If you continue to face issues, consider joining the or r/Proteus on Reddit – many users share verified working versions of the MQ135 library.
To simulate the MQ135 gas sensor in Proteus, you'll need to download and install a library that models the sensor's behavior. Unfortunately, Proteus doesn't have a built-in library for the MQ135 sensor. However, you can create a custom library or use a third-party library.
Make sure you are pasting files into the ProgramData folder, not Program Files .
Open Proteus and launch a new or existing Schematic Capture project.
| | Cons | | :--- | :--- | | Essential for IoT Projects: Enables simulation of Air Quality/Pollution projects without physical hardware. | No Real-Time "Sniffing": You cannot "blow" into your computer to test it. You must manually change values (slide the pot) to see the output change. | | Visual Feedback: Most updated versions include a visual representation of the sensor "reading" or changing state. | Missing PPM Calculation: The raw library usually outputs voltage (0V-5V). The user must write the microcontroller code (C/C++ for Arduino or ASM for 8051) to convert this voltage into PPM (Parts Per Million). | | Easy Integration: Connects easily with standard microcontrollers (Arduino, 8051, PIC, AVR). | Installation Issues: Sometimes requires placing files in specific LIBRARY and MODELS folders manually if the automatic import fails. |

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).
