Overview

Randomized trial demonstrates stable gas detection in varying environments, suggesting enhanced sensor reliability.

Key Points

  • This research aims to develop a gas sensing interface that maintains detection stability under extreme environmental conditions.
  • Developed a digital potentiometer-based adaptive gas sensor interface.
  • Implemented a real-time control algorithm to adjust amplifier and attenuator gains.
  • Conducted experiments to test the interface's performance against ADC input limits.
  • The interface maintained stability with a buffer voltage of 2.75 V, exceeding the 1.2 V ADC limit.
  • Achieved a Mean Absolute Percentage Error of 1.628% for sensor resistance data.
  • Recorded a maximum relative error under 4.8% in various environmental conditions.
