Connect a or Logic Toggle to the Test Pin of the MQ135. Logic 0: Represents clean air (Normal output).
If you have already downloaded the MQ135 library and want to update it to the latest version, follow these steps:
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) mq135 gas sensor library for proteus download upd work
C:\ProgramData\Labcenter Electronics\Proteus 8 Professional\Data\LIBRARY
Now that the library is installed, here’s a practical circuit to test it. Connect a or Logic Toggle to the Test Pin of the MQ135
Because the MQ135 model relies on a .hex file, the simulation might run slower than a standard resistive component.

Proteus Design Suite is the gold standard for simulating electronic circuits before physically implementing them. However, one major frustration for engineers is the lack of ready-to-use models for modern sensors. The (used for detecting NH3, NOx, alcohol, benzene, smoke, and CO2) is a perfect example. You won’t find it in the default Proteus library.
