Carbon Dioxide Sensor Module Based on NDIR Technology

Carbon Dioxide Sensor Module Based on NDIR Technology

In this paper, a gas detection system with an environmental compensation algorithm based on nondispersive infrared (NDIR) technology was designed. The prepared infrared pyroelectric detector was a dual-channel type based on the lithium tantalate (LiTaO<sub>3</sub>) wafer. The design of t...
