To simulate and test the MQ135 gas sensor in Proteus, we need a library that contains the sensor's model and characteristics. The library allows us to select the MQ135 sensor from a list of available components and place it in our circuit design. Without a library, we would not be able to simulate and test the sensor in Proteus. This folder may be hidden by default in
. Since Proteus does not include this sensor in its default library, you must manually download and install an external library file to use it in your simulations. 1. Download the MQ135 Library Files The library allows us to select the MQ135
