基于NDIR技术的封闭空间CO2传感系统构建
Construction of a CO2 Sensing System for Enclosed Spaces Based on NDIR Technology
摘要
Abstract
Enclosed spaces,especially crowded areas such as university sports venues and libraries,of-ten experience excessive CO2 concentrations due to insufficient ventilation,which not only endangers peo-ple's physical and mental health,but also diminishes the quality of activities and learning.To achieve accu-rate and real-time monitoring of CO2 levels in such environments,a sensing system based on Non-Dis-persive Infrared(NDIR)technology is developed.The system incorporates synergistic optimizations at both the hardware architecture design and signal processing algorithm levels,thereby enhancing its meas-urement performance and practical applicability for CO2 sensing in enclosed spaces.Experimental results show that the system significantly improves the capability for the real-time monitoring and early warning for CO2 concentrations in enclosed spaces,effectively safeguarding the physical and mental health of occu-pants in enclosed spaces.关键词
