Research on carbon dioxide sensor based on non dispersive infrared technology

Published: 26 October 2022 Publication History

Abstract

In order to reduce the power consumption of carbon dioxide sensor and meet the application needs of multi-sensor long-distance load of coal mine safety monitoring system, carbon dioxide gas molecules are used in 4.2 ∼ 4.32 μ A low-power carbon dioxide sensor based on led-pr optical structure is designed. Based on the analysis of the principle of infrared carbon dioxide detection, LED light source and PR detector are studied.The design principle of LED light source driving circuit and the working mechanism of realizing low-power measurement, photoelectric signal processing circuit and software program flow are introduced. The power consumption of infrared carbon dioxide sensor is reduced to 0.06 W, which meets the needs of low-power detection applications in coal mines.
