Verdict: Essential for IoT and Environmental Monitoring Simulations The MQ135 library for Proteus is a highly useful educational and prototyping tool. For engineering students and developers working on air quality monitoring systems, this library bridges the gap between hardware complexity and software simulation. The recent updates (upd) have significantly improved its stability, making it a reliable addition to the Proteus design suite.
