Published by: Embedded Tech Hub Reading time: 8 minutes Introduction Simulation is the backbone of modern electronics design. Before soldering a single component, engineers rely on software like Proteus Design Suite to test circuits, debug code, and predict behavior. However, one of the biggest hurdles for hobbyists and professionals alike is the lack of ready-to-use simulation models for specific sensors. And remember – simulation saves time, but always
