Reliability: High for logic-based testing. It accurately simulates the interaction between the sensor and microcontrollers like Arduino.

Functionality: Most libraries use a "Test Pin" to simulate gas presence. Setting this pin to HIGH triggers the sensor output, allowing you to verify if your code and circuit react correctly to detected pollutants.

Accuracy: Simulated results are ideal for functional testing but won't replace real-world calibration, as the MQ135 is sensitive to multiple gases (CO2, Ammonia, Benzene) simultaneously.

Compatibility: Works across most Proteus versions (7 and 8) and supports various microcontrollers. 🛠️ Key Features

Multi-Gas Detection: Simulates sensitivity to NH3, NOx, alcohol, benzene, smoke, and CO2.

Dual Output Simulation: Supports both analog (varying voltage) and digital (high/low) signal simulation.

Simple Integration: Easily interfaces with the standard Arduino Library for Proteus to build full air quality monitors. 📥 Installation Steps

To make the library work, you must place the following files in your Proteus LIBRARY folder:

MQ135.LIB / MQ135.IDX: These allow Proteus to recognize the component in the "Pick Devices" menu.

MQ135.HEX: This is the "internal" code for the sensor. Critical Step: You must double-click the sensor in your schematic and link this .hex file in the "Program File" section for it to function.
