The MQ135 Gas Sensor Library is an essential add-on for electronics students and engineers who need to simulate Air Quality monitoring systems. The standard Proteus library does not include gas sensors, making this third-party TEHE (TechSat) model the go-to solution. The "UPD" (updated) versions circulating online are generally stable and compatible with modern Proteus versions.
Search online for updated Proteus library packages provided by engineering communities, GitHub repositories, or electronics blogs (such as The Engineering Projects). Ensure the package is explicitly marked as working for your version of Proteus (e.g., Proteus 8.x).

If the sensor does not appear when typing the keyword, the files are likely in the wrong directory. Double-check that the .LIB files are in the ProgramData path rather than the Program Files path for Proteus 8+. "Model Not Found" Simulation Crash

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.
The sensor module should appear in the results list. Double-click it to add it to your devices list, then place it onto your schematic workspace. Step 4: Simulating the MQ135 (Ensuring it Works) Search online for updated Proteus library packages provided
The default library folder location for Proteus 8 Professional is:
Typically located at: C:\Program Files (x86)\Labcenter Electronics\Proteus 8 Professional\DATA\LIBRARY
You can find the MQ135 library for Proteus through sites like The Electronics The Engineering Projects The download usually contains three essential file types:
For Proteus to recognize the new component, you must place the extracted files into the correct installation directory. Close Proteus if it is currently running.
