At present, carbon monoxide sensors based on electrochemical measurement principle are widely used in coal mines. In order to solve the problems of low measurement accuracy, short calibration cycle, short probe life and false alarm caused by background gas interference, the paper designed a mine laser carbon monoxide sensor based on TDLAS.The sensor uses a lower power consumption VCSEL laser to replace the DFB laser. Meanwhile, it uses ARM and FPGA as the core, and realizes the real-time and accurate measurement of carbon monoxide. The test results show that the fundamental error of the sensor is no more than 2% of the measured value, the response time is less than 15s, and the reliability is high. It can effectively solve the problems existing in the sensor of electrochemical measurement principle. And it is of great significance to improve the reliability of coal mine safety monitoring and reduce the workload of sensor operation and maintenance.
