Close and reopen Proteus for the library index to refresh.
However, the default Proteus library does not include the MQ135 sensor. This article provides an updated guide to downloading the MQ135 Proteus library, installing it, and working with it in your simulations. What is the MQ135 Sensor? mq135 gas sensor library for proteus download upd work
Even with proper installation, users may encounter issues when using the MQ135 library. Here are the most common problems and their solutions:
For some versions, you must double-click the sensor in your schematic and link the provided .HEX file in the "Program File" property box to enable active simulation behavior.
However, the default Proteus library often lacks specific MQ-series sensors. This article provides a comprehensive, updated guide on downloading, installing, and utilizing the , ensuring your simulations work flawlessly in 2026.

When you run the simulation, you can click on the arrows on the MQ135 component to increase or decrease the gas density , simulating a rise or fall in air pollution. 4. Example Circuit: MQ135 with Arduino in Proteus
If the sensor does not show up or the simulation crashes, check the following:
Once the files are moved, restart Proteus and follow these steps to simulate: This article provides an updated guide to downloading
The for Proteus allows you to simulate air quality monitoring by detecting gases such as Ammonia ( NH3cap N cap H sub 3 ), Nitrogen Oxides ( NOxcap N cap O sub x ), Alcohol, Benzene, smoke, and CO2cap C cap O sub 2
