Abstract

This paper designs a TDLAS CO₂ gas detection system based on STM32H750. The system uses VCSEL laser as the core light source, and realizes the high precision and high sensitivity detection of CO₂ gas by combining hardware and software. The temperature control system developed in this paper can control the system temperature accurately, controlling the output wavelength of the laser and stabilizing the spectral line coefficient of the gas absorption line effectively. The accuracy and stability of the gas detection system are improved significantly.
