The MQ135 Gas Sensor Library for Proteus allows you to simulate air quality monitoring by detecting gases such as Ammonia ( NH3cap N cap H sub 3 ), Nitrogen Oxides ( NOxcap N cap O sub x ), Alcohol, Benzene, smoke, and CO2cap C cap O sub 2
. Since the MQ135 is not a built-in component in standard Proteus installations, you must download and add an external library to use it in your schematic designs. Where to Download
Several community-contributed libraries are available for download:
The Electronics: Offers a dedicated MQ135 library including simulation HEX files The Electronics.
GitHub Repositories: You can find library files (LIB and IDX) from contributors like satyamkr80 or iamnarendrans.
The Engineering Projects (TEP): Provides a general "Gas Sensor Library" that often includes multiple MQ-series sensors The Engineering Projects. Installation Steps
To get the library working in Proteus 7 or 8, follow these steps: mq135 gas sensor library for proteus download upd work
Extract Files: Download and unzip the library folder. You should see files with extensions like .LIB, .IDX, and sometimes .HEX. Locate Proteus Library Folder:
Proteus 8: Navigate to C:\ProgramData\Labcenter Electronics\Proteus 8 Professional\LIBRARY. Note: ProgramData is a hidden folder; you may need to enable "Hidden Items" in Windows View settings.
Proteus 7: Navigate to C:\Program Files (x86)\Labcenter Electronics\Proteus 7 Professional\LIBRARY.
Copy and Paste: Move the .LIB and .IDX files into the Proteus LIBRARY folder.
Restart Proteus: Close and reopen the software to refresh the component database. How to Use the Sensor in Simulation
Once installed, you can find the sensor by searching for "MQ135" in the Pick Devices window.
Connection: The sensor typically features four pins: VCC (5V), GND, Analog Out (A0), and Digital Out (D0).
HEX File Requirement: For some versions, you must double-click the sensor in your schematic and link the provided .HEX file in the "Program File" property box to enable active simulation behavior.
Simulation Control: Many Proteus gas sensors include a "Test Pin" or logic toggle to simulate different gas concentrations, allowing you to see how your Arduino or microcontroller code reacts to changes. MQ135 Gas Sensor Simulation in proteus - The Electronics
The MQ135 gas sensor is a critical component for simulating air quality projects, capable of detecting ammonia (NH3), nitrogen oxides (NOx), alcohol, benzene, and CO2
. Since Proteus does not include this sensor in its default library, you must manually download and install an external library file to use it in your simulations. 1. Download the MQ135 Library Files
To get the sensor working, you need three specific file types: (Library), (Index), and (Hex code for simulation). The Electronics (Latest Version) : Download the MQ135 Gas Sensor Library from their official repository. GitHub (Source) : You can also find the individual files on the satyamkr80 GitHub Repository The Engineering Projects (Alternative) : A broader Gas Sensor Library
containing multiple MQ-series sensors (MQ2 to MQ9) is also available. The Engineering Projects 2. Installation Guide for Proteus 7 & 8
Once you have downloaded and extracted the ZIP/RAR file, follow these steps to install it: Copy the Files : Copy the files from the extracted folder. Locate the Library Folder Now go ahead and build that gas leakage
: Paste these files into the Proteus installation directory. The path varies by version: Proteus 8.x
C:\ProgramData\Labcenter Electronics\Proteus 8 Professional\LIBRARY ProgramData is often a hidden folder Proteus 7.x
C:\Program Files (x86)\Labcenter Electronics\Proteus 7 Professional\LIBRARY Restart Proteus
: If Proteus was open, close and restart it to refresh the component database. 3. How to Use the Sensor in Simulation
After installation, you must configure the sensor's internal code to make the simulation "work" and respond to inputs. MQ135 Gas Sensor Simulation in proteus - The Electronics
To integrate the MQ135 gas sensor into your Proteus simulations, you must download a third-party library and manually add it to your software's system folders. The MQ135 is a critical component for air quality projects, capable of detecting ammonia, benzene, alcohol, and smoke. Download Links for MQ135 Library
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. If this article helped you, share it with
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
The MQ135 is a chemiresistor – its internal resistance changes when exposed to certain gases. Key features include:
In real life, you would connect the MQ135’s analog output to a microcontroller’s ADC pin. But in Proteus, without a matching library, you cannot simulate this behavior. That is why custom libraries are essential.
