摘要
Abstract
The principle of the Non-Dispersive Infrared (NDIR) is introduced, a multi-component gas-line detection system is designed based on Atmega128 that is a single - chip computer in this paper.The pnnciple and construction (hardware and software) are discussed. The advanced techniques include Filter related wheels and sample cell, highly sensitive infrared weak signal amplifier technique, low-power single-chip microcomputer, the experimental apparatus was simplified and the system detection sensitivity was improved ,which can realize the measurement for SOz, NO and N02 .关键词
