By following this guide, you should now have a fully functional MQ135 sensor in your Proteus parts list. You can simulate air quality monitors, smoke detectors, and industrial safety systems without spending a dime on hardware.
To simulate gas levels, connect a Potentiometer (POT-HG) to the Test Pin of the MQ135. Connect the other ends of the pot to VCC and Ground. mq135 gas sensor library for proteus download upd work
Provides a general "Gas Sensor Library" that often includes multiple MQ-series sensors The Engineering Projects . Installation Steps By following this guide, you should now have
In real life, you would connect the MQ135’s analog output to a microcontroller’s ADC pin. But in Proteus, without a matching library, you cannot simulate this behavior. That is why custom libraries are essential. Connect the other ends of the pot to VCC and Ground
