The Concentration Of Mathane Monitoring Based On Single Chip Computer

The concentration of mathane monitor controlled by chip microprocessors, is able to sound the alarm bell based on the limit of mathane concentration, and start device to drain the gas at the same time.The instrument include CPU, sensitive element, Canmengou monitoring circuit, little signal amplify circuit, A/D transform circuit, communication circuit, display circuit, monitoring circuit, CPU is the core in the instrument, complete data gather, process, export, display and so on. Sensitive element is one of the important to measure the concentration of mathane, and it' s export is a little voltage signal, little signal amplify circuit is to transform the analogue signal to digital signal, display circuit is to display the concentration of mathane, monitoring circuit is to monitor the overstep limit of mathane concentration.The feature is new design, accurately measure parameter, convenient to operate and so on.
