You can find the necessary library files through several reputable community sources:
The Electronics: Provides a specialized MQ135 Gas Sensor Library specifically for Proteus simulation.
The Engineering Projects: Offers a Gas Sensor Library for Proteus that includes models for various MQ-series sensors.
GitHub Repositories: You can download raw library files directly from satyamkr80's GitHub or Karan-nevage's PROTEUS-LIBRARY, which contains a ZIP file of multiple sensor models. Step-by-Step Installation Guide
Once you have downloaded the ZIP or RAR file, follow these steps to install it:
Extract the Files: Open the downloaded package and extract the contents. You should see three primary file types: .LIB (Library), .IDX (Index), and often a .HEX file for the sensor's internal logic. Locate Proteus Library Folder:
Proteus 8: Navigate to C:\ProgramData\Labcenter Electronics\Proteus 8 Professional\LIBRARY.
Note: This folder is often hidden. Enable "Hidden Items" in your file explorer's View tab to see it.
Proteus 7: Go to the main installation directory, usually under Program Files (x86), and find the Library folder.
Copy and Paste: Copy the .LIB and .IDX files from your extracted folder and paste them into the Proteus LIBRARY folder.
Add Model Files (If applicable): If your download includes a .MOD file, paste it into the MODELS folder within the same Proteus directory.
Restart Proteus: If the software was open, close and restart it to refresh the component database. How to Use the MQ135 in Your Circuit
Search for Component: Go to 'Component Mode', click 'Pick from Library', and search for MQ135.
Configure the HEX File: Double-click the sensor on your workspace. Under the Program File field, select the folder icon and navigate to the .HEX file included in your download.
Simulate Gas Levels: Use the Test Pin on the sensor model. Connecting a Logic State or a button to this pin allows you to simulate high or low gas concentrations during the live run. Gas Sensor Library for Proteus - The Engineering Projects
MQ135 Gas Sensor Library for Proteus: Download and Installation Guide (Updated & Working) Once downloaded, follow these exact steps
If you are working on an air quality monitoring project or a smoke detection system in Proteus, you’ll quickly realize that the MQ135 sensor isn't included in the default component library. To simulate your circuit accurately without needing the physical hardware immediately, you need to manually add an external MQ135 library.
This guide provides the latest, updated working files and a step-by-step walkthrough to get your MQ135 gas sensor simulation up and running. What is the MQ135 Gas Sensor?
The MQ135 is a popular hazardous gas sensor used for detecting a wide range of gases, including: Ammonia (NH3) Nitrogen Oxides (NOx) Alcohol Benzene Smoke and CO2
In a Proteus simulation, the sensor typically features an analog output pin and a "Test Pin." Since Proteus cannot "smell" gas, the Test Pin allows you to use a potentiometer to simulate varying gas concentrations. Download the MQ135 Library for Proteus
To begin, you need the library files (usually a .LIB and .IDX file).
[Click Here to Download the MQ135 Proteus Library Files] (Search for reputable engineering blogs like The Engineering Projects or GitHub repositories for the latest .zip folder). Files included in the download: MQ135Sensor.LIB MQ135Sensor.IDX (Optional) A .HEX file for the sensor’s internal logic. How to Install the MQ135 Library in Proteus
Follow these steps to ensure the sensor appears in your component list: Step 1: Extract the Files
Once you’ve downloaded the .zip folder, extract the contents to your desktop. Step 2: Copy to Proteus Library Folder
You need to move the .LIB and .IDX files into the directory where Proteus stores its library data. The path varies depending on your version:
For Proteus 8 Professional:C:\ProgramData\Labcenter Electronics\Proteus 8 Professional\Data\LIBRARY(Note: ProgramData is often a hidden folder. Enable "Hidden Items" in Windows Explorer to see it.)
For Proteus 7:C:\Program Files (x23)\Labcenter Electronics\Proteus 7 Professional\LIBRARY Step 3: Restart Proteus
If you had Proteus open, close it and restart the software to refresh the component database. Simulating the MQ135 in your Circuit Once installed, follow these steps to build your circuit:
Pick the Device: Open the "Pick Devices" window (press 'P') and type "MQ135". Select the sensor and place it on your schematic.
Add a Potentiometer: To simulate gas levels, connect a Potentiometer (POT-HG) to the Test Pin of the MQ135. Connect the other ends of the pot to VCC and Ground.
Connect to Microcontroller: Connect the Analog Out pin of the MQ135 to an analog pin on your Arduino (e.g., A0) or PIC microcontroller.
Load the HEX file: Right-click the MQ135 sensor in Proteus, go to Edit Properties, and in the "Program File" section, upload the .HEX file that came with the library download. Troubleshooting "Library Not Found" Issues Now go ahead and build that gas leakage
Administrator Rights: Always run Proteus as an Administrator to ensure it has permission to read newly added library files.
Path Check: Double-check that you placed the files in the Data\LIBRARY folder, not just the root program folder.
Updated Files: Ensure you are using the "V2.0" or "Updated" versions of the library, as older versions may crash newer builds of Proteus 8.15+. Conclusion
Adding the MQ135 to your Proteus environment is essential for designing smart air quality monitors or industrial safety systems. By following this updated guide, you can move from software simulation to hardware implementation with confidence.
To get the MQ135 Gas Sensor working in Proteus, you must manually add the component files to the software's library folder. The sensor is not included in the standard Proteus installation. 1. Download Required Library Files
You can download the working library package (typically a .zip or .rar file) from trusted community sources like The Electronics or GitHub. The package must contain three essential files: MQ135.LIB (Library file) MQ135.IDX (Index file) MQ135.HEX (Simulation model file) 2. Install Files in Proteus
To make the sensor appear in your "Pick Devices" list, move the downloaded files to the following directory on your computer:
For Proteus 8.x: C:\ProgramData\Labcenter Electronics\Proteus 8 Professional\Data\LIBRARY
Note: ProgramData is a hidden folder. Enable "Hidden items" in Windows File Explorer to see it.
For Proteus 7.x: C:\Program Files (x86)\Labcenter Electronics\Proteus 7 Professional\LIBRARY 3. Configure the Sensor in your Schematic
Once the files are moved, restart Proteus and follow these steps to simulate:
Pick the Device: Search for MQ135 in the component mode and place it on your canvas.
Attach the HEX File: Double-click the placed sensor. In the Edit Component window, find the Program File field. Click the folder icon and select the MQ135.HEX file you downloaded earlier. Simulation Pins: VCC/GND: Connect to power and ground. OUT: Connect to your microcontroller's analog pin.
Test Pin: Connect a Logic State toggle. Setting this to 1 simulates the presence of gas, causing the OUT pin to go HIGH.
Many hobbyists have created simulation models. The most reliable one is from “Gravitech” or “Mikroelectronica” style models.
Recommended file names to search for:
When searching for libraries, you often see “UPD” in file names (e.g., MQ135_UPD_Proteus_Lib.zip). UPD stands for Updated – indicating that the library has been modified to:
A non-UPD library often fails because it was designed for Proteus 7 or lacks the necessary .IDX and .LIB files. Always prioritize UPD versions.
