If you had Proteus open during this process, close the application completely. Restart Proteus to force the software to re-index its database and recognize the newly added MQ135 files. Verifying the Installation in Proteus
Both analog output (varying voltage) and digital output (high/low) are commonly available in module form. Why Use an MQ135 Library in Proteus?
Once you have downloaded and extracted the ZIP/RAR file, follow these steps to install it: Copy the Files : Copy the files from the extracted folder. Locate the Library Folder
Search for a trusted repository online (such as GitHub or engineering community blogs) hosting the "Gas Sensor Library for Proteus". Download the compressed ZIP folder. Once extracted, ensure you see two core files: MQ135SensorTEP.IDX (or similar .IDX file) MQ135SensorTEP.LIB (or similar .LIB file) Step 2: Locate your Proteus Installation Folder
