Precision Gas Sensing Interface Circuit with Digital Potentiometer-Based Dynamic Gain Control

This paper proposes a digital potentiometer-based adaptive gas sensor interface for stable detection without signal saturation under extreme environmental fluctuations. Conventional fixed-gain circuits often suffer from limited dynamic range, leading to data loss when severe baseline drifts exceed A...
