Hello friends, I hope you all are doing great. Today, I am going to share the new Gas Sensor Library for Proteus V2.0 . It simulates the popular MQ-2 gas sensor module : the MQ-2 sensor in its steel mesh cap on the small blue board with the LM393 comparator. With this Gas Sensor Library for Proteus , you fill a little kitchen with LPG, smoke, alcohol, methane or hydrogen, and your Arduino reads the MQ-2's analog output A0 and its digital output D0, just like on a real board. We have published gas sensor libraries for Proteus before, but version 2.0 is a completely new model. A0 is now a real analog voltage that follows the datasheet curves, the heater has to warm up like a real one, and the gas reaches the sensor with a lag , so your sketch sees the same slow, curved response as on real ha ...
