kHz bandpass filter?
Most good libraries do – they output LOW only when a 38 kHz ± 2 kHz modulated signal is present.

Q3: Can I use this library with Proteus 7?
Yes, the .LIB format is backward compatible. For Proteus 7, use the legacy version (avoid HEX models).

Q4: What about TSOP1738 Arduino simulation?
Combine this library with the Arduino Uno Proteus library (available from The Engineering Projects) for a complete IR remote control simulation.

Q5: Why does my simulation show “No model specified”?
The downloaded library file is incomplete. Look for a file with the same name but .MODEL extension inside the library ZIP.

Expected output:

  • When IR signal is present: OUT pin = LOW → LED turns ON.
  • When no IR signal: OUT pin = HIGH (via pull-up) → LED OFF.

If this works, your TSOP1738 Proteus library download is successful.
