Evaluation of Low-Cost CO₂ Sensors Using Reference Instruments and Standard Gases for Indoor Use

CO₂ monitoring is important for carbon emission evaluation. Low-cost and medium-precision sensors (LCSs) have become an exploratory direction for CO₂ observation under complex emission conditions in cities. Here, we used a calibration method that improve...
