Absolutely. Use a voltage probe on the AO pin and a comparator IC (like LM393) on the DO pin. The library works standalone.
Real MQ135 sensors interact with physical gas molecules. In a digital simulation, you mimic gas concentration using a variable voltage. mq135 gas sensor library for proteus download upd work
