Final Verdict: Usable for demonstration and learning of gas sensor interfacing, but not reliable for accurate simulation of real-world gas sensing.
To simulate the MQ135 Gas Sensor in Proteus, you must download and manually add external library files to the softwareβs installation directory. Proteus does not include these sensors by default.

Publicly available libraries are rarely officially updated. The most common version (v1.0, 2017-2019) has known limitations:
No confirmed updates after 2022 from original authors. Any "update" likely refers to user modifications to the embedded model or HEX file.
| Pros | 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. |
Real MQ135 sensors have a heating coil (requires 150-200mA). In Proteus, add a resistor (33Ξ©, 2W) between VCC and the sensorβs H pins to simulate power consumption.
