English Abstract

The measurement of the concentration of CO2 in air is very important in industry, agriculture, medicine, hygiene, environmental protection and many other fields. But most instruments used or available in the market for CO2 measurement are analysis instruments with very complicated mechanism and high prices thus limiting their applications. The development of the low-price instrument to measure the concentration of CO2 in air is therefore urgent. The paper discusses the working principle and the structure of the simple infrared CO2 monitor based on the infrared technique and an advanced microprocessor. The principle to simplify the hardware of the monitor and to improve its sensitivity and accuracy in the measurement is illustrated. The experimental results have shown that the technique can be adopted to produce the gas composition analyzer at low cost.
