MQ135 Gas Sensor Library for Proteus: Download & Updated Working Guide (2026)
The library file allows you to drag and drop a virtual representation of the into your Proteus schematic. It mimics the behavior of the real component, providing an analog voltage output corresponding to the concentration of gases it detects. The library usually consists of two files: MQ135.IDX (Index file) MQ135.LIB (Library file) Download MQ-135 Library for Proteus
Locate your Proteus installation folder. The default directory paths usually depend on your version: mq135 gas sensor library for proteus download upd work
Double-click the sensor from the search results and place it onto your schematic sheet. Connect the Pins: VCC: Connect to a +5V power source. GND: Connect to the ground terminal.

You can find these libraries on platforms like Instructables, GitHub, or component manufacturer websites. Search for "Arduino Gas Sensor Library for Proteus". Step 2: Install the Library
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. The default directory paths usually depend on your
Real MQ135 sensors interact with physical gas molecules. In a digital simulation, you mimic gas concentration using a variable voltage.
What (Arduino, PIC, 8051) are you pairing with the sensor?
Place a 100k potentiometer at the AO output. This allows you to manually simulate changing gas concentration during runtime.
Look for the "Gas Sensor Library for Proteus" on reputable engineering forums or GitHub repositories (often bundled as a "MQ Sensor Pack").
