Online analysis of carbon monoxide with the high-precision, high-sensitivity is of great significance to control environment pollution and industrial production-line process. The influence of these factors, such as input voltage variation of load and ripple to driver, were analyzed. The hybrid-driven power, with functions of slow-start, constant power laser diode control and over-current protection,...
An Unattended Detection method for monitoring the CO2 concentration in soil respiration is described. It is based on the gas pump and gas extraction with a dynamic air chamber assay, and the study of the relationship between data collected from on-line measurement of carbon dioxide and time, as well as the resistance to interfering. This method uses proposed utility line peak extraction method to...
