Abstract

The invention discloses a carbon dioxide detection system based on signal buffering, which is characterized in that: mainly composed of a carbon dioxide sensor H, an amplifier P1, an amplifier P2, and a display, one end is connected to the signal output end of the carbon dioxide sensor H, and the other end is connected to the amplifier through a resistor R3 The negative electrode of P1 is connected to the resistor R1 and so on. The present invention can collect the carbon dioxide concentration signal in the environment, and filter the interference signal in the signal to make the detection signal cleaner. At the same time, the present invention can also amplify the detection signal and increase the amplitude of the detection signal, so that accurate detection can be achieved The concentration of carbon dioxide in the environment.

Description

technical field [0001] The invention relates to a detection system, in particular to a carbon dioxide detection system based on signal buffering. Background technique [0002] With the progress of human society and the development of science and technology, people's living standards have been rapidly improved, and the scale of industrial production has also rapidly expanded, but at the same time it has led to a double increase in carbon dioxide emissions, such as the greenhouse effect and the acceleration of land desertification. It affects and destroys the living environment of human beings. In recent years, with the enhancement of people's awareness of environmental protection, people have begun to control the environment. In the process of treatment, carbon dioxide needs to be detected. At present, the methods for detecting carbon dioxide mainly include chemical methods, gas chromatography, and volumetric titration methods. These methods The defects of high price and low...
