The Design of CO2 Detection Circuit Based on Facilities Environment
Abstract: The CO2 Detection Circuit is designed by using a sensor which absorbs CO2 .the principle and constitute of it is expatiated. The circuit have many advantage such as wide range of measure, higher sensitivity, fast response, better selectivity, strong anti-disturb and so on It’s easy to use, inexpensive display visual, and have better application foreground .
