Introduction Proteus Design Suite is the gold standard for simulating electronic circuits before physically implementing them. However, one major frustration for engineers is the lack of ready-to-use models for modern sensors. The MQ135 Gas Sensor (used for detecting NH3, NOx, alcohol, benzene, smoke, and CO2) is a perfect example. You won’t find it in the default Proteus library. void loop() sensorValue = analogRead(A0); Serial
