Abstract
The methods for Multi-component gas monitoring combination with multi-windows infrared sensor can be to detect and analyze conventional gas such as CO2 in the atmosphere based on the non-dispersive infrared (NDIR) detection technology, and can adapt to multi-task and multi-parameter measurement, convert the monitoring object to complete the different monitoring tasks at any time. First, the principle of the NDIR technology was described in this paper, and proposed a targeted circuit design and key technology solutions. The preliminary experimental analysis was shown that the test result is valid. NDIR infrared gas detection method as rapid and accurate gas analysis techniques can be generally used in the detection of continuous emission monitoring system as well as motor vehicle exhaust.
