| Abstract: | In order to monitoring carbon dioxide concentrations in the environment of CO2 geological storage area, one kind of portable carbon dioxide monitor is designed based on STM32F103RE micro controller. To realize data communication among micro controller , sensor,LCD Module, and USB storage Module under the protocol RS232.This system adopts three infrared absorption CO2 sensors and use relay control electric circuit switch three channels to collect classified data.Finally, made use of this monitor to carry out CO2 gas concentration experiment indoor,which shows three data acquisition channels work smoothly. |
